How to set up a LAN with two routers?

Question

Computer networks

There is a cable from the provider, it is connected to the router (p1). A computer is connected to the router (p1) via a twisted pair cable. Also, a twisted pair cable goes from the router (p1) to another room where there is another router (p2), and two computers and a NAS are connected to it. There is no Internet on devices connected to p2, although devices connected to p1 have it. On p2, the twisted pair is plugged into the LAN port. What needs to be done / bought so that the Internet is on devices connected to p2 and these devices are visible from devices connected to p1?
Thanks in advance!
p1 - ​​ASUS RT-N66U
p2 - D-LINK Di-824vup+

Answer 1

Switch router 2 to access point mode - everything will be decided right away, why block routing where it is not needed.

Answer 2

First of all, check whether DHCP is up on p2, if so, turn it off, generally turn off all unnecessary services, leaving it at the mercy of p1.

Answer 3

And also check if the routers have the same ip.

Answer 4

p1. use as the main connection, p2. as an "extender/multiplier".

Answer 5

In general, normally, I see the following scheme: INTERNET <--->Router# P1
<---->Switch<---->LAN see what network it distributes (there is probably something like 192.168.0.0/24), Ruter#P2 reset all settings, disable DHCP and WAN port if possible, transferring it to an access point, so to speak. Clients will receive addresses from P1 and communicate with everyone.
