You can have your TMHI connect over Ethernet to a switch where you’ll have ports then there you can get your wired connections and your point to points and your mesh network all off that switch. If you need more ports add another switch.
I’d much rather go this route too, using “mesh” for WiFi just sounds like too much chaos for me. It’s not sexy, but it’s a lot easier to maintain and upgrade (the individual parts).
Honestly I’m at the point where I just rent the discs and rip them losslessly (BDMV for movies, MKV for TV shows).
