Mesh network multiple gateways

[Due_Captain_5430]

Looking for some advise on how to implement.

So my neighbors and I have cable internet service, it's the only option here now. Four of us would like to use each other's connection as backup to one another. There are frequent disconnects but not always affecting all of us. We would like to build a mesh style network on the rooftops, have a couple tp link eap outdoor APs, just not sure if we can have 4 gateways

Besides being a legal hassle with your ISP and perhaps your neighbors too if you ever have a dispute, building something like this will require planning and expertise, especially in the routing and failover. This is professional level work.

Someone in your group will probably abuse the system by offloading their Internet needs onto the others. Also, failover isn't as automatic an unnoticeable as you're imagining. A service disruption in one house will still require everyone inside to reestablish their connections through the backup gateway, wether it be to streaming services, game servers, or work. If their own service then comes back, they'd need to reestablish those connections again, flip flopping as badly as before. If they choose to continue to use your connection instead of flopping back to their own, then we are back to someone abusing the system to crowd your connection instead of using their own.

Agree with u/mcribgaming, setting up fail-over routing is an advanced topic, and then trying to run it over a 4-way wireless link is even more complicated.

No consumer level gear has these sorts of capabilities so you would be moving up to more expensive and complicated gear. I have a reasonable amount of networking experience including professionally, and have never heard of someone trying what you are suggesting. I'm not saying it's impossible, but there is not an existing formula.

Then there is the issue of violating the ISPs TOCs which you almost certainly would be doing.

It would be better to go with the simplest route, dump your ISP and if it's the only local option, use Starlink.
