No wifi-adapter found in gnome-control-center?

The USB wifi adapter appears here:

$ lsusb | grep TP
Bus 001 Device 002: ID 2357:010e TP-Link TL-WN722N v2

I had this working before an upgrade to 19.10. I've tried reinstalling the drivers but have not yet been able to get this working yet.

$ cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
    dns-nameservers 192.168.1.1

What are my next steps? I've been going through a lot of the old debug posts but nothing has worked yet.

$ iwconfig
docker0   no wireless extensions.

lo        no wireless extensions.

br-3ce68697cec1  no wireless extensions.

enp3s0    no wireless extensions.

And I guess if there are any known issues where you need to disconnect the wired connection to even test wifi that would be important to know.

Solution 1:

The correct driver for your V2 device 2357:010e is rtl8812au. The module aliases for 8188eu do not include your device.

Please do:

git clone https://github.com/gnab/rtl8812au.git
cd rtl8812au
sudo rsync -rvhP ./ /usr/src/8812au-4.2.2
sudo dkms add -m 8812au -v 4.2.2
sudo dkms build -m 8812au -v 4.2.2
sudo dkms install -m 8812au -v 4.2.2
sudo modprobe 8812au

Your wireless should now be working.

Solution 2:

For your TP-Link TL-WN722N v2 (ID: 2357:010e), you could install wireless drivers from this GitHub repo: https://github.com/hanipouspilot/rtl8812au
