How to connect another WIFI router to a WIFI router?

Question

WiFi

Hello! It is necessary to bring the Internet to the gym. At 100 meters there is a wifi router (A), they threw a cable there and plugged into the LAN port, on the source router (A) DHCP is enabled. In the receiver router (B), the cable is plugged into the WAN port, in the WAN settings - receive dynamic IP is active.

We connect on the phone to the WIFI of the second router (in the gym) - connected without access to the Internet ... go to telegram, any program - writes "waiting for the network". We rechecked all the settings, rebooted both routers a couple of times - everything is the same ...

On the second router (B), we reset the settings to the factory settings ... we are connecting ... it no longer writes "without access to the Internet" ... You go into telegrams - it works, I write text messages - they reach. I send a photo in the cart - it tries to send, but it's clear that it doesn't even start and again the status in the cart is "connection"

Where to dig?

PS in the normal way to put the switch, and already from the switch ports to both routers - there is no way yet.

UP

everything, the balalaika started up ... cut down on B dhtsp and registered 192,168,0,2 in the LAN (on router A, by default, it also costs 192,168,0,1 .... that's the conflict) put the incoming cable into the LAN.

Thanks to all

Question one - what is the LAN address of router B? It should not be from the subnet of router A
For a good thing, you need to do it like this
Give the IP address to router B from the LAN subnet of router A
For example - B 192.168.0.2
A - 192.168.0.1
Disable DHCP on router B
plug the cable into router B into the LAN port
Then it will act as an access point, clients will take all settings from router A, router B will be used as a "switch" + wifi point
