I mean no offense at all to you but I'd be pissed off if someone was using my connection!! I pay for a certain speed and if someone else is stealing my connection it will take away a portion of my speed and in turn my hard earned money!!

On the other hand if your neighbor wasn't smart enough to use security from the start it must not have bothered them too much When you do get your connection working please please please set up security!! My husband's wireless card is the ONLY wireless card that has access to my router and I check it regularly!
