Step-by-step instructions on how to fix a network error yourself without access to the Internet. Windows cannot access a computer on the local network. Shared connection. What to do.

I decided today to prepare a small instruction with solutions to the problem when, when setting up the distribution of Internet via Wi-Fi in Windows 10, it is not possible to open Internet connection sharing.

How does a virtual Wi-Fi network work in Windows 10?   And not only in the "top ten", in Windows 7 everything is exactly the same. First, we use the commands, or through a special program to launch the access point. After that, our laptop already distributes Wi-Fi network, but it is without access to the Internet. That is, the network itself is there, you can connect to it, but the Internet will not work. Why? Yes, because you need to provide general access to the Internet. What does it mean. We, in the properties of the connection through which we connect to the Internet, must enable Internet sharing for the virtual Wi-Fi network that we launched.

Below we will consider the problems that often arise when setting up shared access for a virtual Wi-Fi network in Windows 10. It is not uncommon for people to share useful solutions to various problems in the comments to various articles. For which they thank you more!

There is no way to select a connection when opening Internet sharing

I have already seen comments on this issue more than once. Also, in the comments shared the decision. The problem is as follows. We started distributing Wi-Fi networks in Windows 10, on the page with adapters there is "Local Area Connection * 12" (the figure may be different). Now, we need to provide Internet access for this connection.

We go into the properties of our internet connection (usually an “Ethernet” or high-speed connection), go to the "Access" tab, put a check mark next to the item "Allow other network users to use the Internet connection of this computer", and we see that there is no way to select "Connect to a home network". There is only "Wireless Network", and there is no drop-down menu in which you need to select "Local Area Connection *". It looks like this:

Decision.   Open the properties of the adapter through which you have Internet access. It does not have to be an Ethernet adapter. Then, just uncheck "Allow other users ..." and click Ok.

Then, again, open the properties of the same adapter, put a checkmark next to "Allow other network users to use the Internet connection of this computer," and a menu should appear below, in which we can select our "Local Area Connection *", which we launched. Click Ok.

You can also try to disable and enable the adapter (right-clicking on it and selecting the appropriate item), and then check again. After these steps, access to the Internet via the Wi-Fi network that we launched on the laptop should appear.

If you still have no opportunity to select a home network from the list, then make sure that it is running. Where all the adapters are: “Ethernet”, “Wireless Network”, there should be “Local Area Connection *” with some number.

If you know any other solutions to this problem, then I ask you to share them in the comments to this article.

There is no "Access" tab in the connection properties in Windows 10

By opening internet connection properties (to provide general access to the Internet), you may find that there is no tab "Access"on which you actually need to configure sharing.

1 First of all, you need to make sure that in the "Network and Internet" - "Network Connections" settings there is "Local Area Connection *". This means that the virtual network is running. If it is not there, then you need to start the network according to the instructions, the link to which I gave above.

2 If you have only one connection there, for example, "Ethernet", then this tab will not be, since there is not a single connection for which you can configure sharing. You need to install the driver on the Wi-Fi adapter, and start the virtual network.

3 Perhaps you have already checked "Allow other network users ..." in the properties of other connections, for example, "Wireless Network". Uncheck this box for all connections. (which is possible), and the "Access" tab should appear.

4 If you have Windows 7, then in the initial version of "Starter" there is no way to share. In the home version of Windows 10, I did not notice any problems with this.

If I find out any more information on this topic, I will definitely add it to this article. And you can share your experience in the comments, or ask questions, we will understand.

Today for many it is already an urgent need. Modern equipment and operating systems are becoming more intelligent, and the user is less likely to need to do something to configure. However, occasionally such a need arises. Today we will tell you how to solve the problem if the computer reports that you are connected to the network without access to the Internet, and near the connections icon you see a yellow triangle with an exclamation mark.

Microsoft operating systems, starting with Windows 7, constantly monitor network connections, and as soon as the global network is unavailable, they immediately report it. The reasons why the computer may not be connected to the Internet are not so small. These may be problems with the provider, incorrect configuration of the equipment by the user, or malfunctioning of the network protocols. Today, the new IPv6 protocol is gaining ground, but its percentage is still very small, especially in home networks, so the main attention will be paid to the old version - IPv4.

