PROBLEM
CORRECTIVE ACTION
I cannot
access the
ZyXEL Device.
The default user password is “user” and admin 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. This restores all of the factory defaults including the
password.
I cannot
access the
web
configurator.
Make sure there is not a telnet session running.
Use the ZyXEL Device’s WAN IP address when configuring from the WAN. Refer to
the instructions on checking your WAN connection.
Use the ZyXEL Device’s LAN IP address when configuring from the LAN. Refer to for
instructions on checking your LAN connection.
Check that you have enabled web service access. If you have configured a secured
client IP address, your computer’s IP address must match it. Refer to the chapter on
remote management for details.
Your computer’s and the ZyXEL Device’s IP addresses must be on the same subnet
for LAN access.
If you changed the ZyXEL Device’s LAN IP address, then enter the new one as the
