So, here a very simply way to reset it, actually it's already been there ever since, you just have to be cautious on your device.
Step 1. Log-in to your SmartBro Pocket Wifi by opening your Internet Browser /Chrome/Safari/Opera/Mozilla FireFox

To reset the pocket wifi if you forgot the password of the router:
PRESS Buttons "ON" and "WPS" at the time for about 5 secs. It should reset it to Factory Settings then you can use the default password (smartbro) to log in to the dashboard and change settings again."
After done resetting your Smartbro Pocket Wifi, please set up your wifi password. Click Here
