Test Powerline - advice



I’m testing Powerline, type PH3 Tenda (I’ve tried others from other vendors) with bad results,
I have to put GS IP Phones at a customer (there is no WIFI and LAN network in some rooms), and I ask those who have experience of me to kindly report valid products.



I have used Trendnet and TP-link with some success. In fact, my GXV3275 at the house is on a TP-link now, but there are some things to consider -

  1. The age of my house is rather new and therefore the wiring may be more suited for powerline.
  2. I have the wired powerline adapter (Ethernet) as close as possible to the other remote and on what I believe to be the same circuit and although I have not verified it, it does work for my needs but certainly not at the advertised speeds that all the manufacturers claim.

I think most are based upon the same chipsets and likely similar in design depending upon the age of the device and how the chipsets evolve. I had a Tenda as well, but the two I mentioned seem to be a little better, but in full disclosure, I moved the wired one to a different location so that may explain why my current results are better.


In my honest opinion Damiano, and for the audience.

One of the many problems with any ethernet over power device, is power surges that reset the link between the slave and master which means they have to be paired again at every surge event that occurs.

Consider using a WiFi device that provides power out of its ethernet port - like that of some of the Mikrotik products with passive POE out - just need the right power supply.


I’ve used a few different TPLink models for some work from home users on Panasonic Remote sets. Some they worked and never had a support call about them.

Other users they didn’t work at all, (older homes/wiring).

Some users I had support calls to re-sync them a few times.

I would not use them again myself… They are good for a hobyist or tech guy that doesn’t mind fixing them and can’t run a wire for whatever reason and/or doesn’t want wifi interference.


thanks to all,

I am not in favor of the Powerline, in the professional field I share the fact that they are not good.

I had a particular problem that just made me waste time, basically I took a Tenda P200 and it never worked, then I got a Tenda PH3, same result.

Yet on Amazon Italy the Tenda PH3 is the best-selling powerline, so I say “is it possible that only for me it doesn’t work?”

I discovered the problem, even if very strange, practically the 2 powerline devices in all cases were paired correctly, but if I connect the LAN of my laptop the data network is completely absent. So at some point I connected some IP phones and to my amazement I found that they worked perfectly, zero latency, I got another PC and it works perfectly. Low ping and low jitter.

In practice I found that only the LAN card of my laptop does not work with the powerline, I highlight that the same network card (which I use every day) if I connect it directly to the switch works, so I never thought that was the problem.
It is as if the network card of my laptop is incompatible with the Powerline.

I reported this story of mine through Ticket a Tenda, I avoid commenting on their answer, professional zero.

I point out that I tried the powerline in my laboratory, a very old house with an older electrical system.
I wanted to tell you this story, hoping it will be useful to you, as well as considering whether the environment where you put the powerline is an old or new house, and if the electrical system is recent or not, also consider that there could be an incompatibility between the user’s network card and the powerline you are installing.

Thanks again to everyone and good luck.


Powerline devices are extremely sensitive to the wiring conditions and if they need to cross panels, then they may not work at all or with such a diminished speed to be worthless.

Unlike the others, I have used Cisco, Tenda, TP-Link and Trendnet and I have never lost the programming in a single one and in my older home in S. Texas I had 5 devices installed and they all made it through a number of hurricanes with the associated power fluctuations and outages of same without a hitch.

May have something to do with the power, but I find it strange that a loss of settings, which are written to the NVM types of today, would incur a loss of programming without an overall corruption/damage to the device rendering it permanently useless unless the device has a battery needed to hold the cell charges has gone dead. I am not saying that what the others are reporting is not true, only that my experience with same is not that.

Unlike the others, I also prefer powerline over WiFi repeaters where I can get away with it. I will not use the repeaters. However, I concede that perhaps some of those today are likely better than the ones I tested earlier, but regardless, they are still repeaters with the same potentials shortfalls of any WiFi except magnified.


In my opinion, it’s better to use coax and MoCA devices to bridge a network rather than powerline style devices. If you have any coax in your house or building, use MoCA and wireless access points.


I too agree with the thought. I have used moca a number of times, but I assumed it to not be available in the discussion given the thread of powerline. However, my assumption may not be correct, so a good point.


i don’t know exactly what this MoCA is, but if i have to lay a coaxial cable, at that point i lay an ethernet cable, or am i missing something?


It’s a question of what you might have available, not what you may have to run. If you happen to have cableTV, then perhaps it’s close enough that you can use a moca device.


As far as I know, almost every house has coaxial cable run inside for TV whether it be in the wall or the cable company stapled it outside the walls at some point. Here is a link to MoCA adapters that I have used. These have 2.5G Ethernet ports now.
