I had the same problem, I bought a 150$ UPS for the socket my modem is on and the problem has stopped. It might be a power supply issue. The box said voltage regulation on it.
Good afternoon, ooshawn. From what I can tell, we should still be able to properly activate that device for you. Not sure what was going on to cause any complications on our end initially, but I'd like to take a look at your account and see what I can do to help.
Please send me a PM with your first and last name, plus the MAC ID from the Asus device and I will help you out from there. I look forward to hearing from you!
