The parameters are configured as follows: 9600,8,n,1

2. Restart the router , in the process of restarting, HyperTerminal displays "######", The notebook presses the Ctrl+fn+break key, the desktop computer presses the Ctrl+break key. In addition, some notebooks do not have a break key, and I have to take another desktop USB keyboard.

3, the router in the boot process, into the Rommon state.

4, modify the Register value, enter the command: Confreg 0x2142.

Rommon 1 > Confreg 0x2142//Change the configuration register value to 0x2142

Rommon 2 > Reset//Restart router

5. During the restart , the device asks whether to initialize the configuration and enter No.

Would to enter the initial configuration dialog? [Yes/no]:no

Press RETURN to get started!

6. The Router skips Initialize Configuration start mode, enter configuration mode,

Then you can change the password.

7, test the new password.

8. Modify the value of the register: Use the command config-register 0x2102

9. Use the command Show version to view the value of the register.
