I am having issues with my internet connection. For some unknown reason, my connection will drop frequently. I am using a Linksys WRT54G router. Connected to it are 3 desktops (via cables), a Xbox 360 (wireless), a laptop (wireless), and a PS3 (wireless). I have been noticing that it seems to drop the most when I am on my Xbox 360 trying to play games online. When I first sign in to Xbox Live after turning on my Xbox, it will usually drop me right away and I have to sign back in. I've been playing Call of Duty Black Ops and I have been noticing that when I try to join a game, it will join but then kick me out because a loss of connection. I can then re-join the game and it usually won't have any problems. My brother claims similar problems with his games on his desktop. I have tried restarting both the router and modem but I am still having the same issues.
I don't know what other information you need so I can answer any other question you may have. Thanks in advance for all of the help.
