Help for help Vista computers are both IPV4 and IPV6 restricted, why? Hurry

Your home is Netcom's broadband, so do you dial up your own or router to access the Internet?

Very important information, not presented.

If it's your own dialing, there is a yellow exclamation mark, it doesn't matter, leave him alone.

If it's a router to surf the Internet, then you can't get on the Internet, but you say it's slow, that's one of the above situations.

I suggest you call ** telecom or Netcom and ask them to check the line. I suspect it's a telecom problem.

Of course, it is not excluded that there are also computer poisons congesting the network, so let's kill the virus.

You can change the MAC address to see.

1 Right-click the network connection icon in the lower right corner and select"Network and Sharing Center"

2 In the left panel of the Network & Sharing Center window, click"Manage network connections"

3 Right-click"Local connection" --"attributes"

4 If prompted for User Account Control, select Continue.

5 Select under Connections in Use"Configuration"

6 Click"Advanced"Options.

7 Modifications"Network address"The value is OK, note that it is 12 bits (you can write numbers and letters at will) 8 ok, and complete the physical address modification.

Desktop - Network - Right Click - Properties - (Left) Manage Network Connections - Local Connections - Properties - Find Internet Protocol IPv4, Properties - Automatically Get DNS Server, Try It, or Local Connections - Right Click to Fix It.

Just set your own IP address and DNS server.

First of all, you should call Netcom's customer service to ask!

In fact, many things can be solved directly by calling customer service!

It may be an IP conflict, or it cannot be linked to the router, so it is best to restart the router. Or unplug all other network cables and connect to just one computer.

1. When the win10 network connection is limited or a yellow exclamation mark appears, right-click the "Network Connection" icon in the taskbar and select "Network and Sharing Center" from its right-click menu.

3. At this time, the "Network Connection" window will open, right-click the "Network Restricted" connection, and select the "Disable" item from its right-click menu.

4. After the corresponding network connection icon is disabled, right-click the network connection again and select "Enable" from its right-click menu.

5. At this time, for "local connection", the IP address will be automatically obtained from the gateway and connected. For "Wireless Network", you need to click the "Network Connection" icon in the lower right corner of the taskbar, and click the "Connect" button from the open extension panel, and you will find that the network connection is normal.

6. Of course, there are many reasons that lead to the problem of "limited network connection" or "no permission to access the network".

When such problems occur, we need to check whether the router can connect to the Internet normally, and make sure that the "network connection is normal" in the router web management interface. Otherwise, you need to check the settings on the router side.

7. In addition, we can also use "360lsp repair tool" to fix network failures. Use this tool to fix the LSP protocol and solve the problem of not being able to access the Internet normally.

8. At the same time, with the help of the "360DNS optimization" tool, the optimal network DNS filtering function can be realized, so as to solve the problem of "network instability" or "unable to open web pages".

9. Of course, if you upgrade to win10 official version of the system, there is no normal Internet access, "limited network connection" or "no permission to access the network", it is recommended to use "driver life 6" to update or repair the network card driver.

Right-click the "Windows" button in the lower left corner of the desktop, and select "Computer Management" from its right-click menu.

11. From the opened "Computer Management" window, then "Services and Applications" - "Services", find the two service items "Wired Autoconfig" and "WLAN AutoConfig", make sure that these two service items are in normal operation, otherwise click the "Start This Service" button in the upper left corner to start this service.

Control Panel: Win+X, then press P Network & Internet Tethering Center Click on your wireless connection properties Security and click on 'Advanced Settings' In the pop-up advanced settings, you can see "Enable Federal Information Processing Standard (FIPS) compatibility (F) for this network.""Tick the front. That's it.

There is another kind that I don't know if I can solve the network restriction problem:

Press win+x and press a This is the command prompt, type netsh and press enter, then enter winhttp and press enter, enter import proxy source=ie and press enter. I don't know if I can help you.

3.Reinstall or update the NIC.

Ask a question broadband. Hello, I used the first method and still can't access the Internet It's Huawei's notebook Suddenly there is no way to connect, there is still a network but it can't be accessed.

Telecom networks don't yet support the IPv6 protocol, so you can ignore IPv6 access. As for IPv4, do you check if your cat is powered on? Is it normal?

Check Details in the figure to see whether the IP address is obtained. You must establish a dial-up connection in order to be able to access the Internet.

Win7 notebook Wi-Fi, limited access to the problem, my personal solution is:

1. Check from the control panel --- management tools --- services: whether the dhcp client service (dhcpclient) is disabled, if it is banned, it will be OK.

2. If 360 Security Guard is installed: check whether the DHCP client service (DHCPclient) is disabled from the advanced tools --- boot startup item management--- the system's built-in startup items, and if it is disabled, it will be OK. Because some startup items in 360 Security Guard have been optimized and closed.

The dial-up connection is deleted. Reinstall a dial-up connection. You can't change the network card again. It is possible that the NIC does not support WIM8

If you use an IPv4+ address, you can't use IPv6, first make sure that the router is set up correctly. 1. Computer IP address setting problem (1) When connecting to the router to surf the Internet, you need to set the IP address on the computer to automatically obtain (dynamic IP). Computer dynamic IP address configuration (2), if your network, the administrator requires a fixed IP address to access the Internet, please fill in the correct IP address, subnet mask, gateway and DNS server address in the local connection.

2. Check whether the network is normal. 1. First of all, open PC Manager and select the toolbox in the lower right corner. 2. Select the network repair tool.

3. Click to fix it immediately. The above is for reference, I hope it can help you. If my answer is helpful to you, please give a thumbs up (in the lower left corner), I look forward to your like, your efforts are very important to me, and your support is also the motivation for my progress.

Finally, I wish you good health and a good mood!

Hello! If there are no special needs or other reasons.

When making sure you are physically able to surf the Internet.

Set the virtual machine NIC to bridge mode.

Set the NIC IPv4 in the VM to automatic.

Generally, if the above two conditions are met, the virtual machine can access the Internet (of course, special networks, such as enterprise networks, have restrictions, that is another matter).

If it is set to a bridge, the virtual machine shows that the network cable is not connected or disconnected, generally VM0 is not working properly, and you can use the installation package to select the repair, or the virtual network to see if there is VM 0, and the default is not restored, but sometimes it seems that it can't solve the problem.

Hope it helps!
