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 https://help.ubuntu.com/7.10/internet/C/wireless.html 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.
