I am having problems with my specific wireless connection. My computer can pick up other signals okay, and my roommates new Macbook picks up my signal fine. But when I try to connect to MY internet at the house (I am using a Belkin router) wirelessly, it won't connect. it tries for 2 seconds and then says "connection timeout". my time and dates are correct. this happened for no reason and no settings have been changed. whats going wrong?
