Linux: Setting up the Realtek RTL88x2bu WLAN adapter

Realtek WLAN adapter is not recognised in Linux Mint.

Linux and the dear drivers. I currently had the problem that my USB WLAN adapter was not recognised under Linux Mint. “lsusb” at least showed that it was connected.

Bus 003 Device 002: ID 0bda:b812 Realtek Semiconductor Corp. RTL88x2bu [AC1200 Techkey]

However, the driver is probably missing here. Fortunately, this can be installed in a few simple steps:

sudo git clone "" /usr/src/rtl88x2bu-git
sudo sed -i 's/PACKAGE_VERSION="@PKGVER@"/PACKAGE_VERSION="git"/g' /usr/src/rtl88x2bu-git/dkms.conf
sudo dkms add -m rtl88x2bu -v git
sudo dkms autoinstall

After restarting the system, the adapter worked and the WLAN networks were displayed.
