.All devices should be getting the same subnet (255.255.255.0) from the main router

Is the default gateway address for ALL devices and ALL DHCP router settings 192.168.0.1?
Just from a 'thought experiment basis' I'm guessing your server (laptop) is on a fixed IP and you access it via that IP rather than a domain name or hosts entry. No matter where it is - that server is still 'serving exactly the same soup'. Little pile of stones/thus/therefore - if you cannot 'see it' on a given segment, you have a connectivity problem. The server can't control what the network delivers. Routers turn LANs into segments, and to some extent how that is done is a function of the router design (for example some routers cannot handle recursive NAT). I suspect we are dealing with a segmentation issue that is caused by a non-apparent setting in the routers (are they all the same?). [That is why I asked how it was cabled]
The using same SSID could be part of your issue, I'm not sure (the idea has my wifi brain in a catatonic state LOL). I have chained routers working perfectly OK, but there are lots of caveats.
OK here are two fix suggestions:
First try this -
1. Fix the ambiguous SSID issue with 3 'zone' names - Router-1, Router-2, Router -3 (or something more imaginative )
testy testy testy
leave that in place -
Now do this:
the cable from 3 to 2 - plug it into a LAN port on 3
the cable from 2 to 1 - plug it into a LAN port on 2
You now have a ONE segment LAN, switches are transparent and can be daisy-chained until the MAC tables have problems OR you have a spanning-tree issue.
AND writing this i know the problem -
it is a segmentation issue.
on 2 and 3 the wireless devices can't GET a DHCP lease - its turned off, and because they are on a segment - they can't see the only router handing out addresses.
Hope this is not too confusing... This may need one more iteration to get there -- I am thinking about it...
The routers don't have any WAN ports, only LAN ports.
