Connecting a router to another router

Question

Computer networks

Greetings! I have a problem and I don't know how to solve it. I ask for help from those who understand.

I have a router (ZyXel Keenetic) to which Yota is connected. This router is connected to the network (via a switch), where there is a laptop, printer, hdd storage.
In another part of the house, I have another router (TP-LINK WR741N), to which there is a wire from the network of the first one. My computer is connected to the second router via wi-fi.

How to connect the second router to the network of the first one? What would it be possible to use the Internet, and a printer?

Perhaps my second router is not suitable for this? Then what do I need to buy in order to set up a wi-fi network at the other end of the house?
Thanks in advance.

Answer 1

There are two options:
1. As mayorovp mentioned above, put the router in bridge mode. However, not all firmwares allow this.
2. There is another way. Its essence is that for any router, the LAN ports and the Wi-Fi interface are combined into one segment. Those. you can think of 4 LAN ports as a 4-port router (wi-fi is its fifth port). To avoid problems, you need to turn off the DHCP server on the second router and connect the cable from the first to one of the LAN ports.

Answer 2

Disable the DHCP server on the second router and connect the wire from the first router to the LAN port of the second one. WiFi configure at your discretion, preferably the same name and the same frequency.

Answer 3

Connect the WAN of router 2 (the one without the Internet) to the LAN port of router 1. The network of router 1 must be different from router 2. That is, if router 1 is on the network 192.168.0.0, then router 2 must have a different network from the first router, for example 192.168.1.0. In this case, disabling dhcp is not required anywhere. Since router 2 is a simple computer for router one.

Answer 4

In this case, the easiest way is to put the second router into bridge mode.
