How to Change Administrator Password

Introduction
To avoid someone can easily login the router and change configuration via default administrator, default password is advised to be changed at the first time to login.
 
Prerequisites
1. a UTT Business Router (hereinafter shorted as “the Router"), such as UTT router N518W, AC750W, AC750GW, AC1220GW, ER518, ER840G and ER4240G. Firmware Version: 3.0.0 or above
2. a PC/laptop connected to the Router, either through its LAN port or wireless network
 
Configuration
1. Open a browser. Log into the Web UI of the UTT Business Router (default IP address 192.168.1.1, username: admin, password: admin).
 
2. Go to System Configuration > Management Policy > Administrator, click Edit.
 
3. Enter the new password and confirm, then click Save. (Write down the new administrator password somewhere, there is no way to login the router if password is forgotten except reset the router to default manufacture settings.)
