Excerpt: I chose the product for compatibility, since I already use a Linksys E2500 Wireless router. I plugged it and it played. I get internet access in the lower floor in the house, streaming Netflix without a hiccup.
Summary: Works most of the time. the signal will drop fairly regularly but then come back. The data throughput rate is slower than expected - though I suspect that's because of where I have the devices. The box contained 2 of the 4 port devices - just plugged the internet source into port one on one of the devices and the other has signal.
Summary: Unbelievable and so easy to use too. Tried a wiFi extender to reach my Roku (Across the house from Verizon Fios router) Still not enough to stream any video without constant buffering. Plugged these puppies in and great wired connection. The one by my TV is plugged into wall socket the other next to my router is plugged into a 6' extension cord. I thought the extension cord would nix the connection but to my surprise it worked like a champ.
Summary: 1. The mac address & password label have been removed. 2. The bandwidth is extreme low & lossing packets. (about 2~3Mbps bandwidth which means you download speed will be around 200K/S.) I did test my TPlink single powerline, and it can give me full speed (30Mbps) under the same network environment. Suggest: Don't buy it.
Summary: Like others, I got 2 PLS400 units instead of one PLE400 and one PLS400, so the picture is wrong. Also came is with 2 short ethernet cables. The "source" unit gets over 80 MB/S, but I only get 10 MB/S out of the other unit. Plug and play, thank god, because no instructions were included.
Summary: Like some others have experienced, I got 2 PLS400 units instead of one PLE400 and one PLS400. However, both units were bad as I have another set PLS/PLE units to work with. Additionally, the serial number / password stickers were removed.
Summary: So happy I bought this product. Prior to purchasing this, I was only getting speeds of about 2-3 MB through WiFi and I just couldn't deal with those slow speeds. With this adapter kit, I now get speeds of 25-30 MB and I couldn't be happier. Buy this!
