How do I reset the MiFi 4620L back to factory settings?
The master reset button is in a small hole located on the bottom of the device, underneath the
battery cover. This button returns the device to factory settings, including re-setting the network
name (SSID) and network key (Wi-Fi passkey) to those printed on the sticker axed to the back of
the device. To reset the device, follow these steps.
➊ Place one end of an unfolded paper clip into the master reset button hole.
➋ Press the paper clip on the button until the LED blinks green one full blink and then a very
brief blink (about ve seconds).
