suggestions.
Advanced Suggestions
• Try to access the Zyxel Device using another service, such as Telnet. If you can access the Zyxel
Device, check the 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 LAN/ETHERNET port.
I can see the Login screen, but I cannot log in to the Zyxel Device.
Make sure you have entered the user name and password correctly. The default user name is admin

and the default password is 1234. This field is case-sensitive, so make sure [Caps Lock] is not on.
This can happen when you fail to log out properly from your last session. Try logging in again after 5
2
minutes.
Disconnect and re-connect the power adaptor or cord to the Zyxel Device.
