    does this come in a pack of (1) or (2)? Is it a mating pair for $24.99? The kit description suggests only one for the price.
    A shopper on Nov 23, 2016
    BEST ANSWER: Hello, thank you for your question and my apologies for the delayed response. Product #12287 includes a single adapter. So if the first initial pair is needed, the order would need to be for a quantity of two. Thank you again for reaching out to us and I hope this helps!
    1. The earlier models would not work if the circuit went through a breaker box to the other unit OR if one was connected to a power strip like a surge supressor. DO these units work over all the wiring that comes off one mains transformer (input from the power company)? 2. Is it possible to get 100/1000 speeds in real world use or are those just pipe dreams?
    Ed W on Jan 7, 2017
    BEST ANSWER: I was getting about 20 MB/s. But they would lose connectivity way too often. I'd have to manually resync them. Gave up trying.
    Does it block the other plug at the receptacle? Or would I still have 2 fully functioning plugs?
    Aleksandar B on Jul 26, 2017
    BEST ANSWER: To answer your question, Yes & No. The Powerline Adapter AC Pass-Through outlet will accommodate both a two and three prong plug. The open electrical outlet will accommodate a two prong plug no problem with the Powerline Adapter plug into the other outlet. The problem I have encountered is not all three prong plugs will squeeze past the adapter and fully/safely recess into the open outlet.
    Has anybody's adapters cut out on them? The lights seem to work on my adapters, but, I've tried a million times to pair them and get the network established. I haven't had it work for me in months at this point.
    A shopper on Apr 1, 2018
    BEST ANSWER: All I have not had that issue. I thought I was having an issue with poor speed but found that I was still hooking to my network through wi-fi-. I turned the wifi off on my end device and it began routing through the cat5. Have not had the issue since.
    Does this have POE? I have a POE wireless AC router I'd like to hook up to this and was hoping it would provide power over ethernet to the device.
    A shopper on Jul 13, 2017
    BEST ANSWER: No it does not. You would need a separate power injector between this device and the device that needs the power. That said the power injector must meet the need of the device you intend to power. POE from the router ends at the first module.
    Can I put 4 of these together to make a network (ie all talk to everyone, peer to peer)?
    Ross P on Jan 2, 2017
    BEST ANSWER: AV2 Homeplug adapters create a mesh capable of connecting more than one Powerline adapter together. A router/switch is required on at least one end to enable IP protocol traffic. When using multiple adapters, depending on house conditions, they can create better or more reliable connectivity to the 'Gateway' adapter (The plug that is connected to the Router/Switch). Based on AV2 Homeplug standards, up to 8 can be meshed together. This depends on brand and environment needs. Please lookup more information on AV2 Homeplug standards for more information.
    Will this work with Verizon midi card?
    A shopper on Jan 6, 2018
    BEST ANSWER: My best answer is! If your device mini card can be inserted to as modem as a service then if it can outputs to a Ethernet card to this adapter with AC Pass. Then yes!

    Both of my adapters with ac pass works great I’m average 300mbits a sec. please you must use two if you want to transfer Ethernet to ac the ac to Ethernet without knocking down walls. This is an awesome device!!!!!
    The powerline utility doesn't seem to work under win10 64 bit ? I see its icon in the taskbar (bottom right) but nothing happens when I click on it. ?
    Reinier d on Aug 3, 2017
    BEST ANSWER: I'm using it under 64-bit Windows 10 and the utility works fine for me. It may be that the utility is open on another Windows desktop (ctrl-windows-left/right to check). Regardless, you don't actually need the utility for the adapter to function. There are some settings you can tweak, but my experience is that it's mostly informational.
    It has started turning off randomly when the computer is shut down? Anyone else experienced this and know how to solve it?
    Raphael A on Mar 3, 2017
    BEST ANSWER: Sorry to hear of the issue you have experienced with this item. As a previous answer has mentioned, try re-setting/re-pairing the adapters to see if the issue still occurs. I would also recommend for testing purposes to try them on different power outlets to see if it still occurs.

