wifi router

[chronicle]

Do those "universal" wifi range extenders (the ones that are small enough to be plugged in directly to an ac wall socket) sold online actually work with any router?

I have a Converge router on the 2nd floor. Problem is, it's wifi signal is so weak that my Android TV box downstairs keeps losing wifi signal. I temporarily set up my cdrking router as an ethernet bridge to get streaming working on my TV. I need a more permanent solution to get stronger wifi signal downstairs (not just for the tv) that doesn't involve running cat5 cable around the house or through the walls.

Powerline networking?
Dont know if locally available nga lang.
