It could be helpful to add a small note to the manual https://download.peplink.com/manual/peplink_balance_and_mediafast_firmware_manual_fw8.0.0.pdf page 228 -
There is a dual function to the reset button.
Hold for 5-10 seconds for admin password reset (green status light starts blinking)
Hold longer than 10 seconds for factory reset (green status light turns red, maybe?)
I was confused by the behavior when I tried it until I searched this forum. When the green light started blinking after many seconds, I thought that was doing the factory reset. It was actually only telling me that the admin password had been reset. I continued to wait for several minutes while nothing was happening thinking the factory reset had been initiated, which it had not. I didn’t want to risk interrupting it.
The manual currently says:
"Appendix A. Restoration of Factory Defaults
To restore the factory default settings on a Peplink Balance unit, perform the following:
For Balance models with a reset button:
- Locate the reset button on the Peplink Balance unit.
- With a paperclip, press and keep the reset button pressed for at least 10
seconds, until the unit reboots itself."