Connection through a router via a network cable without access to the Internet

Provider issues

Yesterday everything worked, and today this warning appeared. If this happened to you for no apparent reason, then in most cases the provider has a problem. Therefore, before doing anything on your own, call technical support. Most often, data transmission lines are damaged, some technical work is being carried out, or you just forgot to top up your account on time.

Perhaps you will hear in response that everything works fine for the provider, then you need to check your network and, if necessary, configure it. The support service will probably offer the services of its master, but, firstly, its services are not free, and secondly, for the time that the master gets to you, you can manage to solve the problem yourself.

Physical Connection Problem

Not so rare cases where the fault is a partially broken network cable or a loose connection in the connector. And if you have pets or children, then the likelihood of such a development of events increases. Even Wi-Fi users should not forget that a cable is also stretched to the wireless router. Check the integrity of the entire wiring - whether there are strong bends anywhere, whether all the plugs are firmly inserted into the sockets and whether they are inserted where you really need to. Provided that no problem has been detected here, we proceed to the next step.

Connecting to a Windows 7 LAN without Internet access

It happens that the installed router hangs corny. In this case, it helps. To do this, just turn off his power and after a few seconds connect again. It does not hurt to restart the computer at the same time. If it happens that such router freezes occur with annoying regularity, consider buying a new device. You should also try connecting the Internet cable directly to your PC or laptop. If there is no result, we will first deal with the computer.

Checking computer settings

It is possible that the problem arose “out of the blue”, then there should not be any questions with the settings on the computer, much more often the problem occurs during the initial configuration or making any changes to an already working network. First of all, you need to check the correct IP address of the computer, for which press Win + R on the keyboard at the same time. The Run window opens. Type ncpa.cpl in its line and click OK. The network connection window appears. It may happen that there are several of them, but the necessary ones will not be crossed out with a red cross and its name is similar to “Local Area Connection” or “Wireless Connection” (if using Wi-Fi). Right-click on the desired connection and go to the properties, where the list will contain lines with IPv4 and IPv6 entries. Check the box next to IPv6, and on IPv4, double-click. Check the items to automatically receive settings and save the changes. If Internet access does not appear, go ahead.

Setting up a LAN connection in Windows 7

We find out the address of the router

Perhaps, in the previous window, nothing had to be done, the settings for obtaining IPv4 and IPv6 protocol addresses were automatic and everything was initially as it should. Then you only need to configure the router, for which you need to know its address. Right-click on the connection again and select “Status”, and then click “Details”. In the window that appears, there will be several lines, we are interested in "IPv4 Address". If you see a record of the type 192.168.x.x, remember or write down what is indicated opposite the “IPv4 DHCP Server” - this will be its address. It may be that the computer is not able to get the settings automatically, then the record will look like 169.254.x.x. You can find out the IP router from the documentation for it, or it is indicated on the device’s case, and most often it is 192.168.0.1 or 192.168.1.1. Open your browser and enter the set IP in the address bar, and if it is correct, you will be asked to enter your login and password.

Properties of “Internet Protocol Version 4 (TCP / IPv4)”

Setting up the internal network on the router

After entering the credentials correctly, you will be taken to the control panel of the router, and further actions depend on the model of the device and its firmware. You need to find the management of the DHCP server, which is responsible for automatically receiving devices IP addresses and other parameters necessary for the network to function normally. Look for blocks that name DHCP settings, DHCP server, or the like. The block will contain a switch with the values \u200b\u200bEnable or Disable. Most often, these settings are located in the LAN section. Turn on the DHCP server, save the changes and reboot the router. Field of this, a connection to the Internet will appear on the computer.

Check the connection settings to the provider

You should not make hasty conclusions if the previous steps did not help to configure the connection. Once the network still does not work normally, we check the connection with the provider, for which, in the router control panel, go to the appropriate section. In almost all manufacturers, these options are called WAN or Internet. There are quite a few options in this section. Which ones are designed for you can be found in the contract or in the technical support of your service provider.

