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 "https://github.com/RinCat/RTL88x2BU-Linux-Driver.git" /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.
