Yeah, swapping the adapters wasn’t really the point. It’s the router (working eero) that is important.
In my cable Internet (Comcast) setup, there’s a similar issue. If changing routers, you need to power cycle the modem, sometimes even leaving it off for a few minutes to trigger the system to issue a new DHCP WAN IP to the new router.
So in an attempt to workaround not knowing how to trigger that in your ONT (unless you’re ready to leave the ONT and routers powered-off for “at least one hour”), just move the eero currently perceived as the router to where you want the router. (It *would* be useful to figure out how to swap routers, at some point.)
Oh. Leaving it all powered-off overnight likely would have worked, as well, without the need for moving devices. (overnight > 1 hour
)
Possibly. Given this, you’ll definitely want to review how the coax lines are connected, starting with getting each line identified and labeled. Pretty easy to do with terminated cabling and a pair of working MoCA adapters. (

I hadn’t considered this as likely as the router authorization issue because you’d said that the FCA252[25GW] adapter downstairs indicated a successful MoCA link, with only the two “WAN” adapters powered-on.
