Chapter 6: Trouble Shooting
This chapter provides solutions to problems you may encounter during installation and
operation of your NetComm NB2800 Router.
Hardware
T: The Power LED is off.
Check the power cable is properly connected to the NetComm NB2800 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 NB2800 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 NB2800 Router?
First, check whether the NetComm NB2800 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 NB2800 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 NB2800 Router’s default IP address
of 192.168.1.1
■
Finally, use the 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.
■
Ping the Router’s IP address (Default: 192.168.1.1) to check for IP connectivity between
your computer and the Router.
