I am having trouble with this wifi card as well and reseating the connections didn’t work or a factory reset. I’m running it as 2.4ghz and discovered having a guest network on it was causing problems. No guest network and so far it’s running fine.
If you’re having trouble, go into guest networks on Forris and turn it off and reboot. You can then turn a guest network back on for the other card.
I also noticed the top plate really pushes down on the wifi card where the antennas get plugged ion. I’d like to sand down that top plate some, but don’t want to ruin a warranty.
