How to connect several routers in series in a network?

Question

Computer networks

Hello,
in order to have wi-fi everywhere in the country house and on the site, I decided to place several routers around the territory, they are connected by a twisted pair cable.
Router 1 (dlink 300s)
- Internet is connected to WAN by wire - Router 2 and Router 3 are
connected to LAN
- distributes wi-fi
Router 2 (dlink 300a)
- is connected to router 1
- distributes wi-fi
Router 3 (netis WF2419E)
- connected to router 1 and to router 4
- distributes wi-fi
Router 4 (tenda N3)
- connected to router 3
- distributes wi-fi
On all routers, except for 1, I disabled DHCP, NAT and Firewall, for WAN I registered the Dynamic IP connection method, I used the LAN port to connect to the "upstream" ones in the chain. As a result, there was no Internet on routers 3 and 4 both by wire and wi-fi, the connected computers did not receive IP, on 1 and 2 there is Internet for any connection. I know it shouldn't be like this, but here it is.
I want to try to make sure that each router is on its own subnet and with a working DHCP. Such questions:
- how to prescribe routing rules?
- Do I need to set the same wi-fi settings on all routers (ssid, authentication type and password)?
EDIT
I repeat that all but the first router are connected to LAN-LAN, all but the first router have DHCP, NAT and Firewall disabled. I checked the wires, crimped them in a straight line EIA / TIA-568A

Answer 1

You are moving on the right path. All routers with NAT. Everyone must be known to be on different subnets for routing to work.
WAN ports of slave routers in the same network as the main router, LAN ranges of slaves in a known different network. Everywhere NAT. For the convenience of administration on subordinates, allow access to the admin panel through the external interface.
You can try to find the access point mode of the routers in the settings, then it will work as a switch with an antenna, the IP address will be issued by the main router, NAT will not be used, everything is on the same network with the base router.
Ideally, when you want to throw out this menagerie, look at Mikrotiks, they have CAPsMAN technology, which allows you to make a seamless Wi-Fi.
And there will be a lot of money, buy a tsiska :)

To be honest, you do not have routers, but access points.
Hence the important things.
This is a combined device. Usually, if you look at the ports, something like a port for the Internet (WAN) and 4 ports for a local area network (LAN) are marked there. LAN ports do not carry L3 logic. That is, you cannot natit these ports, assign ip addresses. But the WAN port can do it.
From here If you want to place everything on the same subnet, you need to connect access points through LAN ports.
In this case, the circuit will be similar as if you connected 4 switches. Roughly speaking, in this scheme, you have one device that has DHCP and Internet access, and the rest simply pick up all the settings.
If you want 4 segments. Then you need to make a WAN-LAN port connection. Downstream WAN ports receive DHCP from an upstream router.
Regarding Wi-FI, actually how to organize it does not matter. You can issue one SSID to all devices, you can use different ones. If you have one password and one SSID, the device may switch to a new point on its own.
If you look in the direction of designing wi-fi networks, then there is a recommendation not to produce extra ssids.
