Summary: Very frustrated with these devices! I purchased the 307 starter kit (includes two 306AV units, 2-ethernet cables, and utility software) at the end of Jan '14. At first they worked O.K. Right out of the box I put one of these next to my router and the other one in an upstairs bedroom.
Summary: I tried for several years to be able to use my computer when I visited my Dad, but a lot of stonework and things blocked the wireless router transmissions. I kept trying stronger and stronger routers - a waste of money. I read many reviews of the D-Link Powerline and then a picture came together.
Summary: I've had these for a couple of years. I use them to communicate between my DirecTV receiver and my internet connection. They work quite well and are very fast. When I first installed them I had to reset them several times, but the instability seemed to resolve itself.
Summary: My friend suggest internet over electric lines. My TV in family room was connected wireless and YouTube would be slow, jand kids too complained about not able to play games online. This solves the speed problem.
Summary: I have used these adapters for several years to bring our 8Mbps internet connection from an outbuilding where the modem is located into our motorhome, and now our house, over the power lines. We get the full 8Mbps speed with no noticeable effect from the adapters.
Summary: This adapter kit works without any further set-up. I even used an extension cord to plug it in and it works perfectly well. This is all you will need if you want to take your internet connection from one room in the house to another without having to install wires. Great and easy to use invention!
Summary: I bought four of these and they work great. I can tell the difference from wireless big time. I bought it primarily for my son who's room is in an area of the house that gets poor signal, even with a router extender.