Reinstalling network card drivers and checking the firewall

It makes sense to do this when you are sure that all the previous settings are correct, the connection with the provider is established, but the network cannot be configured normally. The best option is to download the latest version of the driver from the manufacturer’s website, for which, it seems, you have to go to a friend or neighbor. In the absence of such a possibility, the driver that is included on the installation disk is quite suitable. After reinstalling, be sure to restart your computer. It should also be noted that there are failures in the drivers arising from the installed software, which makes changes to the operation of network protocols on the computer. The most common representatives are antiviruses and firewalls. Make sure that such programs are not installed, and if you have them, disconnect or delete them during the test, as they may block the connection.

Replacing the MAC address of a network card

Problems with MAC addresses sometimes arise in cases where the network is very large, but it is still worth excluding it. On your computer, go to the device manager, for which press Win + R, enter devmgmt.msc and click on OK. The device manager will start, where you need to find the "Network Adapters" section, expand it and select the network card with which the PC is connected. After double-clicking on it, in a new window, on the "Advanced" tab, select the Network address parameter and enter any twelve digits in the empty field to the right. After that, we reboot and look at the result.

Clearing the DNS cache and resetting TCP / IP

The following steps will reset all network settings for IPv6 and v4, so you must complete them. If you are ready for this, and you have information about all the settings (recorded somewhere, for example), find the command line in the Start menu and run it with administrator rights. Enter the following commands in the window that appears, confirming your entry by pressing Enter. After working out each command, restart the computer and check the result.

1. ipconfig / flushdns
2. netsh winsock reset
3. netsh int ip reset c: \\ resetlog.txt - this command will completely reset all connections and you will have to configure them again!

Clearing the DNS cache using the command line

You have a direct connection to the provider

The option when your computer is connected directly to the provider, bypassing the router, is now becoming less common, since the number of network devices is growing steadily. But what if you have just such a connection? Fix possible problems with the drivers as described above, and check the connection settings are correct. Regarding the settings, the best option would be to contact technical support, since there are a lot of variations.

Nothing helped at all.

Maybe you are lucky, and your provider provides access using the new IPv6 protocol, the configuration of which requires knowledge of some subtleties. It should be noted that the expansion of the use of IPv6 is inevitable, since the address space of the previous version of the protocol, IPv4, has come to an end, and the global network is growing every day. Since the efforts were spent, but your network did not work, then there is only one piece of advice - call the wizard. It is quite possible that the problem that has arisen is non-standard or that it requires replacement / repair of equipment to solve it.

There is Internet access, but the error remains

Such a situation may well be. The reasons can be different - most often when connecting through a proxy server. However, there is one solution. Press Win + R, enter gpedit.msc - this will bring you to the local group policy editor. In the menu on the left, go to the following items: Local Computer Policy - Computer Configuration - Administrative Templates - System - Internet Connection Management - Internet Connection Settings. Now, in the right part of the window, find and enable the "Disable active sounding for the network connection status indicator". In Windows 10, this option is called "Disable active network connection health checks." Keep in mind the fact that now even with a really missing connection, the message will not appear.

Conclusion

This article contains the most common problems associated with the error "Network without access to the Internet" and suggests ways to solve it. We hope that the material was interesting to you and helped to independently overcome the difficulties that arose.

What is Internet Sharing?

Shared Internet access for organizations is the most common solution. However, there are times when large organizations do not have a common Internet. More precisely, there is no single and common Internet access for the entire organization, for example, some departments work through a dedicated line, and some employees use dial-up access modems to access the Internet. But there are more deplorable situations when the system administrator does not even know that any department ordered and uses a special dedicated line.

Pros and Cons of Shared Internet Access

Naturally, shared Internet access helps an organization keep its costs on the Internet under control, and most importantly, ensure network security. Generally speaking, the unauthorized creation of Internet access channels by users should be prohibited not only by administrative, but also by technical measures. The network administrator must know what connections and channels exist on the corporate network, and especially where it is open for exchanging information with the Internet, in order to protect the network from threats originating from the Internet.

