During the firmware upgrade process for Gargoyle routers, a temporary loss of network connectivity is expected. This interruption occurs as the device overwrites its existing operating system with the new version and subsequently reboots. The duration of this disconnect typically ranges from a few seconds to several minutes, depending on the hardware and the size of the firmware image. Such disconnection is a normal part of the flashing process and should not be cause for immediate alarm.
The brief network outage is a necessary step to ensure the integrity of the upgrade. It allows the router to properly load the new firmware without interference from ongoing network traffic. Failure to allow for this interruption could potentially corrupt the firmware during installation, rendering the device unusable. Historical issues with firmware flashing in various embedded systems highlight the importance of this controlled disconnection.
