Hi,
Hope you can help, since upgrading from standard DSL to VDSL Fibre at the back end of last year the connection has being dropping out quite regularly.
I was using the supplied talktalk superrouter and also had a lend of another one. I've now changed this for a Fritzbox 3490 but had the same issue with all three.
The issue seems to be around two things, 1. DHCPv4 no answer on discover and 2. No DSL Sync.
I've copied the log from the modem/router this morning - this is below.
I have had line issues previosuly and suspect that this is the case again as I have also randomly had no line signal on my phone - although I dont seem to get any noise when its working.
Hope you can help as getting rather frustrated with it.
For example this is the log from today;
