Hi,
is it possible to add 6591 support? I know this product is kind of niche, i got mine for 30 bucks after leaving my apartment and got a house. now i use this fritzbox as a Wifi AP / managed hub for my home Network. Would be great to use openwrt, even if this means i have to drop its internet ap / modem functionallity.
There are exactly zero DOCSIS devices supported by OpenWrt. Depending on the hardware inside the device, it might be possible to have partial support (processor, wifi, Ethernet), but the cable side would never be usable.
If you’re still curious if it could be done (minus the cable modem part), you can start the process with this guide:

Edit: it appears the device also has telephony (dect) support. That would not work under openwrt, either.

dropping DECT and Modem would be no problem for me, i dont use landline phone anymore, cable is no option in my new home either ( currently on Starlink, waiting for fiber...) i will take a look, thanks for the link!
Ok, get oem bootlog oem fw image, try to identify supported components, the specialist boot chain. Likely some sort of truusted boot will be end of it.
Serial adapter may help with all three. Share bits, we can help if you stuck

This pull request for Puma 6 support might be relevant: https://github.com/openwrt/openwrt/pull/16028 (Fritzbox 6591 uses the successor Puma 7).
