I edited some files git and compiled it at Ubuntu 22.10 Use: install_t3uv3.sh to install it

In order to make direct use of the driver it should suffice to build the driver with make and to load it with insmod 88x2bu.ko. This will allow you to use the driver directly without changing your system persistently. It might happen that your system freezes instantaneously. Ensure to not loose important work by saving and such beforehand.

If you want to have the driver available at startup, it will be convenient to register it in DKMS. An executable explanation of how to do so can be found in the script deploy.sh. Since registering a kernel module in DKMS is a major intervention, only execute it if you understand what the script does.

Some users reported problems due to Unknown symbol in module. This can be caused by old deployments of the driver still being present in the systems directories. One solution reported was to forcefully remove all old driver modules:

sudo dkms remove rtl88x2bu/5.8.7.4 --all
find /lib/modules -name cfg80211.ko -ls
sudo rm -f /lib/modules/*/updates/net/wireless/cfg80211.ko
