I Bought a TP-LINK TL-WR840N few days ago and I must say I'm satisfied with my product. Making connection was easy. They gave all the necessary drivers and instructions which made the process very easy. What I liked have the router is:
1.Connectivity is strong even you are 1 block away from your home.
2.Bandwidth is high and speed you get is continuous and undistorted.
If you are looking for a high range router, then you should go for it.
