Hi everyone, I have a home internet network set up, where the cable modem is plugged into a desktop PC and then I use a router for wireless for my MacBook. When I set it up, I had major problems figuring out how to use a WEP password protected setup. I spent several hours, then gave up and just set it so that only MAC addresses that were on a permitted list were allowed on. I just set it so that only my MacBook's MAC address could get on. Is there a way to find out if anyone is stealing my Internet? Sometimes it seems a little slow, but that may just be because it's a high-traffic time and the whole neighborhood is using up the bandwidth. I want to find out if anyone is stealing mine. Also I was just generally wondering if using this MAC address blocking is sufficient security and how hard it would be for someone to break in. Also, if someone broke into my wireless, could they steal anything besides my internet? i.e. could they do anything more malicious?
