Yes, John, I've done everything possible and then some. No change.
Five BT engineers, all say internal cabling is fine, two say there's an underground copper line fault and one found a bad joint at the pole where our line rises and the down line is attached. Master socket replaced and BT cable to downline; cable to first floor extension socket and the socket tested by BT. Filters replaced.
The history goes back to Dec 15 when all of the properties nearby lost broadband, one for 3 days (BT notified him of it by phone so there must have been something of which BT was aware). Everyone came back but we (i.e. just this line, others all OK) started to have serious problems in Jan 16. All seemed well in Aug & Sept (d/l speed c.20, stable connection) and then it started again; we're now (TG582n) getting spells of outages every 50 to 90 seconds.
I've now changed the router (old Netgear DG834Gv2) but that is having outages regularly and it doesn't provide the error stats that the PN one does. (Wifi speed is poor, too.)
Current data:-
Uptime: 30m.
Sync 17.635 (down 1.5 on yesterday when first connected via the 834), SNR 6 (up 3), down attn still 16. D/l speed (Ookla): 15.36 (16.19).
So, with a different router, I am already seeing outages and falling sync & d/l speeds.
