I'm really glad this thread came up... I have a 2.4 SR 15" MBP and I have ALOT of WiFi problems... I have a Belkin N1 router with 3 antennas and it's basically located on my brother's room, which is like 15 meters away or so from where my MBP is standing... I used to get full signal but when I go to my bed with it which is only a difference of about 2 meters it harshly degrades the signal, going from full to 1 bar and constant disconnects... Now for some reason in my desk where it used to get full bars it's always getting 3 or 2 bars... I don't understand the reason why... I have Vista installed because I'm going to play Age Of Conan, and right now I'm downloading some patches... and signal strength in Vista is 2 bars , 3 tops... while downloading the patches it's downloading at a 200kb/s rate.. I put my hand on top of the MBP and it goes down to like 10kb/s or turn on the bluetooth mouse and same thing happens, any person comes to my door and the signal declines to nothing... what the hell is this?!? I paid 2200euros for this?!?
Edit: I forgot to add, my GF's white MB works flawlessly ANYWHERE on the house though...
