I know that the subject mentions USB, but I was responding to Stefan's statement regarding "USB or otherwise." He's basically correct, of course, that there are *virtually* no modern WiFi cards of any sort that are supported by totally free drivers / firmware, but there are apparently at least a few that do support 11ac (I'm not sure if there are any at all that support 11ax). -- Celejar
