I just went through this. I had two routers in a bridged configuration so I could wire my tv into the second router without having to run cabling all over the house. I have a three story home, so running copper was a no go.
The secondary router started dying, so I needed to replace it.
Did a bunch of reading, and I ended up buying new routers, and I went with Portal wifi. They can use bridge or mesh. I went with the mesh, and now I have great coverage and the price wasn't too bad.

Setup takes about ten minutes, and you don't need your neighbor kid to do it.
