  • drivers need to be compiled to the kernel you are using. you might be able to find a precompiled one (may give the same performance as the generic one), but normally you download the source and compile it (this gives the best results). it is possible that you could download the sourse from windows – ravery Jul 12 '17 at 6:56

Please implement the fix outlined here: Ubuntu GNOME 17.04: wi-fi not working -- mac address keeps changing?

Next, please check to see if two possibly conflicting drivers are loaded:

lsmod | grep rtl

If you find that both rtl8192cu and rtl8xxxu are loaded, then blacklist one:

sudo -i
echo "blacklist rtl8192cu"  >>  /etc/modprobe.d/blacklist.conf
exit

After making these two changes, reboot and let us hear the result.
