You're using an old driver. Now I've found this:
Too bad nothing like this is in the System Admin Guide...
... and this is out of date.
Nonetheless, following these directions and using the /usr/share/kde4/services/plasma-applet-networkmanager, 5.2GHz APs are --not seen--. I do see my 2.4GHz AP and can associate/communicate. There does not seem to be a concrete way to determine it's running on 'n', only indirectly through speed tests.
Better not change your config or do any software updates if it's working on 5.2GHz. Do a brief search on the listservs to see why.
