Ahhhh, this is kind of a trick question. Many times power cycling is hail marry of technical support. Internet is slow, power cycle. Cant get on..power cycle. Weak wireless signal, power cycle. Its such a easy fix for so many different problems, some people come to the conclusion power cycling is needed on a normal basis. It is not. Atleast not once a day/week/and even month some people do it. Many times their is a underlying problem that isn't being addressed. Signal levels causing T3 errors to modem, power fluxation to the equipment, IP conflicts, virus on a computer on the network flooding the router with technical gibberish that causes it to crash. All kinds of stuff.
