Hello and good evening self hosters! so i recently new to self hosting, i just installed my CM3588 DIY NAS with a bunch of services which is very addicting!

but i digress, so i recently found out today that we pay $11 a month to rent our router for our house. Which i personally think is ridiculous! So i am looking into buying to own, not renting to burn money. However the router seems to get internet from the ISP through moCA which looking at router that support moCA are rather limiting in speeds and very expensive. So my query for this fine, fine community is if i were to buy a coax/moCA adapter that then coverts it to Ethernet and then plug it into my router and and then by proxy my access points. would it work, wifi 6E looks super nice and there are very few options that are very pricey for modem/router combos that support moCA.

I am open to alternatives and ideas, and please correct me if i made any mistakes on terminally or my diagram

thanks folks!

Edit— my current router is a ARRIS Surfboard TG3452 DOCSIS 3.1 Cable Voice Gateway Modem Router with 802.11ac Wi-Fi & MoCA 2.0

So
