I have a linksys wrt54g2 router and a aluminum macbook 2.4ghz running snow leopard. every so often, like when i am torrenting or sharing media to my ps3, my internet will suddenly go dead. The wifi bars are still there, but i have to turn my airport off and on again to get interent again. This is spiratic, but i have no idea what the issue is, any help? Suggestions? BTW i of course have tried restarting my computer.
