Make sure your clients are in the same IP subnet in the LAN/VLAN/DMZ networks behind the Zyxel
Device. Information from clients that are in different IP subnets in the LAN/VLAN/DMZ networks might not
be collected correctly.
To report on clients that are wrongly identified, go to Monitor > Network Status > Device Insight >
Feedback.
I cannot remove a client in Monitor > Device Insight.
Clients that are blocked cannot be removed. Please make sure to unblock the client you want to
remove first.

29.1 Resetting the Zyxel Device

If you cannot access the Zyxel Device by any method, try restarting it by turning the power off and then
on again. If you still cannot access the Zyxel Device by any method or you forget the administrator
password(s), you can reset the Zyxel Device to its factory-default settings. Any configuration files that
you saved on the Zyxel Device should still be available afterwards.
Use the following procedure to reset the Zyxel Device to its factory-default settings. This overwrites the
settings in the startup-config.conf file with the settings in the system-default.conf file.
Note: This procedure removes the current configuration.
Make sure the PWR/SYS LED is on and not blinking.

Press the RESET button and hold it until the PWR/SYS LED begins to blink. (This usually takes about five
2
seconds.)

You should be able to access the Zyxel Device using the default settings.
