My Intel wireless card is significantly slower in Ubuntu than it is in Windows 7.
According to iperf (with the laptop a couple of feet from the router and the server plugged into it):

I have attached the output of Wireless Script, which should give all the necessary details about my setup. Any thoughts would be appreciated.
