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: Delivery was on time and price is $24.95 not bad. When I bought the 3 pairs and placed the order I thought one main PLE400 and one PLS400 for each pair based on the posted picture. I did not pay attention to the title listed 'AV 4-Port Network Adapter Kit'. So I got 6 PLS400. Fortunately, I already have PLE300 in use. I connected first PLS400 to PLE300, it took time. Others were easy to connect. If PLE300 works normal all the sub PLSs are fine.
Summary: I have a home media server where I stream 1080p movies at > 8000kbps. This really taxes a SOHO wireless network that is already dealing with handling 15 devices on it. I decided to go Powerline as it was a simple method of dealing with the issue. Everything sync'd up great and took off. Every now-and-then (think once a month...maybe a bit less) I have to re-sync the Powerline gear..
Summary: Bought this device on sale for 49.99 + tax hooked it up not knowing if it would work in my house. Sure enough pushed the sync button on both of them and was online within seconds works wonders with my Dlink Router also.
Summary: I agree with many of the positive comments that other reviewers have posted, but you should be aware that you cannot purchase additional receiver units outside of the kit that contains both the transmitting (PLE400) and the receiving units (PLS400). Despite the product description ("Easily add more devices to your network by plugging additional adapters into electrical outlets"), I got this in an email from Linksys technical support on 1/3/14, "Please be informed that...
Summary: I think its wonderful that no matter where the modem is I can connect to it without using wireless. Although, I get a direct connection I am not receiving the bandwidth that our package offers or that the power line advertises. But overall a good product, would recommend to anybody! I would given a 4 1/2 stars if I had the option and five stars if there wasn't a lack of bandwidth through it. Still a Linksys fan, 10 year customer, its the better brand on the market.
Summary: I spent quite a while fighting with this unit, I thought it wasn't going to work for me and that the wiring in my building was one two circuits. It turns out that these don't work through powerbars (or maybe just surge protectors). After I plugged them directly into the wall outlets, they connected just fine. The prongs don't fit tightly into the wall outlet. So it's hard to get them to sit straight in an outlet.
Pros: Very clean, fast speeds, easy to set up once on a viable line.
Cons: Doesn't work through power bars, slides around in outlet.
Excerpt: If your computer, tv, or any type of devices that need Internet, this is the product you should get. You get Internet out of the power outlet anywhere in the house as long as you have the second adapter.
