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 placed one in the living room at the router and the other in the inner bedroom, with another bedroom, kitchen, toilet, and hallway in between...
This distance entails a different switch/fuse phase in the panel... I think these switches only cut the phase... Neutral and ground should be common... Also, if I'm not mistaken, the powerline with a socket 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 ground might be SISO, hence their usually lower communication speeds...
So, from the 100 Mbps that I have given it, it has brought me 50-70 Mbps without instability or interruptions so far... I also added an access point on top, and it's okay with the wireless part... Because I was mainly interested in the 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 you put it in play a very important role... The rule is exclusively and only directly into the socket, and then you can plug in whatever else you want after the powerline... It didn't connect at all to a power strip, in others it happened to work with 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 placed 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 socket T 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 heat up slightly... But generally, I would say it's okay....
-Update after a few days... They didn't disconnect, nor did they disturb my internet browsing in any way... But they started giving me somewhat lower speeds than I had 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 that it was trying 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 does some error correction, and that's why it raises the ping, I don't know...
This hasn't bothered me since then either, and the ping has dropped or rises slightly at intervals on the powerline network part... But it doesn't seem to disturb...
Also, during a quick power outage, it seemed to freeze 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...
Generally, as I said, it's okay... Not something great like the cable, but okay, it did the job somewhat...
From 10 that I was getting with a repeater/extender inside 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 5GHz band (instead of 2.4 now) that will require higher speeds...
Once when I was using the network through the powerline, it interrupted the signal of the TV that 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..
Even though I never had stable speeds...
I had given it a 100Mbps port in the living room where the router is, and inside the second bedroom quite a distance of about 20-30 meters straight, so 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 achieves... I mean having a wired network everywhere...
After 1.5 years, it has come to give me 40 when it feels like it and 25-30 normally... In both directions up/down... I have made some changes to the sockets like adding smart plugs & ups always after the PLCs so that they don't affect them.... But even without those devices on the line, it doesn't improve again like before....
I paired 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 further, I'll see what to do with them.... That is, more thorough research...
Until then, for higher speed, I'll put a 5G extender somewhere in the hallway....
And generally, I'll have 100 networks as the situation has turned out...
I might become a bit annoying, but guys, really, if you can run a cable, please do it...
These devices are really, as it seems, just an emergency solution....
