• Check that the cable's connector is firmly inserted in the LAN terminal of the device.
• Check that the cable is firmly inserted into a LAN port for a PC or a network device
such as a hub.
• Check that the LAN cable is a Category 5 cable.
• Check that the LAN cable is a cross-over cable when connecting the device to a PC
directly.

be the same.
(Example)
When the IP address is "192.168.150.2" and the subnet mask is "255.255.255.0" for
