Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I read several forums and questions, and it seems that everyone have issues with wifi connections, since the last update of 13.04. I've got the same problem with the last kernel update in Fedora18, and for that I had to unistall it (sigh) and try Ubuntu, but it was the same. I tried almost every kind of solution, nothing worked for me.

Does anybody knows when the ubuntu team will solve this problem?

edit: wifi works fine in W7 and my galaxy tab2

Update: Info required

If you try running the command nmcli nm wifi on in the Terminal window that could help.
