Hi all!
Couple of days ago i bought a pair of PWR-LINE PRO. Install and sync - ok. But after some time (30m-1h) network connectivity between Routers(HexPOE) are lost (or huge and missing pings).
PWR-LINE PRO - in Sync state, LED is ON, Routers port are UP and 1000G FD negotiated. But no RX/TX.
So if i power off one of PWR-LINE PRO device and power on again - connectivity become OK, but for 30m-1h.. What’s gonna be ?
Thanks.
The main problem is - how to do diagnostics?
PWR-LINE Pro - has no management interfaces, no IP, etc.
You could try to re-link both of the devices.
Hold 5 – 8 seconds. A new security key is generated. This is needed to remove a PWR-LINE PRO device from an existing PWR network.
after that, re-link -
Hold 0.5 – 3 seconds. For 120 seconds will try to communicate with another PWR-LINE PRO device.
Already do this. Even more - Hold 8-15 sec and reset both devices. And than sync them - same issue.
Is there any “Powerline AV Utility” for Mikrotik ?
Those devices have no software (no OS), so this is the reason why you can’t connect to them and there is no “utility”.
Did you try to connect them to other outlets, to put them closer to each other?
i will try this later today. but if the problem in wire why LED “Sync” are ON?
i know that they have no OS, but other vendors provide utility to remote FW upgrade/diagnostic.
Are they plugged directly into the wall (not via power bars etc)??
Thru couple of 16A automatic switches and DIN attached outlets. Cable length ~50m.
Yesterday i put first PWR-LINE PRO closer to second one - without 16A auto switches and cable length - 10m . For now connection looks stable.
So my problem looks solved for now.
Automatic fuses/switches are killing powerline. Same as wireless through reinforced concrete.
Parallel cable runs help somewhat … as does a window in that concrete wall for wireless.
I think “Wago” is a root cause in my case
how can you sync 3 pwr-line Pro on the same electrical circuit
How can I sync 3+ devices PWR-LINE PRO?
I have two synchronized (1, 2). So I set both (1, 2) into sync mode, then start syncing for 3rd device. After 120 secs no changes, third device not in network. Same if I run sync with 1, 3 or 2, 3 pairs. I also tried to press sync button for 10-15 secs, and then repeat action.
Sorry for hijacking thread, but for those who use PWR-LINE PRO - do you get additional latency? I’ve never used EoP devices before.
I’ve heard stories that when using such devices you might get somewhat 30ms latency, even tho internet connectivity is rock stable. Just want to hear if it’s true.
You do get some additional latency. A pair of EoP devices means two additional ethernet switches and they mostly work in store&forward mode which means it first receives whole frame and then transmits it through another interface. At 1Gbps with full size frames (1500 bytes is 12kbits) that means 0.08ms … at 100Mbps thats almost 1ms. And speed over power line can be even lower than 100Mbps, really depends on particular installation … and in that case the store&forward delay can be even longer. I think most of devices even perform some kind of CRC checks and do retransmitting on EoP connection .. if retransmits happen, then it’s seen as additional delay.
Additionally most devices encrypt frames when sending through EoP interface and decrypt when receiving from EoP interface. Encryption/decryption delay depends on particular device, but I’d expect delay in order of 0.5ms per device.
Practical experience with EoP devices by another manufacturer: net throughput over EoP pair is around 40Mbps (half-duplex!). One PC connects to hAP (100 Mbps ethernet) directly, another one to same hAP over a pair of EoP devices. Ping from first device to hAP shows 0.35ms RTT (almost no RTT jitter) while ping from first to second device shows RTT times between 3.3 and 6 ms (considerable jitter).
According to my experience 30ms delay shows really poor EoP conditions … or trash of EoP devices used.
This is wrong, just download any Powerline Software an you can take a look to the Powerline rated, and on some devices to the spectrum.
How come, that in original manual there is, connect to power, connect ethernet and go to 192.168.88.1, but its not working…
I have, two of PWR-LINE PRO and i’m totally disappointed…There is 20-30 ms persistent delay and also i noticed some huge spikes in latency. even if EoP devices connected directly to each other.
PWR LIne is for people afraid of drills!
They make huge drill bits these days and one can always rent a bigger drill. If you have rented a jack hammer, you are my hero!!
If I owned a jack hammer, what would that make me?
Actually i have drill…I was just curious and think that Mikrotik team made some miracle and advertised devices works well, but i was wrong, no miracle at all. =)))
