This chapter provides solutions to problems you may encounter during installation and operation of your NetComm ADSL Modem Router.

Hardware

T: The Power LED is off.

Check the power cable is properly connected to the NetComm ADSL Modem 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 ADSL Modem 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.

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 ADSL Modem Router?

First, check whether the NetComm ADSL Modem Router is properly installed or not, 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 ADSL Modem 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.

■Ensure that your computer is using an IP Address within the range 192.168.1.2 to 192.168.1.253 and thus compatible with the NetComm ADSL Modem Router’s default IP address of 192.168.1.1

■Finally, use Ping command in MS-DOS mode to verify the network connection: ■ Ping 127.0.0.1 to check the TCP/IP stack of your computer.
