Hi Ruairi, I wasnt aware it was sensitive to electrical noise etc. Other than replacing the master socket, nothing else electrical related changed around it when the dropouts started.
Im fairly sure that PPPoE drops are due to it losing sync - it happens every time and I can observe that through the logs/"show controller VDSL 0" etc. Might be about time to swap it out for something else. Ive been meaning to throw a Juniper box in, maybe this is just the motivation I need. :-) On Mon, 16 May 2022 at 14:44, Ruairi Carroll <ruairi.carr...@gmail.com> wrote: > > > On Sun, 15 May 2022 at 13:26, Tom Storey <t...@snnap.net> wrote: > >> Hey James, >> >> Cheers, will take a look through it to see if theres anything I can use. >> >> I'll try enabling the training log at some point.
