Table 36   Troubleshooting the Password

I cannot 

access the 

ZyXEL Device.

The default password is “1234”. The Password field is case-sensitive. Make sure that 

you enter the correct password using the proper case.
If you have changed the password and have now forgotten it, you will need to upload 

the default configuration file (Refer to
