Two Routers compared

A comparison between the TP-link TL-WR40N

and the D-Link DIR 645 Smart Beam

Both routers are of about the same age (not brand new, but each about 2 years old.)

The wifi strength of both routers is equally weak in the furthest room in my apartment and the smart beam feature of the D-Link is not an advantage, perhaps because of the particular layout of the apartment with its many concrete walls. I use a repeater to get over this problem.
