Notes:
1. EveryNTX_APcallwillcausetheWM18xtodisconnectfromthecurrentSSIDifitisconnected
andtrytoconnectusingthenewSSIDnameandpassword.
2. ThepreviousSSIDandpasswordwillberetained.IftheWM18xconnectstothenewSSID,the
oldSSIDandpasswordwillbecomethebackup.IftheWM18Xdoesnotconnecttothenew
SSID,thenewSSIDandpasswordwillbestoredasthebackupSSIDand password.
3. MakingacalltoNTX_APwilltriggeratleastoneNTX_ONLINEmessage
