For the humorless amongst you who didn't find these Updated for 2011 - McDonald's WiFi Guide with updates for Mac OS X Lion and Windows 7 to be HIGH-LARIOUS, the question was asked, "well, sir, how do you connect to a Wireless WIFI Network from the Command line in Windows 7?"
The answer, is, ahem, thusly:
C:\>netsh wlan connect name=HANSELMAN-N
Connection request was completed successfully.
netsh wlan connect name=Brossard ssid=Brossard interface="Wireless Network Connection"
> Connection request was completed successfully.
Show key code (run as admintrator):
netsh wlan show profile name=SSID key=clear