Thus, we will further consider the situation when an organization has one or more centralized Internet connections through which all employees of the organization have common Internet access. The situation with confusion in Internet connections is clearly abnormal and should be, first of all, solved by administrative decisions.

The shared Internet in the organization has a number of significant advantages. This is first of all:

1. the ability to control the Internet - all information flows incoming or outgoing from the organization’s local network.
2. the ability to install firewalls in the path of all incoming and outgoing IP packets to provide centralized network protection.
3. the ability to control the total costs of the organization on the Internet.
4. possibility of general accounting of traffic and control of user behavior on the Internet for the entire organization.
5. More efficient use of funds: the provider’s two slow channels usually cost more than one fast one, traffic with large volumes of consumption can be cheaper. In addition, the so-called statistical multiplexing allows you to use the resources of the Internet channel for sharing more efficiently.

All this does not mean that the organization should have one Internet channel. There may be several, but general Internet access requires centralized management of them, when all channels are considered as a single pool through which shared Internet access is provided.

Speaking about the advantages of shared Internet access in an organization, it is necessary to say what difficulties are present in it. The difficulties are usually associated with the fact that all users have shared access and, therefore, have an impact on each other. In practice, it often happens that downloading a large file by someone can take up all the resources of a common channel and prevent, for example, bookkeeping, from making an electronic payment. Thus, for the general Internet, the tasks of controlling, accounting, and controlling user access become extremely important. In other words, those features that are mentioned as the benefits of shared Internet access become necessary to realize!

How is Internet access shared?

In order to understand how the tasks of traffic accounting, user rights management, and network protection can be solved, it is necessary to understand how general Internet access is arranged. Consider several scenarios for organizing shared Internet access.

Shared Internet access for local area network

In the simplest case, the organization’s corporate network is a single local area network that is connected to the Internet through a leased line, an Ethernet network of an office building or a home network. In this case, the channel equipment is most often included in the LAN switch: xDSL modem / router or PPPoE / PPTP router, which works with the provider's office or home network.

The administrator’s ability to manage and control such a network will be limited by the settings available in the modem / router. As a rule, these are fairly cheap devices, the control capabilities of which may be limited.

Corporate network with distributed offices and a centralized channel

In this case, the organization has its own departmental network, ordering leased lines between its offices and combining their local networks into a single routed space. One of the offices, well located geographically, becomes the center where the Internet channel from the provider is laid. As a rule, in this case, the routing equipment for combining the local networks of individual offices has developed management and accounting capabilities. Also, organizations with such a network structure install separate systems - Internet control servers in order to solve the problems of traffic accounting and user access control. Internet control servers give IT staff more flexibility and help them use the powerful functions of routing equipment. For example, turning a report on traffic consumption by IP addresses into statistics for specific users. Network protection can be implemented by separate specialized devices or be one of the functions of the Internet server control. Rational use for general access of the main and backup Internet channel can also be ensured by Internet server control.

Routed corporate network with distributed Internet channels

Such a network automatically appears at the enterprise, which combines the local networks of its remote sites, renting channels from the Internet provider, i.e. building a so-called virtual private network. Except that each office can get its own Internet access, this scheme does not differ from the previous one. By concluding an agreement with a provider for a dedicated line, the client, as a rule, can choose whether this channel will be routed to the Internet or not. However, often from a topological point of view, it will be more profitable not to drive Internet traffic to one central office, but to get Internet access in each office. How, then, to make the Internet access public, and not fragmented and uncontrollable?

You can also solve this problem using the set of Internet control servers in each office, where there is an independent Internet channel. For the administrator of such a network, managing Internet access from all offices in this case will be transparent and convenient.

Thus, the optimal solution to the problem of setting up controlled shared Internet access in all cases will be the use of an Internet server control — one, in the case of one local network, or a single Internet channel and several if Internet channels are available at geographically remote points of the company’s network.

Sharing settings

On the example of using A-Real Internet control server development company A-Real Consulting.

