Pros: - Fast connection speeds
- Pass-through power outlets (no more eating up an outlet)
- Easy set up
- 2 year warranty
- 128-bit AES Encryption
- RJ45 network cables included
- Great if you want a "wired" connection without running cables across the house

Cons: None.

Other Thoughts: I have reviewed plenty of powerline adapters and these are the fastest ones yet in regards to network connectivity. My complaint with power line adapters was that they "took" a power outlet since they cannot be connected to a surge protector and have to be connected directly to the wall. The added pass-through power outlets are a nice touch and polishes off the incomplete design of the older powerline adapters making this a completed design. The speeds are fast and will require a router that is capable of handling speeds of 1200Mbits per second.

Set up was a breeze and just requires pressing a button on the units. These are truly plug and play and were up and running in a matter of a few minutes. These also play nicely with other powerline kits. I tested them with a Netgear kit and another set of TP-Link adapters and they worked great.

If you want to have a wired connection but can't run network cable neatly then powerline adapters are great and this one is one of the best. With the added pass-through power outlet, you won't have to worry about "wasting" a plug again.

Pros: -2 year Warranty
-24/7 Tech support
-Plug and Play
-984 ft. range over electrical circuit
-128 bit powerline security
-Manual very clear and easy to follow.

To achieve 1,200Mbps you'd need devices that can achieve no less than 1,200Mbps, in other words AC networking.

Set up was extremely easy, took no more than 3 minutes in the actual process, from thereon it did not require drivers installation or any other kind of software or firmware or app, just plug and play.

In my first run I used it wired from an outlet which unfortunately had an integrated 6 outlet surge protector (according to the manual a surge protector is not recommended for this to be plugged in), not a strip but nevertheless I tried. First with the wireless connection I was getting 26/30Mbps, now wired and the surge I was getting 40/50Mbps. Not bad.
There were no glitches, no dropped signals even during busy weekend hours of the day and night.

Streaming was good, from all well known sites and cable services.

2nd step was to bring my wireless Linksys AC 1200 router to my room (I have the range extender in my bedroom but even with it I was getting 26/30Mbps, very slow considering my speeds are 75/75Mbps), so I unplugged the AC router from the main cable/router downstairs and this time I put the POWERLINE adapter in an outlet which there was no "surge protector", plug the Linksys AC router into the powerline adapter and tested the wireless speed and I am gettin 50/60Mbps (35/41Mbps lowest) average, with 61/73Mbps the highest I've seen. Dramatic improvement, now I feel like I'm getting my money's worth from the AC router and cable/internet fees.

3rd step, checking with XBOX, when my AC router was downstairs I'd get drops all the time and it became annoying so I used the main cable/router to connect but still had low signal but no drops.
With the AC in my bedroom now, XBOX live has no glitches, full wireless bars, streaming is flawless, not a single drop in signal for 5 days straight and counting.

Overall, it's a fantastic unit and way much better than to run ethernet cables through out the house, the speeds improved dramatically, never thought I could achieve them with all the wall in my house and in all 3 levels.
This unit is worth every penny and it's a great tool to expand your network around your house w/o slowing down your internet speeds.

Best part in my opinion, if your cable company provides a router, now you can have a wireless AC router in the 2nd level w/o having to buy a range extender, if you want to keep your home wires free. Now all of my 3 bedrooms upstairs I get full bars for wireless signal in all devices we use in the home.

Cons: None.

Other Thoughts: Internet in every room and every floor w/o running cables in the entire home, using existing powerlines.

***EDIT:
Been using this since October on a daily basis for more than two hours a day and I'm yet to have any issues with it, it certainly is much better than to have wires all over the house or trying to hide them, with these units I can make any outlet an internet connection outlet in the house. One of the best items I've reviewed so far, it's convenient and never have to worry about 50ft cat5 cables, kinda like wireless.

But yeah, no issues of any kind, always connected and downloads as fast as the speed is rated from my service provider.

Pros: I really like these powerline ethernet adapters. You can literally just plug them into the wall and your ready to go. I know a lot of people have complained about the speed, and I agree, its no where close to 1200mbps. However, I am currently getting about 366mbps (45MBs), which is really good, and faster than wifi. I think most of the problems folks are running into with slow speeds is caused by the wiring in their homes. My house was built in 1994, so its fairly new electrical and I've seen a very stable connection over about a 100ft run.

Cons: The advertised speed is pretty inaccurate, though these still are capable of performing much faster than wifi.

Other Thoughts: I'd recommend you give these adapters a try if you have a newer home with modern wiring. Its so much easier to just plug these into the outlets than run cat6 throughout your home.

Pros: One of the pair work great! Was able to add a wireless extension into the network and it works flawlessly.

