Proper way of installing wifi drivers (rtl8822bu)

  • 772

I have troubles installing drivers for my TP-LINK Archer T3U on Ubuntu 18.04.

Having found out the device ID 2357:012d, I used this repo by @Jeremy31.

Namely, I downloaded the content, cd'ed into it, did make and make install.

What to do next?

sudo dkms add ./rtl8822bu

gives

Error! Could not find module source directory.
Directory: /usr/src/.-rtl8822bu does not exist.

How to properly install the driver?

  1. As I am running kernel 5.3.4 in Ubuntu MATE 19.04, for me it was the drivers from Cilynx's GitHub repo for RTL88x2BU that worked out OK.

    As detailed in the repo, I've installed the drivers using DKMS installation method:

    git clone https://github.com/cilynx/rtl88x2bu.git
cd rtl88x2bu
VER=$(sed -n 's/\PACKAGE_VERSION="\(.*\)"/\1/p' dkms.conf)
sudo rsync -rvhP ./ /usr/src/rtl88x2bu-${VER}
sudo dkms add -m rtl88x2bu -v ${VER}
sudo dkms build -m rtl88x2bu -v ${VER}
sudo dkms install -m rtl88x2bu -v ${VER}
sudo modprobe 88x2bu

    Since you are in the rtl8822bu directory, try

    sudo dkms add .
sudo dkms install 8822bu/1.1

  3. I had the same issue as you and I did as Jeremy 31 suggests in his answer. But even after all that lshw -C network didn't list the TP-LINK adapter, like nothing happened. What finally worked for me was switching the secure boot back on.

    I am running Ubuntu 18.04 on a 5.4.0-42-generic kernel.
