Can't connect to wifi on elementary Luna
I have the following problem with my fresh install of elementary (and basically every ubuntu-based distro from 12.04 onwards)
When connecting to my home wifi router, network manager asks for password then tries to connect, but I only see the indicator working that it is connecting, but nothing happens, I can only use the internet via cable. The problem occurs on every distro based on ubuntu from 12.04. After a while network manager stops trying and says wireless disconnected then tries again. (no problem however with the same computer on win Xp and ubuntu 10.04)
It is an IBM ThinkPad T43 laptop with broadcom wifi-card.
Thank you for your help in advance!
