ZyXEL Communications IPC-3605N manual Internet connection error

Symptom	Possible Cause/Solution
Network diagnosis shows	Network connection error.
error icon	The network connection test verifies that the camera has successfully connected to
	the LAN network. When the diagnosis result shows a red exclamation mark icon, it
	means that the camera fails to connect to the LAN network. Check if the LAN
	cable is securely connected to the Ethernet port of the camera and to your
	hub/router, or check if the LAN cable is functioning normally. Also check whether

	Internet connection error.
	The Internet connection test verifies if the camera is connected to the Internet.
	When
	the diagnosis result shows a red exclamation mark, it may represent a failed
	connection to the LAN network. It could also be caused by inappropriate settings
	on your router that makes your router unable to connect to the Internet, such as the
	wrong PPPoE user name/password, or wrong WAN IP settings (when your ISP
	provides you with fixed IP address). See if the PC connected to your router can
	also access the Internet. If not, consult your ISP/ router manufacturer for correct
	Internet setting. If your router can connect to the Internet but your camera
	connected to your router cannot, check whether the IP, subnet mask and gateway is
	correctly set on your camera.

Problem using eaZy	The IP camera’s IP address is repeatedly displayed as “DHCP mode” in eaZy
Wizard	Wizard.
	This means the camera cannot obtain an IP address from DHCP Server or the IP
	address assigned to the camera is not on the same subnet as the LAN network.
	Please try to set the camera’s IP address to a static one. Note that you have to set up
	the DNS server for your camera (in the advanced network settings) if your camera
	uses a static IP address.
