I bought a 200 AV N adapter to connect my cable internet connection to my home office LAN. It works well. Encouraged by this, I bought a second 200 AV N to cure a wireless blackspot at the back of my house (~15-20 meters from the incoming cable), and to allow me to connect a TV to the home LAN. This has not worked nearly so well. The problem is manifest as a very slow (5 Mbps!) reported transmit speed from the 2nd AVN to the AV mini supporting the cable connection. Curiously, the speed in the reverse direction is much better (~ 100 Mbps), and the connection between the AVN's is fast too. I have tried replacing the AVN and using a number of different sockets in the room, but to no avail. The problem might be caused by my electricity meter or some other local condition. My advice is to see if you can borrow this or a similar product and try it in-situ. If it works fine, you will probably be delighted with the 200 AV N.
