IIRC there is a code that is generic for them. I don't remember what the code actually is, but I remember doing it for someone.
Word of advice though for those that use this app or a MAG box, there is a scam running where people are having their lines shared. Known URLs are being scanned, and the macs are being sniffed, then being used elsewhere. Im hearing a lot of providers are just going to be stopping MAC association completely.
