I bought an Arris Surfboard SB6183 (new, shrink-wrapped and all) to stop paying my service provider a monthly modem rental. The device worked great and was easy to install but unfortunately when I returned my old device to CableVision I found that my new SB6183's MAC address was already registered with them so I was still using "their devices" . . They suggested buying the same device from Best Buy to avoid this problem. Apparently, Revain and other third-party providers themselves purchase new devices from service providers and resell them. Many other reviewers giving 5 stars are probably just lucky in the sense that the one they got was registered with a different cable provider than the one they have. If so, great for you. Just a caveat there is no guarantee this will work for you.