Shared Internet in a local network with one Internet channel

Initial conditions: ADSL line from the provider, ADSL modem broadcasts the WAN interface of the ADSL modem. Inside the local network, “gray” addressing is used, for example 10.0.1.0/24.

To configure general Internet access, you must enable the internal A-Real Internet server control interface in the LAN switch port. On the internal interface of A-Real Internet server control, set the IP address and mask of your local network, for example, 10.0.1.254/24. On the external interface of A-Real Internet server control and the LAN interface of the ADSL modem, set the "gray" addresses from a different range, for example 10.0.255.1/24 and 10.0.255.255/24, respectively.

Further, if a proxy server is used in your network, you can transfer its task to the built-in proxy server A-Real Internet server control. To do this, simply configure the proxy server address on the browsers of computers on the local network: 10.0.1.254 port 3128.

• For example, by clearly linking users to computers, you can configure the simplest scheme on A-Real Internet Control Server - by IP addresses. Naturally, in this case, it is necessary to take measures so that users cannot change their IP addresses themselves, for example, not to give them administrative access to computers.
• Login on a proxy server. You can give users individual logins and passwords to access Internet resources through a proxy server.
• Login through a windows domain controller. A-Real Internet control server can receive information about the user from the Active Directory domain controller, in this case, the user only needs to go to the windows domain with his password in order to gain general access to the Internet through the A-Real Internet control server.
• Login through a separate program. If the use of a domain controller is not included in your plans, you can install a small program on users' computers, which is included in the delivery package of A-Real Internet server control, which will ask for the username and password of the user when he accesses the Internet.
• Login through PPTP or PPPoE. You can configure a PPPoE or PPTP server on the Internet server so that users can access the Internet through a VPN tunnel, which each computer must install with an Internet server control - each with its own username and password.

Shared Internet access through A-Real Internet control server

A-Real Internet control server is a ready-made software Internet gateway. It is installed on a dedicated computer connected between the local network and the Internet. A-Real

When setting up a laptop or computer to distribute the Internet via Wi-Fi on Windows 10, some users cannot provide shared access to the Internet network. In this article we will try to provide information on how to open shared access to a Wi-Fi network, what difficulties may arise in this case and how to solve them.

The wireless data transfer function is very popular among network users. This process is carried out mainly using a Wi-Fi router. But sometimes it is not there or it is simply impossible to use it for some reason. In such situations, you need to know how to create an access point from a simple Wi-Fi adapter. Having configured the Internet distribution in the access point mode, it is not always possible to use the Internet, even when connected to the created network. This happens mainly due to standard settings that do not allow the use of the connection on connected devices.

The work of the virtual Wi-Fi module in the tenth version of Windows is similar to the seven. Organization of a wireless network without a router should assume the presence of WiFi technology, which is equipped with an adapter. This module is installed not only in routers and modems, but also in phones, tablets, laptops. As a result, the device can act as an access point. The launch of the access point is organized using the command line. After that, you can receive and distribute the Internet at the same time, but there is one problem - the network is turned on, but you cannot receive and transmit traffic to the Internet. This is because you want to enable this sharing. How to fix it? To do this, you need to know the connection with which the Internet is provided, by opening the general access to it for the Wi-Fi module.

This article is a supplement to the instructions on. Therefore, if you did not do this, then it is better to start by installing everything according to the instructions. And if you have already created a Wi-Fi access point, but connecting to it leads to limited traffic transfer or to its absence at all, then this is connected with some difficulties that can be quickly solved. Let's try to deal sequentially with the problems that happen in the sharing settings for the Wi-Fi network module in Windows 10 and how to solve them.

When you open a shared access to the Internet network not offered to choose a connection

A similar problem happens quite often. Its essence lies in the fact that when you start the Internet access point, in the window with the adapters there is already “ Local Area Connection 12"(The name can include any number) and now it remains to allow an Internet connection for this particular network.

• For you need to go into the connection properties: by clicking on the Internet network connection icon (on the desktop bottom right), right-click, select " Network Management Center ..«.

