I've got an ASUS AX3000 (Intel AX200) Wireless Card but yesterday it has stopped working on 5GHZ band.
I note there was a recent driver update which is making me suspicious, but I have tried everything, read a million and one posts on here (yes, I've tried setting channel band to 20mhz) but nothing is working in terms of getting this card working properly again.
When I select 5ghz and insert the password, it shows secured connected in WIN 11 but I can't open any pages and everything times out, If I switch to 2.4ghz, works perfectly fine.
I've deleted drivers, I've uninstalled, I've tried windows drivers, I've tried intel drivers and I've tried taking the OEM Asus Driver and installing that. Still nothing.
I'm connecting to an ASUS XD6 ZenWifi Router.
Any other suggestions?
Rolled back driver to microsoft version, deleting all old drivers as I went.
Installed latest driver from fresh. Didn't fix it.
Then: Hard Reset and Set up from Scratch Zen Wifi XD6.
What a nightmare, but now fixed.
