Are there routers with an external Wi-Fi interface?

Question

network hardware

Are there any such routers (or firmware) that allow you to use the Wireless interface as a WAN?
I need it to organize digital TV in the apartment.
Now there is a regular dedicated line that comes to the WAN port of the router. The router distributes this to the computer via Gigabit ethernet and the rest via Wi-fi.
For digital TV, you need a set-top box in which there is only an RJ-45 port. I do not want to pull the cable through the console.
Therefore, the idea arose to make a Wi-fi bridge, since the visibility between the router and the set-top box is direct.

Answer 1

buy a zuxel kinetic it can act as a waffle receiver.

Answer 2

In theory, almost any router should cope with this.
You need to assign an ip-address to the router in the same subnet, disable DHCP and configure WDS with the first router - then the second router will act as a repeater of the first one.

Answer 3

An access point in client mode will save you.
