so i have a macbook with leopard i believe and my wireless internet will be good when i open up my mac but it will die out after a few minutes and sometimes even seconds! i believe its a problem with my mac because i would use my moms macbook in my room and it gets internet fine. i never move my mac around and i frequently have to turn off and on my airport to get a better connection. my wireless router is a linksys wrt54g.

also, not sure if it's a major problem, but i kinda ruined my battery by keeping it plugged in non-stop and never really turning off my mac. this i know is irreversible, but i dunno if it could be part of the problem.

so basically, something wrong with my macbook that will cause my wireless internet to die out.

thanks for any help!
