I have installed Debian 9 and everything looks great I'm just struggling to install my wifi adapters drivers. I have found the adapter driver here. I'm just very new to the console and need a bit of guidance in using it.

Per the installation guide:

  • Make sure your kernel is up to date: sudo apt-get dist-upgrade, then reboot.
  • Go to the folder where you downloaded the driver in a terminal (like cd ~/Downloads/wifidrv/).
  • Check your compiler version with cat /proc/version | grep "gcc version". The version number is after gcc version (which should be in red). If it is at least 5.4.0, you can continue.
  • Compile the driver with make clean and then make.
  • After the commands finish, you should see a .ko file in the directory (you can find the name with ls | grep ".ko".
  • Then, load the driver with the following:

    sudo cp 88x2bu.ko /lib/modules/[kernel version]/kernel/drivers/net/wireless/
    # Make sure to replace (above) [kernel version] with your current kernel version.
    sudo depmod -a
    sudo modprobe 88x2bu.ko

Make sure 88x2bu.ko is the wifi driver's name.

Then, check to see if the driver installed by running lsmod. If it didn't, reboot and try lsmod again.
