I am having the same problem. WOW technician was at my home today, but he couldn't get my CM400 to work since it had been used with Spectrum service (locked on IPv6). Can Netgear help with this? How do we unlock the modem to work with WOW? This is a modem I had purchased from Amazon, and I'm very unhappy that Spectrum locked it.
