Hi @mefys Have you plugged in the two antenna onto the card (if not do so first and recheck) - appreciate this may seem obvious but lots of people forget to do so
Are you perhaps too far away from your router to get 5Ghz signal? You can easily check by moving the PC closer and seeing if it can connect to the 5Ghz band.
Can you confirm for sure you're 5GHz band is on and active from your router?
Excellent, glad its working!Seems to have done the trick. Thank you
