Advanced Suggestions
• 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 a ETHERNET port.
I can see the Login screen, but I cannot log in to the ZyXEL Device.

user name is admin. These fields are case-sensitive, so make sure [Caps Lock] is

the ZyXEL Device. Log out of the ZyXEL Device in the other session, or ask the
person who is logged in to log out.
