    • Administration->Firmware Upgrade
    • Select the firmware file and "reset to defaults" from the drop-down menu, then click Upgrade
  • ...or use the reset to default settings option:
    • Administration->Factory Defaults

[edit] Command Line Interpreter (CLI) Reset

Telnet (or SSH, if enabled) to the device and see Erasing NVRAM, as this is build-dependent.

[edit] Reset Button

With the firmware is running normally, hold the reset button until the lights flash (10-20 seconds).

[edit] Reset notes

In February 2015 Kong stated a reset is required for certain upgrades, such as certain wireless driver updates]. While not usually necessary, reset and manual configuration should be performed if any issues are encountered, and only report issues after this is done. Do NOT restore an nvram backup (NVRAMBAK) from previous builds in these cases, as it will undo the reset.
