Hello @jonykremer
That really isn't going to work well at all, I'm afraid. Yes, they will form multi-hop topologies, but only under conditions where a node can't get through directly at all. Since WiFi will slow way down in order to get through, it's more likely distant nodes will be talking very slowly (and perhaps unreliably) in one hop rather than going through intermediate nodes. Keep in mind, even if they did go through intermediate nodes, the data would be getting retransmitted back out on the same channel again, which would just cut the channel capacity in half anyway.
This is why the optimal performance and coverage recommends placing the primary unit as close to the center of the home as possible with secondaries no more than one or two rooms away from there. They will provide coverage to more distant client devices.
Now, in your case, since your internet service is coming in at one end of the home, you are going to need to do some work to get a placement close to this. Specifically, an Ethernet cable run from where the internet service comes in to the middle room in the house so that the primary can be placed there instead of at one end.
But, while you're running cables, you might also consider running a few more and just using Ethernet to connect all of the secondaries back to the primary (use one or more inexpensive, unmanaged Ethernet switches to make more Ethernet ports available through the LAN Ethernet port on the primary). This can work really well, providing both good coverage and high performance. You may find you only need three total units rather than five.
