My MBP gets 10Mbps download (ISP max) while my Vista (64bit) computer only gets between 4-5Mbps download.
Both MBP and Vista desktop computers are connected to an Apple Time Capsule router. The TC plugs directly into my cable modem. Both computers connect wirelessly to the TC. Both are using 802.11n. The TC is under a desk, beneath both computers.
I initially used this link http://www.makeuseof.com/tag/top-5-vista-tweaks-to-increase-internet-speed/
to resolve the Vista speed issue. It went up to 10Mbps but that was only temporary. Even after a reboot, speed doesn't improve. What is it about the Vista box that it only gets 1/2 the speed of the MBP?
