If you have WIFI dead zones in your house this may be a solution.
The WIFI router supplied by our internet provider isn't the most robust so, I've never been able to get a WIFI signal in the shop. Even though, the shop is only about 100' from the router.
Several different types and brands of extenders were tried and returned. Thank you Amazon. I finally happened on to this TP-LINK AV500 range extender that uses your house wiring as a transmission medium, thereby eliminating problems caused by walls, metal studs, distance, etc.
There are two components, an "adapter" that is connected to the router and plugged in to a nearby electrical socket, and the "extender", plugged in to a socket located in or near your dead zone. It's optimum if both sockets are on the same circuit. In my case, I used a socket in a wall closest to the shop. It's not on the same circuit but, it works.
Now, I have WIFI in the shop.