    Should you require additional assistance, do not hesitate to reach out to our technical support team.
    Are these known to work with other brands, ie Netgear? Thanks!
    Kao V on Nov 28, 2016
    BEST ANSWER: These adapters meet the AV2 Homeplug standard. And while yes it supports other brands, performance can be degraded if the specific brand uses unstandard features. These MP adapters worked well with some TP-Link and TrendNET Adapters I already have in the house.
    Has anyone used these in an apartment building?
    Dakota G on Jul 13, 2017
    BEST ANSWER: No bit have used it at home. Shoudl still work

    Powerline Gets The Job Done
    I bought this adapter to extend my network so that I could provide power and network access to an IP camera without having to make an Ethernet run or create a ton of Wi-Fi traffic. It works and gets the job done even if the speeds I'm getting are on the order of 50 Mbps. Fortunately, for my application, I don't need the full 500 Mbps that the specification enables.

    PROS: Cost-effective way to easily extend your physical (Ethernet) network taking advantage of the wires already in your walls.

    CONS: Even with 500 Mbps adapters, available speed and throughput will depend upon the quality of wiring and distance between adapters - in effect, your experience may vary.

    Ok but...
    Maybe I was never intended to get decent Internet service in my detached garage. The first attempt was just picking up WiFi from the house. Very intermittent and slow when it did work. Different cards and antennae didn't help. So, on to a WiFi repeater. It went in the house at the wall closest to the garage. Sort of an improvement but then the weak link was from the router to the repeater so it's still intermittent and slow. Couldn't find a place to put the repeater that worked well on both ends at once.

    Time to try something completely different. The Monoprice Ethernet over Power (12287) seemed liked a better way to do it. The max advertised range is 300 meters with the note that it works best up to 100 meters. So, even allowing that the power lines might be 3 times longer than the actual path it was still under half the 100 meters end to end. Found it from Monoprice on Ebay with free shipping.

    When I first plugged it all together and got all green lights life looked good. But then trying to get the Powerline Utility software to work brought reality back. Neither end could see the other. The link was there and the router was assigning an IP address but there was no real connectivity.

    After considerable fiddling the remote end started showing up now and then. That was good enough to get it logged in. Now I've got a red light on the link status (PLC) LED. That means 20 MBPS. So, I fiddled some more, moving the garage end to a plug closer to where the power enters. Still a red light but the link seems to be staying up. Running a speed test instead of the 15+MBPS downlink speed I see at the router end I've got a reliable 5 MBPS at the garage. Not great but usable.

    3 Stars seems like the most descriptive rating. You may do better, or worse. My case seems like the very thing this box was designed for but the performance is right on the edge. There's nothing unusual about the house or the noise environment. If it hangs on a few weeks, I'll keep it.

    PROS: Basic installation is easy as long as you have a solid path.

    CONS: 300 meters????? 100 meters??? It seems that if you're too far for WiFi, this may not do the job either.

    Works great!
    These Powerline Ethernet over Power adapters are working great for me. They have allowed me to move my wireless access point to a more centralized location in my home as I hoped and the speed is great.

    PROS: Once set up they work great.

    CONS: Set up can be a little tricky. Support staff knew little about the product so were no help. Follow the directions precisely and they will work great.

    Quick and Easy
    I bought three of these, and they worked perfectly out of the box. Set-up time was negligible, and now I've got 150+Mbps throughout my house. A big improvement over wireless!

    Excellent...so far....
    I bought these to send internet to my master room and avoid drilling and routing wires. It was fairly easy to set up ans has been working flawlessly. I like the power saving feature because it saves energy but turns up quick as soon as I turn on the streamer. Planning to buy more and hoping to see this item with wifi extender built in

    Works really well.
    Works really well. Saved me lots of time. The receptacle came in handy. Plug and play. Easy setup. You need to buy 2 for this to work.

    Easy way to extend your wired network
    This technology has come a long way. I originally purchased a 10Mb pair many years ago and they never worked despite all of the outlets being in the same electrical panel.  

    This pair work MUCH better and are very easy to set up and use.  These worked very well in the scenario listed above - outlets in the same electrical panel.

    I tried to use these to provide network service to a barn that is on the same main power feed from the power company but in a different electrical box and could not get them to pair back up again. This is beyond what the manual says is possible and does not diminish the quality or use of this product. Just wanted to list this ad it is not mentioned in other reviews.

    Flexible Internet Options on a Budget
    Got a great price from Monoprice for a product that has given me options & mobility. Without a lot of expensive re-wiring I'm now connected to the Internet throughout the house and office. Great product.
