TP-Link TL-PA201 Ethernet Over Power Kit Review

Streaming HD Video
A quick test was carried out to test 1080p HD video streaming between two computers on the network. A 24000kbps video was accessed and played on the PC connected via EoP, and then tested again via wireless. The result was clear. EoP handled the playback with no issues whatsoever. The frame rate was smooth, and the audio was perfect. On the other hand, the wireless connection would cause an irritating stuttering in both video and audio. This was to be expected considering the difference in throughput speeds.

Software
The software isn't particularly important to the functionality of the kit. It allows control over Quality of Service (QoS), restriction of EoP access (in addition to the default 128-bit AES encryption), and diagnostic information such as throughput speeds. If you're going to purchase more units to facilitate other computers on the network, the QoS features may be of interest. Unfortunately, the software does not work on Windows 7. Hopefully this will be fixed soon.

Heat Output and Power Consumption
Some users are concerned about the heat that EoP devices are known to generate. The TL-PA201 fairs well in this regard. Even with uncomfortably hot ambient temperatures, the kit never gets hot enough that it's uncomfortable to touch. It shouldn't get any hotter than any other wall wart transformer you may have laying around. Each unit draws no more than 6W of power according to TP-Link's specifications.

Instruction Manual
The instructions are clear and concise. Most consumers have come to expect pidgin English manuals from Chinese manufacturers, nonetheless, the TL-PA201 instructions are reasonably well written.

    How much did you pay for it? Very good. A question though, can this be used in any house?

  • http://www.cyb3rglitch.com Vito Cassisi

    I paid $147. It can be used in pretty much any house, even across different phases.

    phases?

    Great write up on the TP Link kit and EoP in general.

    I was doing work experience in Harvey Norman over the past week and I saw one EoP lol. only 1 :(

  • http://www.cyb3rglitch.com Vito Cassisi

    Harvey Norman aren’t exactly known to stock decent computing gear. And they’re expensive! :)

  • http://www.sparky13.co.cc dextras

    Well they’re expensive until you bargin with them. Though they have an awesome wii bundle at the moment. It’s below cost :) So they will try to sell warranties and such with it :)

  • http://www.cyb3rglitch.com Vito Cassisi

    The Wii is overpriced to start with. :P

    I guess they have their own little niche, so they can charge whatever they want.

    Its not explained as a feature in the manuals but I found that if plugging the adaptor directly into a power point is a problem because of its size, you can remove the power connection….its modular, as its designed to be interchanged with UK and US plugs.

    Just press the plastic catch below the plug and then slide the two prong attachment upwards (toward the top of the adaptor). Once removed, you will see a standard 2 pin power connection.

    You can use a standard 2 prong power cable to plug into the adaptor, giving you the freedom to use it on double power points without obstruction.

    Some people might suggest that this will degrade performance because of the added cable, but if you think that adding another 1 meter or so to the total cable length of maybe 10 – 50 metres of cable that is contained in your house’s wiring then I think you are kidding yourself.

    Nice tip! Cheers. :)

    has anyone had problems with recently purchased PA 201′s not working with earlier PA 201′s?

    I’ve just purchased a third pa201 to add to the pair of adaptors purchased 3 months ago.

    The new adaptor is suffering random dropouts. The configuration utility frequently doesn’t see the new adaptor and at times I’ve have to leave the unit unplugged for an hour or more before being able to successfully use it.

    I returned the first adaptor to the retailer for an exchange. Got another new one in a sealed box but it behaves exactly the same way.

    What I have discovered from the diagnostic log is that the new adaptor has a much later firmware revision than my original two adaptors.

    The original adaptors are dated firmware: 20070816-FINAL-BL-C

    The new adaptor has firmware dated: 20090501-FINAL-C

    I’ve also noticed that the Ethernet light on the new adaptor is RED and the original adaptors its RED.

    It looks as though the adaptors have gone through some recent updates and don’t play well with the older revisions.

    Any care to offer some input or experience with this problem?

  • http://www.cyb3rglitch.com Vito Cassisi

    Interesting. Unfortunately I don’t think there’s a way to update the firmware. Have you tried contacting TP-Link for assistance?

  • Elio

    Spoken with TP Link support. They don’t have an answer to the probem and indicated that they have not had any similar problems reported.

    They claim they will look into the issue and give me a response at some point in the future. In the mean time, I can’t use this adaptor. The retailer is not going to keep changing adaptors and I’m concerned that if I want to buy more adaptors in future to expand my network that I’m going to have compatibility issues.

    Just to be clear. I’ve tried all possible fault finding, including swapping the PA201′s between electrical outlets where they have been working perfectly however, the problem always follows the new adpator every time.

    Maybe I’ve just been unlucky enough to get a couple of dud adpators.

    Tech support claimed that they don’t have any firware updates available for the PA201′s at the point in time.

    Hi Vito,

    Having a problem with my TP-Link TL-PA201 Powerline Adapter.

    The PowerLine LED isn’t lighting up when connected to the electrical outlet.

    Any idea what the problem is?

    Thanks,

    Vimal

    Have you tried connecting both units close to each other?

    Thanks so much for this review! I searched everywhere for this kind of information, so glad I found it!.. I ended up buying the Netcomm np201av set, they’re fantastic. I highly recommend them for anyone like me, who dislikes the instability of wireless (especially in FPS games) but can’t go running ethernet around the house. The wiring in my house is reasonably old (15-20yrs) and according to the np201av, I have a low speed connection (shown by a red light, rather than amber or green) But it’s still hitting a consistent 20Mbps which is absolutely fine for my 6Mbps broadband connection. Best of all the connection is stable! 3-7ms range rather than 1-2000ms given by wireless. Thanks again for this informative review!

    TL;DR. EoP is great for gamers who hate wireless but can’t run ethernet cables to the computer.

    hello i have the same problem…have you find a solution ?

    thanks
