Installation successful but no wifi
Hi, I have installed the driver without issues on Debian 11 Bullseye (5.10.0-30-amd64 x86_64). I have a usb stick that needs RTL8811A/RTL8821A USB drivers. However, after installing it wifi is sill not enabled. I have tried different ports but didn't make a difference.
Not sure if this issue is valid, as the driver installed correctly. The device is from an unknown brand (https://approx.es/producto/appusb600da-adaptador-usb-wifi-600mb-antena/) and they have linux drivers (software tab) but they are outdated, so I was not able to install them. However, it includes some documentation where it states that need RTL8811A/RTL8821A USB drivers.
Any recommendation on how to check whats wrong?
running lsusb -v gives me:
