Thanks in advance for anyone who can help me here. Ok I use a linksys wireless router which I share with my girlfriend. The first problem i'm encoutering is I think the people in the apartment below us are jumping on our network even though I have it secured with an impossible password. I don't know much about security but i'm sure they could get into it if they knew enough about router security. So my first question is how do I know if there's someone other than myself and my gf using the wireless? And also, how do I stop them if they are using it. Someone said something about only allowing the MAC address for my computer and hers but I don't know how to do that. My second problem is that I play a lot of counter strike and those of you who play know how important your ping is. Well my gf downloads and uploads a lof of music and pictures which always gets me booted from servers. I was wondering if theres a way I can limit her bandwidth to about half of what it is now so that this wont be a problem. Please try to make any response to either problem as non-complicated as possible. I know how to log into my router via the IP but thats about it. Any help would be awesome. Cheers!
