If a line is dropping during the day, and maybe just Monday to Friday, then it's probably not going to be an upstream problem. This could be caused by interference of bad wing on site. Check things like the phone line and extensions. Put the router in master socket and to unplug all other phones. Maybe change filter.
==Examples of things that are not a fault==
[[File:Cqm-normal.png]] A normal graph shows no packet loss (no red at the top) and little of no change in latency when downloading or uploading at low rates. Compare to congestion graph above.
[[File:Cqm-sawtooth.png]] This graph has a saw tooth latency pattern. This can sometimes be just in green (peak) latency or in blue (minimum) latency or some combination of the two. It can be regular like this or change frequency. This is just the way this specific make of router responds to LCP echos and is not actually affecting traffic.
