Customer Questions & Answers

They work great and very easy to install.
Stephen
Also, all the powerline adapters have only ONE network port, so I'd still need a network switch to connect to 2 or more devices!

The setup works great and now I also have a very strong wifi signal throughout the house.

My house was prewired with CAT5 throughout however the Ethernet outlet in the office was across the room from the router and I did not want to string wire under the carpet to reach it. I had seen these network power line adapters before but was hesitant to buy them as some customers had expressed difficulties going across circuit breakers and electrical subpanels. I talked to Cisco/Linksys prior to purchase and they told me that they do not guarantee the PLEs across circuit breakers and their success ratio with these units is about 90% overall.

My PLEK400 units arrived a few days ago and they are working very well. The adapters could not be easier to install and in less than 5 minutes I had Ethernet throughout my power lines. These units are basically plug-and-play although I recommend downloading the "PLE400 Utility" from the Cisco site as it installs a PC based User Interface to easily setup additional security, name each adapter, check status, update firmware, etc. One of the two adapters (they are both identical) plugs to an electrical outlet near the router and is connected to the router by the provided Ethernet cable (this becomes the base unit). At this point you have Ethernet throughout your electrical lines. The second adapter plugs to a different electrical outlet providing a network connection to whatever you hook up into that adapter.

In my own application, the office, I plugged the 2 adapters into electrical outlets which are under the same circuit breaker. The second adapter (the downstream unit) is connected to the Ethernet outlet by that wall and connects to my prewired CAT5 system throughout the house.

Style Name: 1-Port + 4 PortSize Name: 200 Mbps Verified Purchase
I bought this for my home theater so that I could hook up all the internet-enabled components. I used to think that when a product was Ethernet-enabled that meant that you had to run 100 feet of Ethernet cable from your router, through the walls, and to your components. That sounded messy to me so I always looked for WiFi-enabled products. I initially thought about buying a bridge instead but my understanding is that the Powerline adapters were faster since they are a wired connection. I can't verify that but that is what I was told so double check.

I was also told that for the Powerline adapter kit to work, both outlets must be on the same circuit. I don't know about you but I am not an electrician and I really do not know what this means. So I just crossed my fingers, bought this product, and hoped for the best.

The product contains two adapters; one that you plug into an outlet by your router and another that plugs into an outlet wherever your other equipment is located. You also get two Cat5e cables which I find to be a little on the shorter side so you may want to buy a six foot or longer cable. There is no instruction manual included just a small diagram. Honestly, you don't need an instruction manual because the four-step diagram really sums up the installation process.

Here is what you do:

1. Plug the single port end into an outlet by your router
2. Connect it to a port on your router
3. Plug the other port near the other equipment
4. Connect this port to the port on the equipment

That's it, no settings to change and you will be online (assuming both outlets are on the same circuit.

Style Name: 1-Port + 4 PortSize Name: 200 Mbps
Some of the reviewers on this site may be a little confused, as Amazon is selling three different types of Linksys Powerline units; two of them are wired units and one features a wireless extension mode of operation. Note the selection box that allows you to select single port, 4 port and wireless units. Most of the negative reviews seem to be directed at the wireless unit, although there are a few complaints about the units not working unless they are plugged into AC outlets connected to the same circuit breaker. That was not the situation in my large house. I tried the 4port WIRED unit in three different areas of an 8500 square foot house; each area was on its own AC sub-panel, obviously with different circuit breakers and different AC panels in use at each end of the powerline internet circuit.

The Linksys wired units worked perfectly for me in all three areas that I tried. I just plugged them in and was up and operating with a high speed wired internet circuit within about a minute. No configuration was required, as I am only using a pair of the Linksys units. I think the button on the side of the 4 port wired unit is used to configure pairs of these power line units if you are using more than one pair of them in your house. The manual is not too clear on this.

I didn't try the wireless units, but the wired 4 port unit worked great for me and is highly recommended if you have large distances to cover, or if you are experiencing wireless network interference (usually periodic signal dropouts or slow transmission speeds) from your neighbor's wireless routers.
