Chapter 7: Trouble Shooting
This chapter provides solutions to problems you may encounter during installation and
operation of your NetComm Cable/DSL Firewall Router.
Hardware
T: The Power LED is off.
Check the power cable is properly connected to the NetComm Cable/DSL Firewall Router, the
power adapter and the socket.
T: The LAN Link LED is off.
Check the computer, hub or switch is properly connected to the NetComm Cable/DSL Firewall
Router.
Check the computer’s Ethernet card is properly installed.
Check the UTP cable connecting the computer to the Router is connected. This cable should
not be a crossover cable.
Check the Cable/DSL Firewall Router and the computer are on the same network segment. If
you are not sure, initiate the DHCP function (4-1) and set your computer to obtain an IP
address automatically (3-3).
Check the computer is using an IP address in the range of 192.168.1.2 ~ 192.168.1.254 and is
therefore compatible with the Cable/DSL Firewall Router’s default IP address of 192.168.1.1 (3-
3). Check also the Subnet Mask is set to 255.255.255.0
T: The DIAG LED stays lit.
The DIAG LED should light up when the device is first powered up to indicate it is checking for
proper operation. After a few seconds, the LED should go off. If it stays on, the device is
experiencing a problem. Please contact your dealer.
T: Why can’t I configure the NetComm Cable/DSL Firewall Router?
First, check whether the NetComm Cable/DSL Firewall Router is properly installed, including
the LAN and WAN connections, and all devices’ power.
Next, check the IP configuration of your computer :
■ For Windows 95/98 users: run Winipcfg.exe or Winipcfg from “Run” on the “Start”
menu. If there are no IP addresses, click “Release All” and then click “Renew All” to get
an IP address.
For Windows NT 4.0/2000/XP users: Open a command prompt and run IpConfig.
■ Ensure that your computer and the NetComm Cable/DSL Firewall Router are on the same
network segment. If you are not sure, initiate the DHCP function and let the computer get an
IP address automatically from the router.
