Building module for other kernels

make KSRC=/lib/modules/YOUR_KERNEL_VERSION/build

sudo make uninstall

Manual DKMS installation

git clone "https://github.com/RinCat/RTL88x2BU-Linux-Driver.git" /usr/src/rtl88x2bu-git
sed -i 's/PACKAGE_VERSION="@PKGVER@"/PACKAGE_VERSION="git"/g' /usr/src/rtl88x2bu-git/dkms.conf
dkms add -m rtl88x2bu -v git
dkms autoinstall

USB 3.0 Support

You can try use modprobe 88x2bu rtw_switch_usb_mode=1 to force the adapter run under USB 3.0. But if your adapter/port/motherboard not support it, the driver will be in restart loop. Remove the parameter and reload the driver to restore. Alternatively, modprobe 88x2bu rtw_switch_usb_mode=2 let's it run as USB 2 device.

Notice: If you had already loaded the moduel, use modprobe -r 88x2bu to unload it first.

If you want to force a given mode permanently (even when switching the adapter across devices), create the file /etc/modprobe.d/99-RTL88x2BU.conf with the following content: options 88x2bu rtw_switch_usb_mode=1


Set debug log use echo 5 > /proc/net/rtl88x2bu/log_level or modprobe 88x2bu rtw_drv_log_level=5
