[Solved] How to Extend WiFi Range: Connect Two Routers for Enhanced Network Coverage

The situation is that I have a router in one room that emits a WiFi network with some name. I have standard settings, i.e. gate 192.168.1.1, IP assigned automatically by DHCP from a manually set pool (range of several IPs, more devices are not connected here at one time), WiFi broadcast done, WiFi password, WAN connected to the modem from the service provider, all automatically , dynamically. The router obtains some of its public IPs, and so does DNS. The devices connect to the router automatically via WiFi and one via Ethernet. I'm in an apartment block.

Now: how to set up a second router in the second room so that THIS router will use THIS network and advertise it under a new name for devices that are not catching up on WiFi in that room well from that first router? It's about spreading the range as if from the base router a desktop computer sometimes has a problem with catching 3 lines out of 6. The internet then works poorly. Then I would put the second router next to the door so that this computer was closer. Will someone write me the settings? I know the basics from the network and I am unable to configure it.

I set up the second router to have WAN Static and 192.168.1.1 in here. of this base router. In theory, it should be ok, but I don't know what's wrong. I guess something with masks is wrong.

Or a second LAN router to the first one. Or a two-in-one router, that is, with two radios. Or ap with a router over the cable, then ap receives wifi from the first lan, it is the second router and it broadcasts new wifi.

Wait ... I don't quite understand. So it won't work without a cable from one router to another? The problem for me would be solved by moving this base router to a different place, but I do not have such a possibility.

I do not understand this sentence:

How can a router receive WiFi over a cable? [/ Quote]

When you set up the AP with the router in the second room, the AP receives wifi from the current router, the LAN AP is connected to the second router and it broadcasts the second wifi. The point is you must have two radios. One for connecting to the current router and communication and the other for broadcasting a new other wifi.

This is how it is to be done:

If you want everything wirelessly, you need to buy a repeater, but personally I strongly advise against it, because they are problematic devices.

Approx. I understand then. It will not do without a cable or a router with a second radio, which will then be used to connect to this base router. Maybe someone will recommend such a router in a reasonable "home" budget and know that it will work? My main router is TP-LINK. I don't remember the model at the moment.

What internet connection do you have (especially your bandwidth). What budget do you have? A "butt joint" device or something more future-proof? An apartment or a detached building?

The repeater remains, and that's it. I close the topic.
