Thanks for sharing this information. It may be useful for other users with enterprise security.
The option Allow Fast Roaming (CCKM) is not enabled by default.
It actually was enabled in the driver bundle I downloaded from Dell for the Latitude E7240. For other models I've noticed that those options are deselected by default, so might have been a slip-up for that particular download only.
Hmmm..... Intel's ProSet software bundle has "Cisco Options"???
I don't currently have proset installed, so can't check that.
It does - but they only appear as configurable options under each wireless profile if you are connected to a Cisco network (or WPA2-Enterprise - not sure what triggers it).
