The network manager does not give me a list of wireless networks but just 1 from my neigbours. There is no drop-list to select a different. When i try to connect to it via "hidden network" it asks for my network-key but the wifi icon is still blinking like it is connecting. I never get it activated. It worked some days ago and before and all the way through Lucid beta and RCs. I am not sure if it broke with the release. A cable connection is also not working. My Windows 7 partition on the same machine connects without problems wireless and wired.
