How to set up two routers?

Question

System administration

There is a Mikrotik 2011Ui AS-RM, it has a hotspot configured (configured according to this manual www.lanmart.ru/blogs/mikrotik-hotspot/). hotspot is set up so that a page is displayed, the user clicks on the entrance and thus gets access to the Internet for 3 hours.
BUT there is no wi-fi in this mikrotik model.
Found an old TRENDnet tew-651BR.
as configured:
1) a provider cable is inserted into the 1st port on the Mikrotik, a wire is inserted into the 9th port that goes to the network station. hotspot works, after pressing the Internet is.
2) I insert the provider's cable into the wan port of the tew-651, and from the 1st port the cable goes to the network station. Inet is.
what i want to achieve:
insert the provider's cable into port 1 of mikrotik, a cable goes from the 9th port of mikrotik to the wan port of tew-651. Further, the Internet via hotspot should be both via wifi and via wires.
problem:
the above chain does not work. my guess: when I knock on any address from a computer or via wifi, it does not have access to the Internet .. I knock on a local address, but on tew-651, but on mikrotik.
Question: how to set it up so that everything works. As I understand it, you need to configure tew-651 so that it transfers everything to mikrotik .... or it must have other uns .... in general, knowledgeable people, I ask YOU for help.
PS In other words. There is a mikrotik with a configured hotspot, you need to connect 1+ simple wifi routers (points) to it in order to distribute wifi ....
UPD: I changed the port to tew-651 and it started working, but when you log in at least on one device, everything works automatically on others.

Answer 1

So, from TEW you need to make a transparent bridge between wired and wireless environments. Now this is clearly not the case, so let's figure it out
1. Connect the cord with Hotspot from Mikrotik to any local TEW port (ie from the second to the fifth)
1.2. We set the type of WAN connection to any, because WAN is not involved at all
2. Disable the built-in DHCP server in TEW (LAN & DHCP Server tab in the settings)
3. Set Wi-Fi to the desired security mode and range.
4. Are we making sure in HotSpot? that there is authorization by Cookies
5. Profit
