I resently got a rock 3a and got the a3 wifi module and I have not been able to get it to work. Any time I try to connet to wifi it says Error: No Wi-Fi device found. even though the cards light is on.
Wifi card is not working
What chipset does the wifi card have?
You need to install its drivers first.
Try like this:
apt-get update -y
apt-get install -y broadcom-wifibt-firmware intel-wifibt-firmware firmware-atheros
lsusb or lspci and you should find your wifi
I tryed this suggestion and got told cant locate software 5.10kernal
