I did some more experiments: If wired network is plugged in, then suddenly the machine is able to complete also wifi connections. It does not matter whether the wired network remains plugged or not before trying the wifi connection. A single wired connection enables also wifi connections until the notebook is rebooted.
good luck with this funny bug. please solve it soon: wifi failure is a very good reason for changing operating system. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1246670 Title: ubuntu 12.04.3 LTS: can't connect to WIFI - protocol implementation problem??
