I currently have the retina MacBook Pro running OS X lion and want to force the wireless card to only connect only to 5GHz networks.
Both the 2.4GHz and 5GHz have the same SSID so I can not pick which band the wireless card connects to.
Notes: I live in a college dorm, so renaming networks is not an option. They do not have 2 different names in the preferred networks list. The network also needs a 802.1X profile to connect to the network. (I can modify it if needed) The security is TTLS with PAP.
