If the error persists, you might have a hardware problem and should contact NETGEAR 
technical support.

LAN or WAN Port LEDs Not On



Make sure that the Ethernet cable connections are secure at the UTM and at the hub, 

router, or workstation.

Make sure that power is turned on to the connected hub, router, or workstation.

Be sure that you are using the correct cables:

When connecting the UTM’s WAN ports to one or two devices that provide the Internet 
connections, use the cables that are supplied with the devices. These cables could be 
standard straight-through Ethernet cables or Ethernet crossover cables.

Troubleshoot the Web Management Interface



Check the Ethernet connection between the PC and the UTM as described in the 

previous section (

Make sure that your PC’s IP address is on the same subnet as the UTM. If you are using 

the recommended addressing scheme, your PC’s address should be in the range of 
192.168.1.2 to 192.168.1.254.

If your PC’s IP address is shown as 169.254.x.x:

Windows and Mac operating systems generate and assign an IP 
address if the computer cannot reach a DHCP server. These 
autogenerated addresses are in the range of 169.254.x.x. If your IP 
address is in this range, check the connection from the PC to the 
UTM and reboot your PC.

If your UTM’s IP address has been changed and you do not know the current IP address, 
reset the UTM’s configuration to factory default settings. This sets the UTM’s IP address 
to 192.168.1.1. This procedure is explained in 

If you do not want to revert to the factory default settings and lose your 

configuration settings, you can reboot the UTM and use a sniffer to 
capture packets sent during the reboot. Look at the ARP packets to 
locate the UTM’s LAN interface address.
