I'm trying to hook up my ThinkPad to my existing AirPort Express. The internet and iTunes connections work fine, but when I go to MacRumors Forums, it tells me that my IP Address has been banned. I'm now using the same ThinkPad at through a hotspot in a cafe, and it works fine. Right now I have set my AirPort Express for WEP at 128bit and MAC Address restrictions, but they shouldn't affect an IP Address problem. (My IP address when using the Airport starts with a 10.) Can some help? The MacRumors forum is the only place on the web I can't access from home!
