The reason leased modems fall onto the EOL list sooner is because it takes time for Comcast to rollover those units. Comcast has to continue to support those units until they've removed them from the field. Once they've rollover all the units, then the modem is put on the customer owned EOL list.
The EOL list serves two functions. They will remotely update the firmware of supported modems using the TFTP interface and the will validate supported modems on their network for the speeds offered by the modem. When your modem falls onto the EOL list it is no longer updated and they cannot guarantee your speed. The former is a security concern for them, and the later is more of a nuisance if you upgrade your service to a tier your modem can't achieve on their network.
- matheusmoreira 8y agoSo ISPs remotely push updates to their customer premises hardware? This doesn't apply to the customer's own equipment, right?
- cptskippy 8y agoIt does, if you access your cable modem's web interface you'll find rebooting is the only function you can perform otherwise it is read only. ISPs manage Cable Modems regardless of who owns them. It's part of the subscriber agreement. If you have an all-in-one device that is a cable modem, router, switch, and wifi ap all-in-one; the cable modem is still managed by the ISP.
- matheusmoreira 8y agoOnly the modem is managed? Is it a separate system/firmware? That would make a lot of sense. My ISP gave me a VDSL router and I can configure a lot of things via the web interface, but to get access to features such as bridge mode I'd have to replace its firmware. Is there a way to get the modem as a discrete component, rather than integrated into these all-in-one things?
