Fibre connected, but nothing workis

A couple of times over the last few days I have noticed that my internet connection drops out. If I log in the SR102 it reports the same WAN IP and connection as being up, but there is no DNS, and I can't ping the default DNS servers, etc.

If I click the disconnect and then connect buttons, connectivity is restored for say 24-32 hours before it might go wonky again.

anyone else seeing dodgy behaviour? When I was using my HG612 and Vigor 2820 I never saw these total failures, with both units reporting uptimes of 300+days. To make matters worse, it knocks out my SureSignal box so then I have no Vodafone mobile data (obviously wifi isn't working....)

Tried using different DNS servers, though the fact an IP will not ping suggests it is not that.

SR102 stable as any router I've ever had here.

It has just done it again.... noticed the connection was very slow, so I tried a ping.

The ping went back to 12ms for a few pings after I performed the disconnect/reconnect, but then went high again (300+ms).

Guess I am going to have a try their support line. Or I could swap back to using my HG612 and see if that suffers, but then I'm not in a supportable "condition".

You could swap back to the BT OR modem and your router if you have the correct sky log in credentials needed, for process of elimination purposes, but don't be rebooting the modem frequently or DLM will clobber the connection

If foolwing the change to the BTOR modem everything works properly, i would leave it like that if you ever get an issue just swap back again before you ring em

could this be linked to ???

The fine for a short while after a restart is the sort of thing that suggests something is doing an awful lot across your connection e.g. P2P software

Transmission was running on rpi, but there were only a few (old) torrents - such as old rpi images, so I doubt it was generating a lot of traffic, but possible.

I have now successfully flashed the latest firmware into my HG612, so I have switched back to that. Haven't seen a similar issue in the last few days, so fingers crossed.
