Review: Excellent 200Mbps adapters--don't waste your money on most 500Mbps on the market - UPDATED ON MARCH 3, 2014: I recently bumped up my internet speed and began running some speed tests to verify this. I was surprised to find out that the throughput over these powerline adapters had dropped by over 50% since I originally reviewed them. I've tried resetting them and reinstalling the firmware, but the problem remains. The only thing that may have changed was the fact that I accidentally pressed the "encryption" button on one of the adapters a few days ago (around the time I increased my internet speed with Comcast), but resetting the adapter should have cleared that. The adapters still push around 90Mbps in the same room, but this number drops significantly as I move the adapters away from each other. Where I was originally getting over 90Mbps with the adapters on different floors, now I'm getting around 40Mbps with the adapters in the same position. Since I now have a 50Mbps internet connection, I'm a bit disappointed in that these adapters are now the bottleneck. I'll look into the issue some more and may contact support, but I won't knock off any stars off my original review until I find a cause. ORIGINAL REVIEW FROM NOVEMBER 19, 2013: This review is for the 4-port Linksys Adapters, and not the wireless extender. Not sure why my review is tagged that way. Just some quick background info that may help some users: There are basically two ratings for powerline adapters: 200Mbps and 500Mbps (a few other speed ratings may be found, but 200 and 500 are the standards). I've used a few different powerline adapters over the years, and believe that currently, the 200Mbps-rated adapters are simply a better purchase than most the 500Mbps-rated adapters. Most of the higher rated adapters are pretty much a gimmick, in that while they are designed to meet the specifications for 500Mbps over the powerline, the adapters are often equipped with 10/100 ethernet ports. This basically means that while they could potentially push data at 500Mbps over the powerline, the bottleneck is the actual ethernet port on the adapter, which is limited to a measly 100 Mbps. I don't know if this is a cost-saving measure or a technical issue, but it looks like most manufacturers design, and market, their powerline adapters this way. I've also found that the 500Mbps adapters are more sensitive to more power-hungry devices on the same circuit. For example, if you have a power hog like a home elevator or a gym-quality treadmill, the 500Mbps may be more sensitive to that when in use. If speed over the powerline is truly what you're after, by all means spend the money and get a 500Mbps+ adapter, but make sure it has gigabit ports (and definitely use Cat 5e or 6 ethernet cables), or else you're just wasting your money. Along with the Linksys, I also considered the TP-LINK TL-PA4010KIT AV500 Nano Powerline Adapter Starter Kit, up to 500Mbps . It has great reviews, an attractive price, and can be purchased with a gigabit port. Unfortunately, TP-Link doesn't sell this model with a 4-port switch as Linksys does, which is why I went with the Linksys. If I only needed a single port, I would have gone with the TP-Link. Now onto the Linksys: I ended up purchasing the 4-port adapter kit. As is usually the case with powerline adapters from most of the big manufacturers, the setup was quick and simple--literally plug and play. As for real-world speed, I ran some iperf tests on my network (two Macs and an Asus RT-N16 router running Tomato firmware)... here are the results: - Both clients wired into the same 4-port powerline adapter (other adapter not used): 93.3 Mbps (my theoretical max) - Both clients wired into different adapters in same room, different outlets: 90.6 Mbps And with the adapters on different floors - Both clients wired, no router: 90.2 Mbps - Both clients wired, with router: 90.0 Mbps The speeds were very consistent in my tests--far more consistent than pushing data over wireless. After reading reviews of some 500Mbps adapters on the market, my test results showed that my speeds usually exceeded the ones reported by reviewers of many 500Mbps adapters. And a side note: don't pay attention to reviews using results from SpeedTest.net or other internet-based speed test service as a good measure of network adapters. Internet speeds have nothing to do with your home network speeds. Overall I'm very happy with the speeds, setup and consistency of these adapters. It's too early to tell if the adapters will keep up this performance over time, but so far it's very promising.
Review: Works Great! UPDATED - I have been dealing with networking in our household for years, and I think this is the very FIRST product that simply worked right out of the box--no configuration necessary. I had considered getting a wireless network extender (Linksys RE1000), but decided against it, given the uneven user reviews it received. Since I really only needed to get better network connectivity in one small area, this alternative made sense. I connected the one piece of the PLSK400 to my Linksys E4200 at one corner of our house and plugged the other piece into an electrical receptacle at the opposite corner on a different floor. My son's Xbox connection is now much improved, even better than the wireless connection he experienced playing it in the same room as the router. Now he can keep his Xbox with the big screen TV and get great performance. And since I bought the model that has four ports, I can also connect the Wii and the Blu-Ray player as well, with one more port left for something else in the future. I don't usually review stuff, but felt compelled to submit a positive review for a product that made it so easy to extend my network to the furthest corner of our house. EDIT: I built a new computer, and wanted to put it down in our family room, where I also had placed the 4-port portion of the kit. Unfortunately, the desk is in a part of the room where I can't connect to the 4-port powerline adapter I'm using to connect the Xbox. I searched for information on whether buying another kit would extend the powerline network using the same unit that was hooked up to my router. After not finding anything, I finally just decided to go ahead and purchase the Linksys Powerline AV 1-Port Network Adapter Kit (PLEK400), which is the same as this kit but with only 1 port in each of the two units. I couldn't find any source where I could simply buy one unit alone. After receiving the PLEK400 kit, I plugged one of the units (they seem to be identical) into an outlet near my new computer, hooked up the computer, and it connected to my existing unit next to my router with no problem. Since the kit came with 2 1-port units, I use the other 1-port unit to connect my laptop from a different area, when I don't feel like using the wireless network. All worked flawlessly together, again with no configuration necessary! Now that I have owned both the PLSK400 and the PLEK400 kits for several months, I can again affirm that these have worked beautifully for our family. However, I have found that every once in a while (maybe every 2 weeks or so?), I need to unplug them and replug them to "reboot" the powerline network. The powerline network seems to slow way down or quit working altogether if it hasn't been restarted for a while. Instead of waiting for that to happen, though, I usually simply restart it (by unplugging and replugging all units) when I find it necessary to restart our router and cable modem. The router or the cable modem need to be restarted more often than the powerline units, so the slowdown that sometimes had occurred never happens anymore. Because this is easy to do when the rest of the network needs to be restarted anyway, I don't feel this should detract from my initial 5-star rating.

