In regards to a friend's house-- They have a wireless router setup ( a linksys ) with 3 seperate windows laptops connected wirelessly and a desktop connected directly to the router. Whenever I connect to their network with the correct WEP key, the internet will work for about 5-10 minutes. Then all of the machines on the network will cease to get out to the internet. The signal won't drop or anything of that nature, everything will say connected, but browsers including mine will lag at the "connecting" mark. This in turn causes them to have to reset the router. This only happens when I connect my macbook to the network. Any ideas? Thanks in advance.
