Hi, where I live we have cable internet, it seems this is not supported by existing OpenWRT firmware. But as far as I understood, the router is the same and just has a different modem. This could need proprietary firmware, maybe blobs etc. everything not nice, but isnt the router Software kinda independend of the modem? I dont have experience with this, but would like to try to make a model with cable work with a DSL / fiber OpenWRT software by adding the missing modem firmware. Is there something I missed, is this in general how OpenWRT is made to work with different modems? Also: can I have 2 routers on the same cable, to try it before switching to it permanently, if I have a cable box with 3 ports and one free? I dont know much about this, as the payment plan seems to be for the whole house connection no matter how many routers inside.
