Do I really need to reset the router to factory defaults when upgrading firmware?

Every time there is a firmware upgrade, it says after the installation to reset the router to factory defaults. Is that really necessary?

Most of the time, the answer is "no". There are sometimes changes in newer firmware that are not compatible with previous versions requiring a reset. If you upgrade the firmware and everything works, no reset required. If you upgrade the firmware and have problems, it is advised to reset to factory defaults before seeking help with an issue. To assist with getting your router back to the same configuration before resetting, create screenshots of your settings.
