    Cool Gutsy wireless connectivity

    I have been trying to get the wireless card working on my wifes laptop without any success. It's a Lenovo 3000 n100. I tried following the documentation on the ubuntu website at
    but it didn't fix the problem. The results of these efforts are below. I tried everything with the network cable out, just to avoid any confustion. I also tried looking at the associated forum entries which were suggested at the top as I started to compose this thread. Any help would be most appreciated.

    $ sudo lshw -C network

    Re: Gutsy wireless connectivity

    Have you installed wpasupplicant? I see you have a 169.254 IP address. Is WPA enabled on your AP?

    From the Terminal enter the command: sudo dhclient eth1

    That should help.
