I upgraded to 17.04 but having some issue with wifi, how can I downgrade to 16.04?

  • Have you managed to run a full sudo apt update && sudo apt full-upgrade? That fixes at least one of the 17.04 image WiFi bugs. The other one is this one

You cannot downgrade the ubuntu version. You'll have to reinstall 16.04. The only solution is to re-install Ubuntu 16.04 and erase 17.04, so that you have a clean installation.

Just backup your relevant files, and run the installation CD/DVD/USB.

Erase Ubuntu 17.04 and install 16.04.
