Ubuntu – Installing edimax 7811 uac


I installed the following driver for an external wireless usb adapter from this page:


But the adapter is still unrecognized. How do I get it to be recognized?

The driver is rt2800usb

Bus 002 Device 010: ID 7392:a812 Edimax Technology Co., Ltd

uname -r

Best Answer

I compiled the version you built and it doesn't cover your exact device, 7392:a812. I suggest you remove it:

cd rtl8812AU
sudo make uninstall

Next, to avoid any confusion in the future, remove it entirely:

cd ..
rm -rf rtl8812AU

Now, let's build a correct driver:

sudo apt update
sudo apt install git
git clone https://github.com/gnab/rtl8812au.git
sudo dkms add ./rtl8812au 
sudo dkms build -m rtl8812au -v 4.2.2
sudo dkms install -m rtl8812au -v 4.2.2

Reboot and tell us if your wireless is working.

You may be required to turn off Secure Boot in the UEFI or BIOS.
