Summary: They work for about a week and then stop communicating with each other. I unplug one unit for about a minute, then plug it back in and a few days later do it all over again. Somewhere I read this may be due to a power saving function. However I can't find a setting to disable it. And don't ever think D-link support will help. In fact I really believe that department is a hoax. Tech Support never calls me back or responds to emails. Buy this and you're on your own.
Summary: The product I bought PowerLine AV type DHP-310ABV is not working at all. I am tired to install this product two days long. PluNPlay is absolutely not working. I don't know what I should do with this product here! I have contacted [...] but even the type they don't put as the item. It's useless product, dlink doesn't provide an email where I can write my complaint! Maybe Amazon can help?
Works great with my exising D-Link PowerLine setup

Summary: This is a great unit but be aware that IF you have a high amperage draw on the same circuit, it will reduce your download and upload speeds. Specifically, my Dell power charger for the Dell laptop, drops the speed. Also, if you have a UPS on the same circuit and there is a power drop which forces the unit to recharge itself, then during that recharging the PowerLine d/u speeds with temporarily drop until the UPS is fully charged.
Summary: so it worked intermittently for a short while - now it has stopped all together - the smaller plug has given up the ghost after 3 months, no lights on it illuminated. i suggest you buy the other brand aztech which worked for years in my old house, never again dlink.
Summary: I bought this plug to add to my existing Dlink AV 500 setup. I needed a compact plug for my IP camera whose wireless g connection was acting up. Instant plug and play setup. Works great. I also tried this plug with my Samsung Smart TV and streamed 1080p movies from my desktop without any issues or pauses.
