Configuring Two TP-Link Routers in One LAN: LAN Addresses, DHCP Settings, and Limited Wi-Fi

Hello all.

I have a problem with the configuration of two routers in one LAN. My provider Inea provides internet via modem. A TP link router is connected to this modem, from this router the LAN cable goes out from the LAN ports to the second router (already to the LAN port, not the WAN port - I read that it should be like this).
On the first router I have:
LAN address: 192.168.1.1
DHCP enabled
IP start: 192.168.1.100
Ip end: 192.168.1.199

I read that when I connect a second router (also TP link), with a cable from the first router to the LAN port, I have to switch off on the second DHCP and set some IP from the scope of the first router.

Which IP are you referring to? IP LAN? e.g. should I set it to 192.168.1.102? and should it work?
I did as I wrote above and it doesn't work, it connects to the second router but shows that with wifi, the connection is limited.

Thank you in advance for your help, because I have been tired of it for 2 days.

Configuring the second router as an AP -> https://tplink-forum.pl/index.php?/topic/668-router-bireless-jako-ap-punkt-dost%C4%99powy/

The second router's IP address should be configured from outside the main router's DHCP address pool, i.e. 192.168.1.50

The main router let's call it "1" has:
LAN address: 192.168.1.1
DHCP enabled
IP start: 192.168.1.100
Ip end: 192.168.1.199

What should I enter Lan ip? By default I have 192.168.1.1 (but this is the main router).
On the other, should I change wan type connection from Dynamic ip to static ip?
That's what I did and entered 192.168.1.50 and mask 255.255.255.0 and appears when I try to save the settings that ip lan and ip wan cannot have the same subnet mask.

The router 1 is attached

"Connect with a lan cable to the other two"

I only have two routers, the main one and one more. I left the main one unchanged, and on the other I changed the IP lan to 192.168.1.2 and it still doesn't work. Of course, dhcp is off, and the WAN tab displays: Obtaining network parameters.

Oh, and just to be sure, when it comes to the other router I connect it to one of the LAN ports, not WAN? because that's what I do, to LAN!

1. You connect them with the LAN cable of the first -> LAN of the second
2. You set the same SSID on both
3. You set identical encryption on both
4. You set different channels (different by 3 to 5, not adjacent)
It must work, but you will see it as one SSID.

This doesn't interest you - you connect to a LAN port as above.

In my link you have everything described, configuration as AP (WAN port empty) and if you have a working cable it must work.

Thank you very much for all your help - it WORKS ))

I could write to you right away, and so after the torment, worn fingertips from cables and with your great help - I succeeded.

Thanks again, have a nice day!
