Let's be honest, it's not like a network cable... But... When you want to avoid drilling, nailing, channels, and stories, it literally frees your hands...
In a single-phase supply...
I put one in the living room at the router and the other in the inner bedroom, which is separated by another bedroom, kitchen, bathroom, hallway...
This distance entails a different switch/fuse phase in the panel... I think these switches only cut the phase... Neutral and ground must be common...
Also, if I'm not mistaken, the powerline with a plug specifically must be MIMO in transmission, which means they use all 3 power wires to transmit the signal... That is, including the ground... Instead of the previous SISO technology that only used phase/neutral...
For example, bipolar ones that don't have grounding might be SISO, hence their usually lower communication speeds...
So from the 100 I've given it, it brought me 50-70 without instability or interruptions for now... I also added an access point on top and it works fine with the wireless part... Because I was mainly interested in wireless inside the room...
Not so much the connection to a computer with a cable... That comes second... Although if I need it, I can throw a cable from the switch of the access point and it's fine...
The wiring and the socket where you put it play a very important role... The rule is strictly and only directly into the socket, and then you can put whatever else you want after the powerline... It didn't connect at all to a power strip, in others it happened to work in a power strip, but not for me... And with a surge protector single socket before the powerline, it cut my speed in half, so I put the surge protector after the powerline for the protection of other devices... It won't protect the powerline, but what can we do since that's how technology is... I hope the powerline has some corresponding protection inside...
Of course, the well-known plastic T plug can also be used for connection to the socket if needed, as it doesn't seem to affect much since it communicates directly with the wires in the wall... If it can be avoided, it's better...
In general, although it had a bit of a run at the beginning, everything is going well.... That's it... What else... Maybe that they get slightly warm... But generally, I would say it's okay....
-Update after a few days... They didn't disconnect, nor did they bother my browsing on the internet in any way... But they started giving me somewhat lower speeds than I measured at the beginning when I set them up... Almost half....
The issue was somewhat resolved with plug/unplug and re-pairing... Also, it seemed to me that it takes a while to pair... The light was showing red/green as it tried to connect until it stabilized green... Maybe the distance or the hours that various devices operate with whatever that entails on the power network (noise) if you understand me...
It hasn't bothered me since then...
Not so much that I would do the same process again...
I should also mention that I noticed that at intervals it seems to raise the latency somewhat... It's not as low as when you connect directly to the main router... Maybe it's doing some error correction, and that's why it raises the ping, I don't know...
This hasn't bothered me since then, and the ping has dropped or rises a bit at intervals on the powerline network part... But it doesn't seem to disturb...
Also, in a quick power outage, it seems to have stuck and didn't work, the lights were blinking... I didn't let it see if it would recover on its own... I'll do that next time...
Anyway, it came back just by plugging and unplugging one device.
And I’ll say it again... It's not like the network cable... Just a temporary emergency solution if someone is lazy or can't easily run a cable... That's it...
In general, as I said, it's okay... Not something great like the cable, but okay, it did the job somewhat...
From 10 Mbps I was getting with a repeater/extender in the bedroom, I went to 50-70 depending on the time... For now, I'll manage like this and then we'll see...
If I ever decide to run a cable and look for newer equipment and access points with 5 GHz band (instead of 2.4 now) that will require higher speeds...
Once when I was using the network through my powerline, it interrupted the TV signal which is connected to the same socket...
And I've also noticed that if you don't use them for a while, it's like they go into save mode and give mediocre speeds, and with use, they wake up and increase speed...
That's it... The little things.. :)
In general, I have no issues... I declare myself satisfied...
If they had an app to see the speed, for example, that they communicate with each other, that would be nice.... But it's okay....
Update..
Although I never had stable speeds...
I had given it a 100 Mbps port in the living room where the router is and inside the second bedroom quite a distance, about 20-30 meters straight, very roughly measured in my mind, it brought me 30-80 when it felt like it, and I was satisfied with that distance and what it manages... I mean having a wired network everywhere...
After 1.5 years, it has come to bring me 40 when it feels like it and 25-30 normally... And in both directions up/down... I have made some changes to the sockets like adding smart plugs & ups always after the PLCs so they wouldn't affect them.... But even without those devices on the line, it doesn't improve like before....
I paired them again after unplugging but the same...
Disappointment, but what can we do....
At least the connection never drops...
And the ping is just fine....
That's it.... If the speed drops lower now, I'll see what to do with them.... I mean more thorough research...
Until then, for higher speed, I’ll put a 5G extender somewhere in the hallway....
And in general, I will have 100 networks as the situation has become...
I might become a bit annoying, but guys, really, if you can run a cable, please do it...
These devices are truly just an emergency solution as it seems....
After two years, the speed that was once 50-80 has dropped to 15-30..
I changed them and put them in another socket, but the distance from the living room to the bedroom affects them quite a bit it seems....
It may have stable ping a bit, it does give you a network port at the point you want, but let's face it, there are losses..
And I haven't changed anything in the house's electrical setup...
All my devices are after the PLCs...
Unfortunately, though, it is easily affected...
I would try the more branded Devolo ones that have a different communication protocol, g.hn I think, but I'm thinking about the money they cost and any potential losses again... These are usually recommended for three-phase... I have single-phase, so they might work a bit better.... But they cost a lot.. And again, their nature? They can't deny it... Logically, there will be losses again...
Now I had bought D-Link, then again with the same standard AV2, there were also TP-Link...
But the salvation is a.... This is what I said from the beginning.... Cable!!!
If I ever don't get bored maybe I'll pass it.... What can I say...
As if I'm going to get into the trap of spending three hundred to try plc...
I spent 50€ and whatever happened, happened...
After that, it will be cable, hammer, and nails.....
We won't go broke for a questionable result...
That's it! These devices are ONLY EXCLUSIVELY for emergency solutions...
Otherwise, c.a.l.l.e. cable....
