Windows 11 - WiFi 5GHz - Unable to connect to this Network

[RedViking]

Used to work on Windows 10. Can't connect to 5GHz, only 2.4GHz.
Maybe once a day it will allow me to connect to the 5G. I am sitting next to the router.

Sure you can try and force only 5GHz connection on that menu.

Tried that. Get the same message.

Don't fret, Windows 12 will fix all that.

Change the channel on the router.

It's because you have 802.11 ANC mode on.

Have you tried rebooting?

 

[RedViking]

Change the channel on the router.

Nope. Still not.

 

[backstreetboy]

Nope. Still not.

Try changing the channel width?

PC and router and network adaptor. Yes. Thank you. Nothing.

 

[backstreetboy]

Nope. Still not.

There not a driver update?

Nope. Latest drivers.

Nope. Latest drivers.

Even if you use something like this https://www.glenn.delahoy.com/snappy-driver-installer-origin/

Edit: Replaced link with original one.

Do you have another access point you can test with so you can narrow down if the issue is with the router or the client?

I can connect to the 2.4GHz on the router. I tried on another similar router. It connected once and then when tried to connect again, "Unable to Connect to this Network".

It connected earlier after a couple of failed attempts. But then when I tried to connect again now "Unable to connect to this network".

It didn't have this issue on Windows 10, only time it didn't connect then was when the signal was weak.

I can try, but I prefer to go with the official Dell Drivers.

Sounds dumb but you didn’t have mac filtering on on your 5ghz network? Have you tried utilising the real mac address?

 

[RedViking]

I connected easily with my phone to the 5G network. No issues.

I don't think so. But can check. Everything is set on Auto.
