Hi all,
Some more configuration hacking lead to success at 5 GHz!
My router supports 160 MHz channels in the 5 GHz bands [1]. I switched
the router to advertising 80 MHz channels and the card could connect.
--Justin
[1] Other cards, namely the iwlwifi-based Killer AX1650 that came in the
Dell XPS 13 9300 would use the whole 160 MHz channel with no problem!
I'm kinda bummed that the XPS 13 9310 comes with card that can only use
80 MHz channels. :-(
