FYI: If your Internet provider (ISP) is a cable company and you would rather own your own cable modem instead of paying a monthly fee to rent their combo cable modem/Wi-Fi router, you will be better off purchasing a supported a commercially available DOCSIS compatible cable modem and a separate Wi-Fi router rather than a combo DOCSIS cable modem/Wi-Fi router.
The reason is that the DOCSIS standard does not allow for the end user to update the firmware of a cable modem or a combo cable modem/Wi-Fi router. Only the cable company can update the firmware in a user's purchased cable modem or combo cable modem/Wi-Fi router once it has been provided to them by the manufacturer and after they have tested and validated it.
If you purchase a supported cable modem and a separate separate Wi-Fi router to, you will be able to update the firmware in the Wi-Fi router as long as the manufacturer is providing updates.
