Summary: This refurbished unit failed to work out of the box. Also purchased a two-unit pack that worked perfectly. The refurbished unit probably was returned because it wasn't working, but the refurbisher failed to detect or correct the problem.
Summary: The product seems to work, now that I have the units connecting. This may be a first world problem of my house size, but I have had some difficulty with getting the units to connect when I tried to set the security while they were in different rooms. Once I moved the units to the same room and used the "RESET" button, instead of the actual sync button, they connected to each other and I was able to then move them to the different rooms throughout my house.
Summary: These reasonably priced, quickly delivered units are absolutely the best thing since sliced bread! Ease of installation, speed of throughput, reliability of connectivity, great LED information bar - - - wonderful tool.
Summary: I purchased 2 of these for my new home. It worked ok, does not get anywhere close to the 200 mbps let alone the advertised 500 mbps. I knew this before hand based on reviews. But I'll take 59mbps considering that the Netgear Nano 500 units I tried prior to these refused to connect. The units are on separate levels about 40 feet apart. Simply plug and play, software worked. Netgear software did not work.
Summary: This product works very well. But there are a few VERY important restrictions. You MUST make sure the adapters are located on the same electrical circuit panel. I found these adapaters to work okay in my installation, but ultimately I returned them and purchased additional long range and super long range network extenders, access points, and bridges.
Summary: Once the product was set up properly I loved it. It is small and effective without the normal extender's (repeater's) ugly wires. Superb range. Unfortunately the support was terrible. Can you imagine spending hours with level one support and not have them capably advise how to get the product up and running? Then I was escalated to level two who said I had the wrong d-link products as they were not compatible (d-link sales recommended these products to me).
Summary: I ordered this item along with the D-Link PowerLine AV 500 Adapter Kit (DHP-501AV). I opened the kit first, tested it and it worked great. I wanted to install a second device with this adapter and when I picked up the box, I noticed there was no shrink wrap on the box. When I opened the box, it was obvious that this should have been sold as an open box item. The cable was just wadded up, the protective plastic bag for the adapter was missing, etc.
