I tried to self-activate the modem with my ISP. It failed multiple times. I tried to activate the modem with their tech support as failed as well. The modem is on their approved list. Their support looked up the MAC address and no record associated with that MAC address. I also was able to confirm that the MAC address has no record and it is NOT associated with any known manufacturer.
I bought the modem from Amazon and it was sold directly by Amazon.