• And then open the section " Change adapter settings". Here you need to click on the network icon (most often " Ethernet") Right click on" The properties"And then open the tab" Access"And activate the line" Allow other users to use... .. ". But what if the lines " Home network connection" no? Only “ Wireless network“Because the menu does not drop out, in which the connection we need should be. In fact, it looks like this:

• There is an exit. To do this, open the properties of the adapter with which the network is connected. Then from the line “ Allow connected network users to use the Internet ..."Remove the mark, and press" OK«.

• Then re-enter the adapter properties and return the checkmark to its place. After that, a menu will open at the bottom, in which we will have the “ Local Area Connection 12"(May be different). Then activate it with the button “ OK«.

• The method of disconnecting and turning on the network adapter also works. To do this, click on the connection icon and select " Disable". After that, restart.

The done manipulations should lead to the appearance of Internet access on the provided network for other devices.

If, nevertheless, the selection line for the home network still does not appear in the drop-down menu, then you need to check that the Internet is really running, in the “Adapters Settings” there should be a network icon “Local Area Connection (in our case 12)” with the image network.

No access tab   in connection properties in Windows 10

To provide shared access, you must set the parameter in the Internet properties, but there is no tab “For this purpose” Access«.

  To correct the situation you need to do the following:

1. First you need to check for the presence of the " LAN connection* ". This can be done by opening " Network and Internet", Then" Network connections". If there is an icon, then the network is running. Otherwise, you need to activate it using the above instructions.
2. If only the “ Ethernet", Then the tabs" access "and there will be no choice of connections to networks, because all connections are missing. A solution to this problem could be installing the driver on a virtual adapter and starting it. If there is more than one network connection, then you need to install the driver and start it again.
3. There are times when a check mark is selected to allow other users opposite the “ Wireless network"In the properties of other connections, then you need to remove it and most likely the item" Access" at " Ethernet"Will appear.
4. If you have the “Starter” version of Windows 7 installed, then you will not be able to share.
5. When setting up the provision of Internet with a 3G modem, it happens that the item “ Access" missing. This is due precisely to the model of the modem itself and its settings.

Question: Internet connection sharing cannot be enabled. LAN connection is already configured to use

   Internet connection sharing cannot be enabled. The LAN connection is already configured to use the IP address necessary for automatic IP addressing .... What should I do ?? I need to create shared access from the first connection to the second I can not .... Thank you in advance for your help ...

Answer: Runner0910,
  your provider (probably intentionally) distributes IP in the same range 192.168.137. *, in which Vin usually assigns an address when "sharing".
  You need to disconnect from the Internet, then share "Local Area Connection" to "Local Area Connection 2", then go to the TCP / IPv4 properties "Local Area Connection 2" and change 192.168.137.1 to 192.168.0.1,
  then connect the internet

Question: Internet sharing does not turn on

   Good afternoon!

For the second or third day I can’t turn on Internet sharing for Virtual WiFi. The bottom line is that a window pops up with a warning that sharing is already used for "ethernet_14". What is this ethernet_14, I have no idea. Then a window appears that the new parameters will be applied the next time you connect, and then a window with an error.

Answer: insect_87, windows was updated, and this problem disappeared. But there was a trouble with COM Surrogate. I turn on shared access - on the laptop from which I am distributing it, it says that there is Internet, on devices (smart on WM10 and a tablet on Android) it says that there is no Internet. I’m trying to turn off sharing so I can try turning it on again, it says “COM Surrogate has stopped working,” then the “Unexpected error occurred” window and the “Network Connections” window hangs tight.

In general, the conclusion: Windows 10 is not ready to distribute the Internet so easily.

Question: Sharing Internet access on 2 interfaces simultaneously (lan + wlan)

   By certain manipulations, it was possible to create a virtual access point on win7 from a wlan card. Is it possible by standard Windows tools to provide two interfaces with Internet access? One of which is LAN, the other is WLAN. They are not added to the bridge.
  Ps: If you don’t bother with Windows, what program do you recommend for this task?

Answer:

Quote Noel:

I'm afraid not.
  But, as far as I remember, it easily does.
  Enough free version.

