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).
