**solved*** unable to install usb wifi adapter

[emiliocb4]

hello all,
i've the following distro:
Linux nas 4.19.0-0.bpo.5-amd64 #1 SMP Debian 4.19.37-4~bpo9+1 (2019-06-19) x86_64 GNU/Linux

after a long time i've finally found a working driver (at least compiling and installing)
https://github.com/minjae/rtl8821au.git

i can see the usb device:
root@nas:~/rtl8821au# lsusb
Bus 001 Device 003: ID 0bda:b812 Realtek Semiconductor Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
but i can only see the ethernet interface

Have you changed the sources.list to add contrib and non-free?

I think that is the wrong driver for your device. Try this one - https://github.com/jeremyb31/rtl8822bu
And you may also need to install the package firmware-realtek from non-free repo.

This has got a bit beyond my pay grade so I hoped a network expert would weigh in. Couple of ideas though: what do you get with this command?

Code: Select all

su -
<enter root password>
rfkill list

Or if you have sudo set up:

Code: Select all

sudo 'rfkill list'

unfortunately no block are present:
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no

any other ideas?

Solved. The issue were related the gateway, because the wifi interface were unable to write its own route to the routing table. So i shutdown the eth interface and usinf only the wifi all works fine.

thanks
