While I 100% support power cycling as a troubleshooting step, it doesn't answer the question as to why something went wrong. For fixing the air conditioning in my car once in a blue moon, fine. For figuring out why my internet drops out once per day, it's only a triage step.
My philosophy is that the first time something funky and unexplainable happens, power cycle and don't spend a bunch of time on it. But keep and eye out for the same thing and if it happens again, then investigate.
Using it to solve a daily problem is a terrible idea, if you have any control over the system.