Cons: The second passthrough module has to be consistently reconnected. It seems like some "green" power saving tech kicks in, and then loses the connection. They are junk is too harsh (but all I can think of at the moment), and I would have returned the entire kit had the wireless module not connected right away, with no other problems.

Pros: 20 MB/s (160 mbps) performance . Has a much needed power pass-through because it is bulky.

Cons: Connection drops out over the same 50 feet circuit a few times a month, and TV recordings being carried over the connection have holes in them. The adapter is also rather bulky.

Pros: Worked great right out of the box.. it even works plugged into an el cheapo powerstrip surge protector (which was necessary due to the size of this and a lack of space at the one outlet i needed to use)

Cons: Size. It kinda eats up an entire outlet. To work around this I plugged it into a cheap surge protector. This might not work for everyone.

Other Thoughts: Fantastic. Idiot proof.

Pros: - Significant improvements in speed.

- Significant improvements in consistency of operation.

- Significant improvements in firmware.

- Speeds achieved are a far cry from "1200" Mbps, but the speeds are consistent and may be superior to WiFi. The plethora of WiFi that now exists and folks thinking/keeping the transmit power to max (when low or medium would achieve maximum possible speed) - often makes WiFi less than optimal.

- Best performance when both units are on the same phase circuit.

Cons: - Still not 1Gbps wire speed.

- House 'wiring' still a significant limiting factor. (see other)

- 'Power hungry' appliances (noisy ones) can have a significant impact.

-A 'very noisy' light bulb on the circuit can present a ~30% drop in speed.

- Excessively large to the point that it's "one item" per duplex outlet for electrical use.

- Lack of activity indicators.

- Instructions need to be reviewed for accuracy.

- Speed should be advertised using realistic value. Max upload + max download speed isn't helping the consumer.

Other Thoughts: - Electrical wiring codes, while intended to be 'beneficial' never took into consideration that the wiring might also be used for data transmission. Thus, the wiring itself can be a hurdle.

- When tested on a dedicated run that was breaker panel to an outlet to another outlet, roughly 75+ feet in-between outlets and nothing attached but the units - achieved excellent (and consistent) speeds. Between breaker and first outlet a power line conditioner exists that also filters out 'noise' and nothing else on the circuit (unusual for most cases). It's a scenario that most people likely wouldn't have.

- Even certain types of lighting can present hurdles. Example, an inexpensive bulb created a lot of noise (reduced speed) vs. a more expensive 'better' bulb (generated less noise) had less impact impact (faster speed).

- If you're looking at using this for wired networking it's definitely an option. The technology has gotten far better (than it used to be), still not perfect.

- While many factors can impact it, one can't expect excellent results if there's a lot of noisy appliances/lights on that same circuit. Depending on where you live and how densely populated - may increase the ambient noise coming into your house.

- To get the most from this type of technology, it requires some consideration and some testing, likely some spend (better quality items on that circuit) and perhaps a bit of luck to find the right circuit(s), unless you know which circuit(s) are your best route.

- Would certainly recommend, but that comes with some effort - it's not "plug and go".

Pros: MUCH faster than older Rosewill 200Mbps adapter
Easy to install/setup

Cons: None

Other Thoughts: Apparent issues between TDS router and old 200Mbps Rosewill powerline adapters limited download to ~36bps and uploads to ~39Mbps (go figure - right - never figured out why). Since I have 100Mbps service and can get 98 Mbps wirelessly, I ordered these for a more stable connection to my desktop computer. Once installed download speed jumped to 98Mbps and upload stayed 39MMbps. Do not know upper limit, but at least for 100Mbps service - they WORK!!

Pros: Installs easily

Cons: Drops the signal coming from the next room

Pros: Very easy to use, just plug them in and they'll connect to each other; literally zero user set-up required if you want.

Very reliable; I've had these bridging to my detached garage about a hundred feet away. In the garage I have three security cameras streaming 24x7x365, and the DVR that records them automatically fires an event if even a single frame drops. After three weeks of continuous testing, not even so much as a single dropped frame.

If configured correctly, these will play very nicely with other powerline adapters (PLAs). I've had a pair of 500Mbps zyxel PLAs (these are 600Mbps, by way of comparison) going to my garage for a few years now, and they've been similarly fantastically reliable. So the first thing I did was pair one of the TPLink adapters to my existing PLA network (so it was an A-B-C network). The PLA paired no problem. Without taking down the garage cameras I then shunted all sorts of files through the powerline network, averaging about 200Mbps throughput. (Throughput on a PLA network is shared among all devices, so this was within reasonable expectations.) So clearly the TPLinks and the Zyxels were happy co-existing on the same PLA network. (You cannot have two or more PLA networks on your electricity lines at the same time or throughput will go into the trash -- pro tip!!!) I then added the second TPLink to my existing PLA network, and tested it similarly. As a last step, I replaced the original zyxel 500Mbps PLAs with the 600Mbps TPLink PLAs, and ran them exclusively for a few weeks. Not even one single frame dropped, and those cameras are pushing about 4Mbps 24x7x365!

