You'd need to get a power meter and check your house hold power to see if there is any fluxuations in power and if you have any grounding problems. Find any power devices that maybe introducing power fluxuations. If you feel there is a house hold problem, then you might get a Qualified Electrician out to the home and have him run some tests on the power in the home. You might power everything in the home off while testing is happening. Large items. Try them all off and then bring them online 1 at a time and have the electrician test. Have them check grounding points as well.
Try a different power adapter for the cable modem as well.

Right...have done this already, which is where I'm trying to have the conversation -- why is a cable modem sensitive to power fluxuations when other electrical units in the house are not? i.e., TV stays on during viewing, lights don't flicker, can still listen to FM radio, etc. Shouldn't cable modems have some built-in electronics to manage this?
