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.
