What is the best way to scale the network?

Question

Computer networks

Two buildings, TP-Link 741 is installed in one. The second building is 60 meters away, and a router needs to be installed there. Will I do it right if on the side of the TP link I connect to the LAN port, and on the side of another router I connect to the WAN port and set the dynamic settings? In the wireless network settings, set the SSID and password to be identical to TP-Link 741?

Answer 1

1 Option
LAN port 1 - WAN port 2. For 2 WAN settings, receive IP via DHCP. On LAN 2 you do addressing different from LAN 1. You write routes on both routers in the LAN network.
2 Option
LAN port 1 - LAN port 2. On 2 The WAN settings do not matter in this case. Disable DHCP. And you will have one L2 segment.

Answer 2

As already mentioned above: depending on what you already have and what you want to get.
If you just need to combine 2 segments into one common network, then we transfer the second router to the hub / switch mode and disable or delimit the DHCP server (in principle, it is better to delimit - it will work faster and more reliably). D nfrjv ckexft wan becomes a regular lan port and the connection goes lan1.1-wan2
If you combine so that some services are shared (file dump, 1C), but the networks are isolated and each of them has its own Internet, then lan1.1-lan2.1 and filtering traffic on these ports is configured.
If there is complete isolation of networks, with receiving the Internet from the head building, then connect lan1.1-wan2 and configure the second one to receive the Internet and other things through a static route.
PS: In any case, the IP addresses of both routers must be static, otherwise you won’t get glitches and you won’t know which router is hanging on your network, DHCP is needed only for incoming devices
