TCP window scaling has been enabled by default in all Windows systems since Windows 2000. So that seems unlikely. The TCP window-size theory also doesn't explain the difference in speed between downloading from the netbook and downloading from the NAS. I don't think the laptop HDD write speed theory explains the faster netbook download speeds either.
WiFi errors/retransmission is possible, esp. if the NAS is faster than the old netbook. Lowering the link speed to 150 (or even 72) is worth a try.
anynamewilldo85- when you right-click on the wifi link in the system tray and select status, what link speed are you seeing?
I agree that asking for a better router is worth a try - gigE would of course be nice, and it is quite possible that the root cause of this problem is something not right in the router - insufficient buffering on the LAN->WiFi bridging for instance.
