I am new to Ubuntu, using 16.04.

I installed the tl-wn822n v4 adapter following How to install TP link WN822N on Ubuntu? but the problem is that after I restart the computer, the wifi adapter is no longer recognised.

I have to run the following commands to make it work (if I don't want to unplug/replug).

sudo modprobe -r 8192eu
sudo modprobe 8192eu

I added the commands to /etc/rc.local but it still does not work after a restart. As of now, the only way is to run the commands manually or physically unplug/replug the adapter.

Is there a better way to fix it?

  • What happens if you run only sudo modprobe 8192eu? – Pilot6 Feb 22 '17 at 17:12
  • nothing happens. -r is needed first. – Archer Lawless Feb 22 '17 at 17:57

    Can you uninstall that driver by sudo make uninstall from the source directory and install this deb https://launchpad.net/~hanipouspilot/+archive/ubuntu/rtlwifi/+files/rtl8192eu-dkms_4.4_all.deb – Pilot6 Feb 22 '17 at 17:59
  • Just tried uninstall and installed the rtl8192eu-dkms_4.4_all.deb. Restarted the computer and it's working! Just to be sure, I did a shutdown and startup of the computer.....not working. I still have to unplug/replug for it to work. – Archer Lawless Feb 23 '17 at 00:07
  • I updated the /etc/rc.local with the following and it finally works.

    modprobe -r 8192eu modprobe 8192eu sleep 5
