I got a brand-new 2.5ghz 15" MBP with a 320gb 7200rpm hard drive and 4gb of RAM exactly a month ago. I'm using it to hook up to a wireless network with cable internet. For some reason, I can only get a maximum download speed of 40KB/s with this incredible machine! I don't think it's the laptop itself, because at my friend(the mac user who converted me)'s house, it got a download speed of 750KB/s. Both speed tests were done at www.speedtest.net . There must be some way to improve my dowload speeds on this laptop...it takes ten hours to download 1gb! Can anyone help me?
