Hello,

I got a brand new XPS 15 9520 and I have some issues when I want to connect to 5ghz wifi. 

The router works perfectly and the new XPS is in the same place as my previous laptop (which works on 5ghz very well)

I tried to install the latest wifi driver, bios update etc but without luck. When trying to connect to my 5ghz wifi I get an error "can't connect to this network". And that's it. Nothing else happens. 

I saw that many XPSs had WIFI card problems. Could this be the same issue? 
Any ideas? Thanks!

 

PS: I have the AX211 network card.
