I keep getting disconnected from party. HELP!!

[PokeHer]

Hi. I just moved to cape cod for the summer and am living with my girlfriend in the finished basement of this woman's house. She has a wireless router setup on the 1st floor, and I have a wireless card in my PC. They are both the wireless-G by linksys, which is 35% faster than normal. But I keep getting disconnected from party.

My wireless connection is usually at "very good" and 125Mbps. I am still online when i get disconnected, so I am thinking that this might be a problem with the servers in this area... not many people live here year-round, and during the summer, populations go up by as much as 10 times. So, maybe the networks just cant handle all the traffic.

Basically, can someone tell me, with certainty, if the problem is with my computer and its wireless conenction or if the problem is with the network.

Thanks!!!
