Guess I'll tear down wlan2 > again. Do wlan0 and wlan2 have different MAC addresses? They need to. You could try adding the "bssid" flag to create_args_wlan2; that's supposed to make a unique MAC for you based on the hardware's real MAC. However last time I tried it (it's been a while) with my hardware it didn't work. So alternatively, you can add "wlanaddr aa:bb:cc:dd:ee:ff" to create_args_wlan2 (substituting a better MAC, of course). > The second part of my question is related to buying recommendations > for 5GHz USB wlan fobs that work solid as an AP (and virtual AP) under > FreeBSD.
