When encountering "Unidentified Network" and there is no network access permission, you can troubleshoot and solve the problem by following the following methods: 1. Check whether the router is normal, whether other devices can access the Internet, and whether the network cable is plugged in; 2. Run the command prompt as an administrator and enter netsh winsock reset and netsh int ip reset to reset the network components and restart the computer; 3. Set the IP address to automatically obtain IP and DNS; 4. Update or uninstall the reinstallation of the network driver; 5. Turn off the firewall or third-party security software to test whether to recover. Most of the problems can be solved through the above steps.

Encountering "Unidentified Network" and without network access is one of the common network problems in Windows systems. This situation usually occurs when a Wi-Fi or network cable is connected, but the computer cannot access the Internet and displays "No Internet access" or "Unidentified Network" on the taskbar. Don't worry, the following methods can help you quickly troubleshoot and solve this problem.

1. Check the basic connection: Make sure the network itself is fine

Sometimes the problem is not on the computer, but at the source of the network. Check the following points first:

• Is the router powered up normally and the indicator light flashed normally
• Can other devices (such as mobile phones and tablets) on the same network be able to access the Internet normally?
• If it is a wired connection, is the network cable plugged in or is it damaged?

If other devices do not have a network, it is a router or broadband problem. You can try restarting the router or contacting the network service provider.

2. Restart the network adapter and services

Sometimes Windows' network components will get stuck, and restarting related services or adapters can often solve the problem.

The operation steps are as follows:

• Open Command Prompt (run as administrator)
• Enter the following three commands, press Enter for each input:

 netsh winsock reset
netsh int ip reset

These two commands will reset the TCP/IP protocol stack and Winsock directory, which is very effective in repairing network exceptions.

After completion, restart the computer and see if the network is restored.

3. Set the IP address to automatic acquisition (DHCP)

If the IP address is set incorrectly, it will also lead to the inability to identify the network and obtain Internet access.

Operation steps:

• Right-click the network icon in the taskbar → “Open Network and Internet Settings”
• Click the currently connected network → View properties → Click "Internet Protocol Version 4 (TCP/IPv4)" → Properties
• Make sure that the selected one is:
  • Automatically obtain IP address
  • Automatically obtain DNS server address

If not, change to the above settings and close the window to try to see if the network is back to normal.

4. Update or reinstall the network driver

Outdated, corrupted or incompatible network drivers can also cause "unidentified networks" problems.

Operation suggestions:

• Press Win X → Device Manager → Expand Network Adapter
• Right-click your wireless or Ethernet adapter → Update driver
• If the update is invalid, you can try right-clicking to uninstall the device (check Delete Driver), and then restart the computer and let the system automatically reinstall the driver

If you are not sure which driver to use, you can directly download the latest network driver from the motherboard or laptop brand official website.

5. Check the firewall or third-party security software

Some firewalls or antivirus software may block certain network access behaviors, especially enterprise-grade software or recently installed security tools.

Try temporarily closing these software to see if the network is restored. If it is restored, you need to adjust the rules of the software or replace a security solution with better compatibility.

Basically, these common reasons and solutions are all about them. Although this problem is annoying, it is not a big problem most of the time. Follow the above method to check it step by step and it should be solved.
