I had to reinstall Ubuntu due to it failing to boot (stuck on /dev/sda1 clean ...).



Now for some strange reason it won't connect to my WiFi at home (same router as before), although the connection worked during the reinstallation. I tried with another WiFi from a phone hotspot and it worked with no problems...

It seems like the problem lies with DHCP, if I manually assign a static IP it works...strange. And I can connect to any other WiFi except this one.

Restart nework manager :



sudo service network-manager restart

  • The only correct statement in the link you posted is "The result is that those USB WiFi adapters cannot connect anymore to the WiFi network" and that only applied to 17.04. I have no idea who wrote that but it could have been a lot better. I don't understand why they wouldn't have used a dkms install for the rtl8188eu at the bottom as my github was mentioned and it does have dkms support.
