I've been having a lot of trouble trying to connect to a WPA secured network on my new MBP. I always get the error saying "connection timed out". I've read many other posts and blogs about people having the same problem but I haven't been able to find a fix that actually works. It works only when I reboot the modem/router but once I restart the computer or put it to sleep the problem reoccurs. I tried booting into my windows partition and have the same issue. Does anyone know what could be causing this? My brother has a 3 year old MBP and has no problem whatsoever. Thanks