## Questions & Answers

**Q: My Verizon DSL modem/WiFi router (brand:Westell) is located in my 2nd floor of my home. The wifi signal is very weak to my basement where my TV and streaming devices are located. Will this network extender resolve my problem? Has anyone used it with a Verizon DSL modem/router and found it working fine?**
A: I am also with Verizon and have a Westell branded modem. I use a Netgear WNDR4500 router. The power line unit is connected on the APC on the gound floor and the receiver is on the second story off a surge protected outlet. The unit works very well as I get a direct connection to my desktop and the Kindles, Nooks, iPads, phones, etc all receive a good connection. The desktop only received about half the broadband that a pc connected via cat5e, but it is adequate for surfing and homework. If the house wiring is in good condition you should have no issues with the unit.

**Q: Do both units have to plug into the same electrical circuit?**
A: No, They do not have to be on the same Circuit.  However... they do have to be on the same phase of your electrical box.  Phases usually alternate like so:  Phase1: breaker 1 & 2, Phase2: breaker 3 & 4, Phase1: breaker 5 & 6, Phase2: breaker 7 & 8, Etc...  the reason for this is there is no continuity between the phases (they are not connected to each other) therefore the signal from plug A on phase 1, will not be connected to Plug B on phase 2.

**Q: Does this kit come with cables?**
A: What's in the box? This product comes with everything you need to connect up to 4 Ethernet enabled devices to your network over existing AC power outlets. *1 Linksys PLE400 Powerline AV 1-Port Network Adapter *1 Linksys PLS400 Powerline AV 4-Port Network Adapter *Quick Install Guide *2 Ethernet Cables (the included Cables are only be 3 foot)

**Q: Will it work if plugged into a powerstrip/surge protector or does it need to be plugged directly into an outlet?**
A: Hi J. BolusIt is not recommended to put a Linksys Powerline device behind a powerstrip or surge protector. Although there have been users that were able to successfully make it work behind surge protectors, we still recommend plugging Powerline adapters directly into a power outlet.

### ⭐⭐⭐⭐ Does what it says and it has worked for me so far
*by D***N on April 18, 2013*

After my old set of powerline adapters broke, I checked a few different powerline adapters before settling on this one. I have a linksys router and I've been happy with it so I figured I'd go with this one since it also has good reviews. My setup: I have the base plugged in to the modem in the master bedroom and the other end is in one of the bedrooms to connect my Xbox (they are on the same floor, but different circuits). I have a pretty good router, so my WiFi speeds are good, but they are a bit unreliable for online gaming. Even though this transmits the connection slower than my WiFi network (still good enough for online gaming), it is more reliable than my WiFi. For this reason it works brilliantly for when I'm on Xbox Live. Setup was super easy and went exactly as the instructions said. I plugged in the base (the one with only one ethernet port) directly into a wall outlet in the master bedroom and used the supplied ethernet cable to connect it to my modem. I then plugged the other one (the one with four ports) directly into the wall outlet of the room where my Xbox is. The adapters made a connection pretty quickly (in maybe less than a minute). I then used the other supplied ethernet cable to connect the four port adapter to my Xbox. I fired up my Xbox, chose the wired connection and I was set. I also use one of the other ports to connect my laptop for bigger downloads. I took off one star for these two reasons: as stated earlier, the connection is much slower than I expected them to be (though they are still fast enough for Xbox Live, which is why I bought them). The adapters I had before were faster even though they were quoted for a slower speed than this one says it'll go. And the second reason is I still sometimes experience weird drops in speeds for a couple of minutes. This will happen even if no other devices are connected to the network at the time. I'm not sure if it's my internet or the adapters, but I am leaning toward the adapters since it didn't happen before. Again, this isn't a big deal as it only lasts for a minute or two before going away and it doesn't happen regularly. Overall, these are pretty decent. If you have a good router then the speeds from this will be slower than what your WiFi gives you. But the connection is pretty reliable and the installation was a breeze. So for that I would recommend this powerline adapter.
