I just grabbed a copy of linux, but I've never used wireless with it before, and I really want to install it permanently on my laptop (or just be able to use it when windows gets annoying =) )

The only problem I'm having is that when I try to connect using kwifi, it finds the adapter, finds my wireless network, but I'm not getting an IP adress assigned to me for some reason. Local IP as shown in kwifi is "unavailable". Is there somthing else I should be doing? please help >.<
