I feel the need to ask this as well.
I've been in IT for nearly 30 years and never reboot anything unless there's a specific reason (such as firmware updates or patches). Even with a need for a reboot, it is done during approved, scheduled maintenance windows.
To this day, I cannot understand one's need to reboot a router on a weekly basis. If it is functioning normally, leave it be. If there is something so fundamentally wrong with the device that it requires said reboot, then the setup is wrong and needs to be reconfigured, or the device physically needs to be replaced.
