Bug Description
Hi,
I have a Dell Vostro 3700 notebook running Ubuntu 12.04.1 LTS and a Netgear FWG114P WLAN router which I bought 2005.
Since the update on Sunday 27. January 2013 the NetworkManager fails to connect to my WLAN Router.
The Indicator applet shows all available wireless networks, but the NetworkManager fails to establish the connection. Due to the fact that I see the available networks I think the WLAN driver itself works fine. It seems to be a DHCP problem, but I have no idead how to solve it.
If I boot from an Ubuntu 12.04 USB stick which I created about 1 year ago WLAN works fine. Thus it's not a hardware problem.
Please could you give me some hints how to solve this problem.
Thanks & Best regards,
Franz Hollerer
