You could argue it. You would be wrong. Switching operations are an integral component of predicting lifespan of "switchgear." Switchgear refers to products like circuit breakers, switches and switch fuse units.

Is the impact to lifespan significant? It depends on the device. Most likely, with something like a WiFi router, the device's technology will be out-of-date before switching operations kill it. Regardless, the timer/on-off cycle is a kluge in an attempt to fix a more significant underlying issue - an obviously junk router.
