Wi-Fi finishes badly - how to strengthen it?

Question

WiFi

I am sitting in a room that is far from the reception, and the router, apparently, is only there. How / how to amplify the signal?
Do not stretch the wire - my possibilities are limited by the number itself. You need to use the Internet from your phone and computer, but only via Wi-Fi.
I'm thinking about NanoStation in AP-Repeater mode, but I have two questions:
1) Will NanoStation work as a repeater if that router does not have (or is not enabled) WDS? I can not find out what kind of router is there and how it is configured.
2) What kind of device would you recommend (so that without unnecessary functions, but with a repeater mode and an Ethernet port, just in case)? NanoStation Loco m2?
PS: For some reason, I think that the solution should be directional (antenna) and within one box.

Answer 1

If you put a repeater in the room, then you will only amplify YOUR signal.
And you will receive the same weak.
It is much easier to arrange with the hotel to move you to another room .
