Hi,
since yesterday both my netbook and my laptop (running xubuntu 14.04 and Ubuntu 14.04, respectively) do not recognize my wireless signal anymore.
I have dual-boot on both systems (windows 7) and in windows the wireless is recognized flawlessly /therefore it is definitively NOT a hardware-problem).

What can have suddenly caused this? Anything wrong with the last ubuntu-updates? Anybody else who suddenly got this problem? Any Ideas on what I can do?
