I want to have a better wifi signal in the kitchen.  It's currently very weak from the main router (a BT Hub4) because of walls, etc.
I have an ethernet/RJ45 cable going from the main router into the kitchen.  Which product/s should I look at from the the tp-Link range?
NB that I can't use powerline devices (different ring main, and RCDs in the way), and I don't want a simple wifi receiver repeater as the ethernet is much more secure.  Also be good to get a product that doesn't take hours to set up and get to work!
Many thanks.
