Hi,
I have couple of PL7411-2nD worked well for 1 years and now is not working at least not bridging pwrline with ethernet
Power line looks like create the link with PLC

       connection-to-plc: ok
         tx-flow-control: no

           plc-line-freq: 50Hz
       plc-zero-crossing: detected
                plc-role: central-coordinator

                          E:0E phy-tx-rate:52Mbps phy-rx-rate:32Mbps

Phew. Not just me with the same issue. Spent the last 6 hours trying to my two PL7411-2nD talking to one another after upgrading to RouterOS 6.48. Finally got them working by downgrading to the long term release, 6.46.8.

i have some new units and upgraded them to 6.48 and couldnt get them to link, the running status would never show, even though everything looked ok,
I followed your tip and downgraded to Stable 6.46.8 and it now works. there is definitely something wrong in the new 6.48 for the PLC units.

Thank you it works also for me. downgrade to long term

I had the same issue and I opened a support ticket with them around the end of last year. In Ticket SUP-37469 I was told on 2020-12-29 that it will be fixed with the next stable release. I now saw, that it was fixed with 6.48.1 (2021-Feb-03) The changelog says:

*) interface - fixed pwr-line interface linking (introduced in v6.48);

I will test this now. → It works.

Thanks for the notice. My two also working on stable 6.48.1.
