IPTV66 Help here!
i have 2 routes but am unable to change the mac address for one of my boxes. it shows the same mac address for both routes. if i try changinging mac address it says that it already exists and stays the same. not sure what to do.
 
i tried that as well but its just stuck on the same mac all the time. i guess we just have to wait and see. i also did not receive my confirmation for renewing my subscription to my email although it does show the time was added to my account. very confused.
