I do a lot of traveling and my Macbook has always done fine in the hotels and connecting to there wireless systems. When I got back the other day my mac wont pick up anything for a signal in my own home. If I plug it in directly it works like a champ. Im thinking something happened with my settings. When I try to connect to my default (home) wireless it asks me for a WEP password. I dont remember setting one up and every password I try wont work. Any Ideas?
