Ad-hoc stopped being defined in the specs in 11b as I recall. 11g makes no specific definition of ad-hoc specs - some manufacturers allowed it at 11g speeds, some at 11b speeds only. 11n drops adhoc entirely, as I recall. It also removes wep (at 11n speeds), and imposes other limitations. It's not surprising that a modern device just doesn't support ad-hoc - it was a half-assed spec from the beginning and they're desperately trying to kill it in favor of, as Bruce says, wifi-direct. -m --
