Trên máy tính, nhất là các laptop sử dụng kết nối WiFi chúng ta thường gặp tình trạng lỗi WiFi bị Limited, giới hạn kết nối không vào được WiFi. Khi gặp lỗi này, các bạn sẽ không thể truy cập vào mạng WiFi đang kết nối, dù là đã nhập đúng mật khẩu. Người dùng muốn sửa lỗi Limited WiFi, giới hạn kết nối không vào được WiFi cần thay đổi địa chỉ IP hay thực hiện một số thao tác khác. Bởi lẽ trên từng WiFi nhất định mà thông số IP sẽ được cài đặt khác nhau, nếu là WiFi cài IP tĩnh, bạn cần nhập IP tĩnh để kết nối được mạng Internet. Còn với IP động thì cần chuyển về chế độ tự nhận IP động mà thôi. Một lỗi khác cũng liên quan đến IP mà đôi khi chúng ta gặp phải là lỗi "Ethernet doesn’t have a valid IP configuration" trên Window.

If you lose your internet connection, the Windows Network Diagnostics troubleshooter is usually helpful. However, sometimes you'll just see a vague error message like "Ethernet doesn't have a valid IP configuration," which doesn't give you much information about the problem. This error usually pops up when there's a problem when you're connected to the internet via Ethernet and your router can't assign your PC an IP address via DCHP. Fortunately, these fixes will get you back online in no time. This wikiHow article will walk you through fixing the "Ethernet doesn't have a valid IP configuration" error on your Windows 10 or 11 PC.

Things You Should Know

• The "Ethernet doesn't have a valid IP configuration" error appears in the Windows network troubleshooter when your PC cannot obtain an IP address.
• The problem is usually related to your TCP/IP settings, ethernet driver, or router.
• A properly configured router or switch could also lead to an invalid IP configuration.

1. If you just started seeing the "Ethernet doesn't have a valid IP configuration" error, you may be able to resolve it by rebooting your computer.

1. If you haven't tried to repair your connection when running the troubleshooter, follow these steps:
   • Type network troubleshooter into the Windows Search bar.
   • Click Identify and repair network problems or Find and fix network problems, depending on your Windows version.
   • Click Next and then Troubleshoot my connection to the internet.
   • Click Details about errors. If you still see "Ethernet doesn't have a valid IP configuration," continue with troubleshooting.

1. This includes your modem, router, and any switches you may be connected to. Disconnect the power cable and the ethernet cable from your router (and modem, if separate), and leave everything turned off for at least 30 seconds before reconnecting.
   • Once your router is back online and reconnected to your computer, try connecting to the internet again.
   • If you still can't connect, run the again to see if you're still getting the "Ethernet doesn't have a valid IP configuration" error.

1. The steps are the same whether you're using Windows 10 or 11:
   • Type network connections into the Windows Search bar.
   • Click View network connections.
   • Right-click your Ethernet adapter and click Disable.
   • Once disabled, right-click Ethernet again and select Enable.
   • Once enabled, start the network troubleshooter again.

1. To do this, type cmd into the Window Search bar, then click Command Prompt in the search results.
2. This releases the last IP address and displays several "disconnected" messages in the window.
3. Windows will request a new IP address from your router.
   • Once your IP address is renewed, you should see an IPv4 and/or an IPv6 address under your ethernet adapter.
   • If you see the error "This operation failed as no adapter is in the state permissible for this operation," you have configured a static IP address for your PC. If your IP address is supposed to be dynamically assigned by your router, you will need to and select "Obtain an IP address automatically."

1. Your PC may be trying to use a specific IP address instead of DHCP (or vice-versa). It's also possible that IPv6 is disabled, which many Windows users report causes this error. Here's where to look:
   • Type network connections into the Windows Search bar.
   • Click View network connections.
   • Right-click your Ethernet adapter and select Properties.
   • If the box next to "Internet Protocol Version 6 (TCP/IPv6)" is not checked, click the box to enable it now.
   • Select "Internet Protocol Version 6 (TCP/IPv6)" and click the Properties button.
   • Make sure "Obtain an IPv6 address automatically" is selected, and then click OK.
   • Select Internet Protocol Version 4 (TCP/IPv4) and click the Properties button.
   • Make sure "Obtain an IP address automatically" is selected.
     • If you are supposed to have a static IP address assigned by your router, verify that the IP address, subnet mask, and default gateway are correct. If this all sounds strange to you, just choose "Obtain an IP address automatically" instead.
   • Click OK and then click Close.
   • If you made any changes, restart your PC and restart your router.

1. If you're using Windows 11, you can open Terminal as an administrator instead if you prefer—either will work.
   • Type cmd or terminal into the Windows Search bar.
   • Right-click Command Prompt (or Terminal) and select Run as administrator.
   • Click Yes.
2. This resets TCP/IP by overwriting its registry keys.
3. You should see the message "Successfully reset the Winsock Catalog. You must restart the computer to complete the reset."
   • A quick way to reboot from Command Prompt is to type shutdown /r /t 0 and press Enter.

1. Once connected directly to the router, try running the internet troubleshooter again to see if you're still getting the "Ethernet doesn't have a valid IP configuration" error.
   • If you can connect to the internet directly through the router but not through the switch, your switch is likely cabled or misconfigured.

1. You can do this quickly by right-clicking the Start menu and selecting Device Manager.
   • If your computer is not currently connected to the internet, a default ethernet driver will be installed once you uninstall your current driver. However, it's better to use this method if you can connect to the internet, even if you have to head to a café or other location with Wi-Fi.
2. A list of network adapters will expand.
3. If prompted, click Uninstall to confirm. This removes the driver from your PC.
4. When Windows restarts, it will automatically install the best-fitting driver for the card.

1. This method will delete all your saved network settings, including any Wi-Fi passwords and VPN settings you've added. However, it may also resolve the "Ethernet doesn't have a valid IP configuration" error.
2. This opens your internet settings.
3. You can skip this step if you're using Windows 10.
4. If you're using Windows 10, it'll be a text link at the bottom of the right panel. On Windows 11, it's under the "More Settings" header.
5. This deletes your entire network configuration and replaces it with the default settings.
6. Now that your network settings are cleared, power down your router and disconnect the ethernet cable from your PC. After a few moments, turn the router back on, then plug the ethernet cable back in. Wait 3 to 4 minutes.

1. If you configured your router yourself, log in to it as an administrator and verify that DHCP is enabled. Or, if your router is set to assign your PC a specific static IP address, make sure the address it's assigning matches the one you've configured in .
   • If you got your router from your ISP and haven't changed any of its settings, try resetting it by inserting an extended paperclip or SIM tool into the small reset hole on its back side. After several minutes, the router will return to its default configuration.

If you can get online when connected to a different network, the problem is unrelated to your computer. Your router may need to be replaced. In this case, contact your ISP (if they issued your router), or contact the router manufacturer for instructions on replacement or repair.
