Check the hardware connections, and make sure the LEDs are behaving as
expected. See
Section 1.6 on page 29
.
3
Make sure your Internet browser does not block pop-up windows and has
JavaScripts and Java enabled. See
Appendix C on page 359
.

If it is possible to log in from another interface, check the service control settings
for HTTP and HTTPS (
Security Settings > Service Control
).

Reset the device to its factory defaults, and try to access the ZyXEL Device with
the default IP address. See
Section 1.8 on page 32
.

If the problem continues, contact the network administrator or vendor, or try one
of the advanced suggestions.
Advanced Suggestions
• Make sure you have logged out of any earlier management sessions using the
same user account even if they were through a different interface or using a
different browser.
• Try to access the ZyXEL Device using another service, such as Telnet. If you can
access the ZyXEL Device, check the remote management settings and firewall
rules to find out why the ZyXEL Device does not respond to HTTP.
• If your computer is connected to the
WAN
port or is connected wirelessly, use a
computer that is connected to an
ETHERNET
port.\
I can see the
Login
screen, but I cannot log in to the ZyXEL Device.
1
Make sure you have entered the password correctly. The default admin password
is
1234

You cannot log in to the web configurator while someone is using Telnet to access
the ZyXEL Device. Log out of the ZyXEL Device in the other session, or ask the
person who is logged in to log out.
3
Turn the ZyXEL Device off and on.

If this does not work, you have to reset the device to its factory defaults. See
Section 34.1 on page 311
