How to fix can't connect to network on Windows

Question

Hi,
I am using an external Wi-Fi adapter (TP-Link Archer T2U) with the correct drivers to connect to a Wi-Fi network from my PC.

I am trying to connect to a 5Ghz network which the adapter supports but it can't seem to connect to it.
I have tried connecting to this network using the same adapter from a different PC and it connected just fine but when I try to connect back from my PC, it doesn't seem to work.

I have even performed a network reset on this PC but it still doesn't manage to connect.

Hello there,

Have you checked the Event Viewer for any trace?

If you cannot find anything in Event Viewer I would suggest you use tools like Procmon to find the root cause for this behaviour.

Have you made any recent updates that you are aware of on this device? If so try uninstalling them and check if this sorts out the issue

Try running these network commands to manually reset the TCP/IP stack, release and renew the IP address, and flush and reset the DNS client resolver cache:

At the command prompt, run the following commands in the listed order, and then check to see if that fixes your connection problem:

Type netsh winsock reset and select Enter.

Type netsh int ip reset and select Enter.

Type ipconfig /release and select Enter.

Type ipconfig /renew and select Enter.

Type ipconfig /flushdns and select Enter.

Hope this resolves your Query !!
