I just demo'd my older black plastic Macbook right next to my new aluminum Macbook (2.4). My black one was getting full reception while the new Macbook was getting no reception at all. I have read that the aluminum housing in other models could interfere with reception, but this is kind of silly. In other parts of my house I go from full strength to barely a signal within 8 feet. Add that to the weird screen refresh problem I am having (see link to youtube that I found that affected a macbook pro) and I am less than impressed with the new machine thus far. http://www.youtube.com/watch?v=ngurt41PyZo Any thoughts on how to improve reception? I am using a Netgear Rangemax G router but was thinking about switching to an Apple Extreme for the router and an Express to link to my stereo. Perhaps that could improve my reception? Any thoughts or anyone else experiencing the same troubles with this new machine?
