How to set up: Internet from an adsl modem to a wi-fi router, from it to the next wi-fi router and to the receiver?

Question

Computer networks

Good day.
The situation is the following. There is Internet from Rostelecom via a telephone line. Accordingly, there is a Tp-Link adsl modem for it. I need to connect a wi-fi router (also Tp-Link) to the modem to distribute the Internet around the house. Then, in order for this Internet to receive another wi-fi router over the air (and this one is also Tp-Link) and from it, via cable, connect to the receiver, which works for cardsharing on the TV. Yes, it is very tricky, but there is no other option. It is necessary just like that, pulling the wires is not an option and buying an additional one too.
I kind of set everything up, everything worked, both the Internet and cardsharing, but after a day or two, at best, after a week, the Internet fell off on the second router.
If anyone has come across or has ideas for setting up - please describe or link in detail from the very beginning. But I would like to need some "ideal" settings so that nothing falls off, otherwise I've tried everything in different ways, but somehow it should work stably?

Answer 1

Here is an article on setting up the repeater mode.
Theoretically, it looks like this :)
If there is access to the modem interface:
1. IP modem of the form *.*.*.1/24 DHCP Enabled (if any).
2. 741ND IP type *.*.*.2/24 DHCP Disabled (if enabled on the modem). Set up a wireless network, select a channel (required).
3. 3220 IP type *.*.*.3/24 DHCP Disabled. The wireless network operates in WDS mode as described in the mentioned article .
If there is no access to the modem interface, configure a subnet different from it, set the IP routers *.*.*.1 and *.*.*.2, respectively.
Why could it all fall apart?
I’ll consider it with my own example, I have an Intercross router “donated” by MTS, and so you can’t set a broadcast channel for this reptile (you select, save, reboot, go into the interface and there the auto channel). When configuring TPLink 841ND in WDS mode, the current channel on which the network is broadcasting (saved in the settings) from Intercross is selected and everything seems to work until this bastard changes the channel.

There was an opportunity to try to configure a bunch of Dlink DAP-1360 + TPlink-TL841ND.
On Dlink DAP-1360 put "channel 10 B/G/N" + DHCP + WAN. (IP 192.168.0.50 did not change).
On TPlink-TL841ND enabled WDS + DCHP OFF + "channel 10 B/G/N". (IP 192.168.0.1 did not change).
From TPlink-TL841ND, a computer is connected via a cable, and I actually write from it.

I set everything up from scratch, the first router takes care of everything. Everything seems to be working, but cardsharing sometimes slows down, the second router does not distribute the Internet for a while, but then everything gets better by itself. I can't find time to look at what's going on.
