I have a 2Wire router and AT&T dsl. The wifi works great for a tower up stares from the router and my brothers HP laptop. When I turn on my Macbook Pro (late 2008) there is a problem. Some times it will work like a charm for hours, but other times it will actually kill the Internet signal. After few minutes of browsing on my Macbook Pro, the router light turns red, and I lose any connection - and not just on my laptop, but all the other computers as well, including the one that uses ethernet. I try rebooting the Internet connection from either computer, but nothing works. I have to turn my Macbook off or put it to sleep. I know the Macbook and Macbook Pro line have had their share of wifi problems, but I don't remember hearing anything like this. Help please?