Cons: These are a bit tricky to get to connect to other powerline adapters (PLAs). TPLink includes a quickstart flyer, but it's not really all that clear what sequence of buttons you need to hit on the device to get it to join the network. Worse this sequence of buttons doesn't seem to be standardized across PLAs. I eventually stumbled upon the sequence (it wasn't *that* hard) but it didn't seem to match what was on the quick start guide.

No network activity lights. Unlike the Zyxels which would show when data were flowing through them by blinking the network light, the TPLinks are content to show absolutely nothing. They will show that a PLA network exists, but that's it; you have no idea if there is any data actually flowing. After coming from the Zyxels this is a significant step backwards; I could tell with a glance at the Zyxels not only are my cameras connected but actually transmitting data. With the TPLink all I know is that there is power in my garage and the link is up, I have no idea if there is any data actually flowing.

Big, and bulky. I don't know why, but there seems to be a universal template for first generation PLAs and it always seems to cover the adjacent plug. (Here my Zyxel and TPLink adapters are equally abhorrent.) It somewhat mitigates by having an electricity pass through socket, but it's a case of robbing peter to pay paul; you gain one socket but lose access to another. Much better would be to make the bezel on the unit a lot smaller so that in addition to the pass-through socket you could also use the adjacent socket!

No PoE. This isn't really a knock as a big wishlist item; wouldn't it be great if this unit supported PoE, so that if you had an access point all you needed to do was plug in the data cable and go? Sadly, no. (Well you still can with a power injector, but uuuuuggggllllyyyy!)

Speed? C'mon. All PLA manufacturers are guilty as sin about this, and TPLink is no exception. These are 600Mbps units; the "1.2Gbps" comes from counting the upstream and downstream in simultaneous use. No other network technology rates their network speed this way, so it's just dishonest. With that said, these 600Mbps units were slotted directly in place of where some 500Mbps units have lived happily for a few years. Was there a speed improvement? Ehhh, maybe. It's hard to tell; the software says yes but it's very hard to measure that accurately over a PLA network.

The software kind of stinks. It works *okay*, but is finnicky. The Zyxel software is much better. With TPLink's software, if you're not DIRECTLY connected to a PLA adapter it refuses to do anything. With Zyxel's software, as long as you're on the same layer 2 segment as a PLA device then it can talk to it and configure it. Much better design, and there's absolutely no good reason for TPLink's limitation. It prevents you from checking on your PLA network's health from anywhere except being directly attached to one of the PLA adapters dir

Other Thoughts: While you can plug these into any electric outlets in your house and they'll work, you'll get much better performance out of them if you do a little detective work on your electricity beforehand. (Or ask a very knowledgeable electric-minded friend!) PLAs dirty little secret is that they work great *as long as* all of your PLAs are on the same electric phase. Typically houses are wired with two phases, A and B. If both your PLAs are on phase A, great! If both your PLAs are on phase B, great! If one PLA is on phase A and one is on phase B, PLAs are going to have a hard go of it. They'll still *work*; you'll still get a connection it's just not going to be a great connection. The problem is that the signal from one PLA has to go all the way out to your electric meter, go through your electric meter, then back into your house on the other phase to the other PLA. That adds a lot of points of failure for the PLA network, and will considerably degrade its speed, latency, and reliability. You'll often pull sub-50Mbps if your PLAs are on different phases when if they're on the same phase you'll get between 200 and 600 Mbps.

(Please note that when I'm talking about phases, I'm not talking about circuit breakers. If you're looking at your electric panel, every other breaker from top to bottom is on an alternating phase. So row one's breakers are phase A, row two is phase B, row three is phase A, row four is phase B, etc.etc.etc. That's the quick and easy way to tell which circuit is on which phase.)

Latency on these units is great. When both PLAs are on the same phase I regularly get between 2 and 4 ms when pinging devices over the PLA. When the PLAs are on different phases, not only does the latency increase dramatically (into the 100ms range), but throughput goes way WAY down. This is to be expected; there's really only so much a PLA can do. But it's something to be aware of when planning out your PLA.

Overall these are just as reliable as the 500Mbps Zyxels that I replaced. I really wish they showed actual activity with their network indicators like the Zyxel units, but otherwise they're fine units.
