So i setup my desktop to broadcast an ad-hoc in my home as i don't have a wireless router. I can connect to that just fine w my 6700, but when i go to a resturant or bar or coffee house that has wifi i can never seem to connect. I'm just using the stock wifi network card program to look at the networks. I can see them and it will say connecting but no matter what it never connects to anything but my ad-hoc connection at my house. Anyone have any clue as to what the deal is?

WEP is on.
