| Feb 13, 2018 at 9:29 | comment | added | EvilDr | @harrymc The router, switch and adapters all have the latest firmware. | |
| Feb 13, 2018 at 9:28 | comment | added | EvilDr | @Tim_Stewart only about 10m. If it was noise, why wouldn't the problem occur now, when the adapters are connected direct to the router? That's the part that confuses me | |
| Feb 12, 2018 at 14:41 | comment | added | harrymc | You are not using the latest firmware for the switch : Yours is 2.0.1.26 while the latest is 2.0.1.40 (download link). Maybe a later version will better deal with your powerline adapters. | |

| Feb 12, 2018 at 13:28 | comment | added | EvilDr | @Burgi Annoyingly, there appears to be no interface option to view the logs. I also notice that the router itself claims it cannot connect to the "registration page", which I believe is an external web page. I've added a screengrab of the main page. Perhaps somebody will notice something amiss... | |
| Feb 12, 2018 at 13:13 | comment | added | EvilDr | @JourneymanGeek The make and model are in the OP, if that helps | |
| Feb 12, 2018 at 13:04 | comment | added | Journeyman Geek♦ | Powerline issues won't take out the network. Just that segment would go down, and you can tell from the lights. Hmm. @EvilDr what adaptors? I might have a handy tool that works with more common flavours of homeplug which might be useful | |
| Feb 12, 2018 at 12:41 | comment | added | harrymc | Did you check how reliable is the power supply of the building? Fluctuations might cause funny effects on the network to which the switch may be more vulnerable than the router, especially at the stage where the powerline introduces itself into the network or the switch is booting and discovering the network. Maybe you should try other powerline adapters. | |
| Feb 12, 2018 at 12:34 | comment | added | Burgi | You mentioned your switch is managed. Are you able to pull any logs from it? | |
| Feb 12, 2018 at 12:23 | comment | added | Journeyman Geek♦ | as a powerline user - they're mostly transparent to your system. And that's mostly the topology I use, so... that's strange. almost feels like you created a routing loop somehow, but that shouldn't happen. | |
| Feb 12, 2018 at 12:14 | comment | added | djsmiley2kStaysInside | Well that mean they are just layer two, the only other thing I can come up with is a bug in either the switch, or the Powerline adaptors that caused the mac-address table of the switch to believe that all connected interfaces were on whichever port the powerline adapters were connected to. This is partal;ly while you wouldn't normally use something like powerline in a business environment. | |
| Feb 12, 2018 at 12:11 | comment | added | EvilDr | Interesting question. This happened three times, which forced me to reconfigure as per the final diagram. The adapters do not appear to have any interface for configuration. They have no IP address (at least according to the router); instead I see the IP of the device in the second room that connects via them - almost as if they are transparent on the network map. | |
| Feb 12, 2018 at 12:07 | comment | added | djsmiley2kStaysInside | Did this happen multiple times? (It seems it may of due to the listed 'one of these happened'). If the Powerline adaptors are level 3 devices (i.e they have an IP) are you accidentally setting them up as a gateway or dhcp server when you haven't meant to? | |
