Not an ADSL Fault. This latency and loss was caused by a fault Netgear switch on the LAN side of a Vigor router! The switch had failed to the point where it wouldn't talk gigabit but would talk 100M unreliably. Guess it was maxing router CPU perhaps. It's unknown whathow wasthis exactlyaffected causingthe thisVigor, but perhaps the switch was faulty enough to upset the Vigor causing it to delaying or not replying to the LCP echos. In this case unplugging the LAN side of the router would show a normal looking graph, indicating the fault is somehow caused by something on the LAN.
