Edimax EW-7811Un, Mac OS X, Snow Leopard, 10.6.8.
According to the manual, you can use 802.1X tunneled authentication with Windows (it is mentioned e.g. on page 23, EW-7811Un User Manual).
However, the Wireless Network Utility under OS X (10.6.8) seems to have no option for 802.1X network authentication.
Since it's supported on Windows, the card obviously has the capability, so how is it possible to use it under OS X?
PS: I'm happy to edit any configuration file by hand and skip the graphical utility entirely, if necessary.
