Have the part bought in order to extend my wireless into the garden. If it works and once everything was connected to the WPS button, the device shows a very large wireless icon on the received strength of the wireless network to be extended. The display I find it very successful. The connection had lasted several attempts, but eventually worked out yet.
The reason why I did it but then returned the set of TP-Link, which I ordered at the same time. This has both the repeater and via its own Lan much passed into the garden at the same location.
Conclusion: Coverage not great much larger though less 2 walls.
