Two houses, two ISPs, one network

[ceswiedler]

Hi - I saw the answer to this question here https://zentalk.asus.com/t5/networking/two-asus-routers-with-two-isp-providers-one-connected-to-each...

...but it doesn't seem to answer the part about multiple internet connections.

My parents live next door and I'd like to set up a single wireless network for both houses. Both of us have existing ISP connections that we'd like to keep (and use) so that we have redundancy.

I know I can get a single network via AiMesh, and I've read up on having multiple WAN connections on a single router. But in this case the WANs will terminate at separate houses and I don't want to run ethernet cable between them. I'd like for traffic to be routed through the 'best' WAN connection.

Is this posible?

There is a bridge mode, but it is one way.  Similar with Dual WAN, you’d setup a single main router.  All directions point to one main router and node(s).  I could imagine possibly running Ethernet (2) from each router’s LAN port to the each other’s 2nd WAN port, then trying to enable Dual WAN Failover mode and enable Fallback.  Then name SSIDs in both houses to the exact same name.  You’d have separate AiMesh in each but this is the closest I can think of to a solution…

Found this thread for you.  It’s more complex than what you are looking for but has the solution in there.  I did not read through all of it but stopped somewhere in the middle.  It was at the concern of VLAN tags being shot out the WAN.  I have heard an unmanaged switch will strip the VLAN tags off packets so I was curious if sticking one in between the ONT/Modem and router would solve that concern…
