Searched hi and lo but found no help. Half a dozen BT visits and Draytek support but still getting random drops mostly overnight. No-one can see any line issues and done the usual reducing of MTU and boosting SNR to no avail. BT now saying its a SHINE issue which is just not possible given the timings. Last night I unplugged all ethernet connections and switched off wifi on 2860. The BQM is attached:
My Broadband Ping
Graph up to 2230 is pretty typical with one drop around 2130. Between then and 1000hrs the following day is when the Router was isolated from the LAN but again showed pretty typical "spikes" and "drops". Can anything be deduced of value from this kind of behaviour please......losing hope!!
(please ignore left and right of graphs as I was trying different firmware loads!!)
