I just bought the new macbook. I have a linksys wrt160n router. I had the Macbook from 2 years ago (core duo 2.0 ghz, 2 gigs ram, airport G) running on the network. It is MILES faster than this new computer. I really can't stand that fact. The speed tests are MUCH less, youtube is always buffering, downloads are slow, I dont get it. Why would it not perform nearly as good as an older computer? The new one has N too, which should match up with the N in the router, so I'm lost for an explanation. Please help me!
