Factory Default Reset button
There are two ways to reset the router's factory defaults:
1. Use
the Factory Defaults function on System Tools -> Factory Defaults page
in the router's Web-based Utility.
2. Use the Factory Default Reset button: First, turn off the router's power. Second,
press the default reset button, then turn on the router's power, and hold the
reset button until the M1 and M2 LED flash simultaneously (about 3 seconds).
At last, release the reset button and wait for the router to reboot.
