TPlink router bridge mode

Bridge mode allows you to connect two routers, which disables the NAT in the modem and allows the router to function as a DHCP server without an IP address conflict.

So here is my main WiFi Internet router that sits in the main hall, which doesn't have enough coverage for the backyard and garage. I had a spare TPlink router in my home, which I used to extend the WiFi coverage to reach the garage. 

The TPlink router now connects to the main router's WiFi and acts as a bridge. I don't see any considerable performance degradation here, but yeah this will definitely increase the hops.
