I've started to notice that my wifi speeds have decreased by more than 75% at my apartment at school and at my house... I get random bursts of actual speeds but I can never actually get a consistent good speed unless it's my upload. I'm really starting to get convinced that it's my Macbook Pro and I took it to a genius bar, but all they did was run a speed test using speedtest.net and got a 40mbps connection. I'm not sure how fast their network is as a whole, so 40mbps/xxxx mbps? But either way, 40 is really good.? The genius also tried running the Apple Hardware Test but couldn't get it to work, so he sent me on my way saying he sees no issue... Oh, and my wifi on campus just sucks. It disconnects 90% of the time. I've reset both of my routers and reconfigured them multiple times including changing their operating channels with no luck. I've tried doing a PRAM reset and SMC reset with no luck. I've also reformatted my Macbook Pro and installed a fresh copy of Lion to no luck. I can't seem to get AHT working on this either, so I'm thinking of just taking it to the Apple Store again and trying my luck. This is starting to get really annoying, so I'd appreciate any comments/suggestions on this. Thanks guys!