Question: There is no access to the server via external ip through the local network

   I have two databases on different territories. The first is data entry and processing, and the second is where users work. Weekly, the second database needs to be updated. The network is excluded. Vrodeba Replication must solve this problem, but how to do it and where to read about it in Russian. Maybe there are ready-made scripts for replication.

Answer:   And actually it all worked, but through one place known to everyone ... So, next to the server there is a computer on it, a constant server ping is launched and it displays "the timeout period has been exceeded", in general, it does not work. At this moment, a copy of the existing Internet connection is created on the server and .... PING and all access via the external IP appear. At the same time, the connection is stupidly copied with the "create copy" button, it is not connected and is not configured, just a copy of the existing one is simply banal and stupid.

From this moment everything works. I looked at the difference in routes when creating a copy - it is not there. So how to leave this state of things, because a reboot kills access again ... even if there are no special options, can there be some kind of command to create / remove a connection from the command line? I know there is a connection, because I use it, but creating / deleting ...

Until now, I don’t catch what the joke is ... even Windows rearranged and reconfigured to a minimum, but still the same canoe.

Question: How to configure the Internet and local area network on a Windows Server 2008 r2 server

   Good day, dear forum users.
  I appeal to you for help.

Question: How to organize Internet sharing

   Hello everybody. At my workplace, where there are more than 100 computers on the network, there is no Internet connection. My colleagues and I decided to buy a USB modem and organize access to the Internet through it. After scouring the net, I found instructions on how to do this. However, following a variety of instructions, I ran into problems. Below about them.

About networking, I can say that the address type of our computers says "Assigned DHCP". I installed the modem on my computer. Also, according to the instructions, I created a new connection. As a result, my computer began to go online, however, at the same time I lost the ability to go to shared network folders, and my email also stopped working. When you disconnect the Internet connection, everything works again.

Thus, I cannot normally (without disrupting access to the internal network) access the Internet on the computer on which the modem is installed. Therefore, while I have a question, is it possible in my situation to organize access to the Internet without disrupting access to the network?

P.S. If I did not provide enough data for the answer, then write about it, because I do not know what might be needed for the solution.

Answer:

Additionally, on your computer (so that it becomes a router):
  1. start the "Routing and Remote Access" service, the startup mode is "Auto"
  2. in the registry branch HKEY_LOCAL_MACHINE \\ SYSTEM \\ CurrentControlSet \\ Services \\ Tcpip \\ Parameters
  set IPEnableRouter to 1

Question: General access to the Internet (an RNDIS device was connected to a computer in LAN)

   Hello.
  There is a local office network of several PCs with a router ( 192.168.0 .1 ) To one of the PCs (with Win XP SP3) of this LAN on uSB cable   connected device using rNDIS drivers   (I don’t understand what it is). The bottom line is - when I turn on the device, on this PC in network connections   a new connection appears, associated with RNDIS (I will call it NDIS1). This PC has Internet access through a “LAN connection” (via a router).
  Automatically IP address NDIS1 can not get. I install IPD type for NDIS1 in TCP / IP 192.168.1 .1 . (note - another subnet, why - I will say below). For devices   in its internal network settings I prescribe a subnet mask of 255.255.255.0, a gateway 192.168.1 .1 DNS 192.168.1 .1 The static IP for the device is valid 192.168. 1 .9. Now in the office subnet 192.168.0 .*   This device has become available by its IP. But this device does not have Internet access.
How can I configure a "local area connection" on this PC so that NDIS1 can also go online using a "local area connection". If I put a daw in the "Local Area Connection" - Allow access to other users - a message is displayed - "When the general access to the Internet connection is enabled, the LAN network card will be assigned IP 192.168.0.1. In this case, communication with network computers can be lost "... If you click YES, then the message" unable to allow general access to the Internet connection. The connection on the LAN is already configured to use ip, which is distributed automatically. "
  What to do then?
  Thank.

P.S. Why I give ip to another subnet: if you give IP from the office network, NDIS1 will get IP, but the device will not be "visible" in the office network. And why - HZ.

Answer:   Sekns, he would not doper, reasonably logical. I will test
