Can't seem to narrow it down, but we are running a Motorola / Arris SB6141 and an Airport Extreme. Speed tests (when they work, between 9 and 10 PM, seem to go from the usual 30-60 Mbps (depending on time of day) to either server not responding or in the 0.3-5 Mbps with roughly the same ping responses regardless (always seem to be in the high 30's, as long as I can get a response). I am fairly relieved to know that it isn't just us, but at the same time, I wonder what the heck is causing it (very similar boat as you, no new equipment, nothing new to backup or storage routines, always just after 9 PM).
