SUSE has detected my wireless card and I can connect to the internet by an unmanaged network with no cryption, but once I transfer to a managed network, my machine cannot get an IP through DHCP though it has found the wireless network.

I do not know what is wrong. Could u give me some guidance to solve it? My wireless card is Intel(R) PRO/wireless 2200BG network. Thank you very much.

And also I have another question about the displayer. The screen size is 1048X768 (the highest one in SUSE) in SUSE, which is different in WIndows. So I think it should have something to do with the driver. So could u also give me some advice to change the size of the screen.
