If I remember correctly, an ISP can push a new firmware to a Docsis3 modem at any time too and force reboot it.
Bothers me none of my modems have ever had the option to turn off WAN-side flashing, never know who is going to figure out how to take advantage of that.
- aspenmayer 5y agoHave a SPI flasher permanently connected, and a device on the LAN connected to that flasher, and to the LAN in order to automatically detect firmware version changes. When one is detected, dump the firmware update, and reflash your preferred version, and have it match the reported version of the new update. If you have a router in front of your modem, you could even make a killswitch that blocks WAN until the reflash is complete.
- pnutjam 5y agoIs that Pi based? I see some projects to turn a Pi into an SPI reader.
- aspenmayer 5y agoI was just theorycrafting. I’m sure it’s possible with off the shelf equipment. A rPi would be a decent choice for this.
