Two days ago I got a 'new' refurbished 13" MBP from Apple to replace my aging 2006 MB. It's ok, but not quite as nice as I expected. One major thing I've noticed is that the wireless reception is much worse than my old MacBook. They're both connected to a Netgear WGR614 v9, but the MB is getting about 2/4 bars, while the MBP is constantly dropping the connection. In fact, right now I have the MB booted in Win7 and it's running Connectify, in order to share the connection with the MBP. I'm downloading the latest software updates right now, and then I'll see if any firmware is available, but I doubt that will make much of a difference. Is this because the new MBP is made from aluminium?
