Windows 10: 5ghz WiFi just stopped working.

So I have a dual band router and my son’s desktop connects wirelessly to the 5ghz signal usually. This morning it was connected but nothing loads through his browser and no apps connect. I switch him to the 2.4ghz connection and everything works no issues. When I reboot the computer, if I open a web browser straight away it works for about 10 seconds loading a website then stops working. It says it is still connected to the network but nothing loads. Any advice? I tried using different DNS server, flushing dns settings, updating drivers for the WiFi adaptor. Nothing seems to help.

5ghz wifi not showing windows 10

I just got a new modem/router and it has a 2.4ghz and 5ghz wifi connections...Only the 2.4ghz shows in the wifi list while the 5ghz isn't showing at all. My computer's network card does support the 5ghz and I know the 5ghz is working because I can connect to it from other devices...just not my desktop computer.

EDIT: I've attempted updating network driver, also resetting network in the settings menu. Both hasn't worked.

5GHz Wifi no longer showing

Hello,

I own the Hp spectre x360 ac-002ne. Previously my laptop was able to connect to my 5GHz wifi. Suddenly the 5GHz network disappeared on the laptop, but it is sill showing on other devices. The 2.4 GHz wifi is still working on the laptop. I tried uninstalling
the wifi drivers, reinstalling them and even doing a system restore point but neither one of them solved the issue.

Any suggestion?

Thank you
