How to properly configure the router?

Question

Computer networks

at work in office 1 there is a router 1, the lan port of which is connected to a cable that is stretched to office 2. In office 2, wifi is not caught from router 1. I want to turn on another router in office 2 (router 2), exclusively for distributing wifi to mobile devices. In which port of router 2 you need to plug the cable in order for everything to work. How to make settings? Router 2 - Netis wf2411e
Thanks in advance

Answer 1

plug into the LAN port.
all LAN ports, as well as the wifi network interface in router2, are bridged. More functions are not needed from it.
on router2, disable the DHCP server so that it does not conflict with the distribution of ip-addresses by router1

Answer 2

The easiest way is to plug the cable from "router 1" into the Netis WAN port and configure it as a router, with "Internet Connection Type" - DHCP.
Ideologically more correct - if you configure Netis as an access point, not a router, so that addresses are issued by one router (1)
