Hub One dropping connection

[#1]

After years of stable ADSL I moved to FTTC with it going live on the 19th. The supplied Hub One switched over from ADSL to fibre (40 / 2) without a problem and all seemed well until I noticed this morning that the connection with my Synology DS215J had dropped. Checking the Hub's event log showed that there had been a succession of PPPoE drops since the 20th (see below). Is this likely to indicate a faulty router or is there a line fault?

We're seeing a few disconnections, which seem to tally up with the timestamps in your logs:

 There aren't a lot of disconnections though, are you seeing more happen that shown there?

No further drops Chris. The drop last Monday was, I suspect, when I swapped out the old TP-Link for the Hub 1. Before that connections seemed to be rock solid, certainly I never noticed any issues and the router seemed to be up for ever. The Hub 1 seems to be stable at the moment having stayed up for over a day. I will monitor it over the next few days to see if it has indeed settled down.

Thanks, let us know how it goes and we can check for  disconnections if they come back again.

Problem is still here. Hub 1 lost connection just now:

and then came back with:

(604331.500000) PPPoE is up -​ Down Rate=17923Kbps, Up Rate=1999Kbps; SNR Margin Down=6.2dB, Up=15.0dB

I think that is the second drop today and there was one on Tuesday morning.

I ran a quiet line test this morning and all appeared well, so line noise shouldn't be causing the problem.
