I was having problems with my cable internet periodically dropping out for a few minutes at a time, it took them two or three tries, and every time the support guy came out they were very careful to tell me that "your neighbors grow lights may cause that when they switch on at some particular time every night". So I guess they do put out quite a bit of RF noise ;)

Think it was a firmware bug in the modem, because the modem never realized it was offline or showed a connectivity disruption on the street. Luckily it dropped off one time while I was on the phone with a tech. They were using a new Charter Spectrum branded modem and as soon as they swapped to an Arris it stopped happening.
