Chapter 6.0: Trouble Shooting
This chapter provides solutions to problems you may encounter during installation and operation of your router.

Hardware

Q: The Power LED is off.
- Check the power cable is properly connected to the router, the power adapter and the socket.
Q: The LAN Link LED is off.
- Check the computer, hub or switch is properly connected to the router.
- Check the computer's Ethernet card is properly installed.
- Check the 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 192.168.0.2 ~ 192.168.0.254 and is therefore compatible with the router's default IP address of
192.168.0.1 (3-3). Check also the Subnet Mask is set to 255.255.255.0
Q: The STATUS LED stays lit.
- The STATUS 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 lit, the device is experiencing a problem. Please contact your dealer.
Q: Why can't I configure the router?
- First, check whether the router is properly installed or not, it include the LAN and WAN connections, and all devices' power.
- Next, check the IP configuration of your PC:
For Windows 95,98 users: run Winipcfg.exe or Winipcfg from Run on the Start menu. If there is no IP address involved, click Release All and then click
Renew All to get IP address.
For Windows NT 4.0 users: run Ipconfig.exe or Ipconfig from Run on the Start menu. Ensure that your PC and the router are on the same network segment.
If you are not sure, initiate the DHCP function, let the PC get the IP address automatically.
Ensure that your PC is using an IP Address within the range 192.168.0.2 to 192.168.0.254 and thus compatible with the router default IP address of 192.168.0.1
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
Ping gateway IP (Default: 192.168.0.1) to check the internal link of network.
If you're not able to get to the web configuration screen for the router, make sure that you remove any proxy setting within your Internet browser, or remove the
dial-up settings within your browser.
Q: What can I do if I have forgotten the password for router?
- You have to reset router back to factory default setting by pushing the Reset button over 3 seconds, and refer to the instructions in the user's manual to
reconfigure the settings.
Q: I cannot access my ISP's home page, why?
- Some ISPs, such as @Home, require their host name be specifically configured into your computer before you can surf their local web pages. If you are unable to
access your ISP's home page, enter your ISP's Domain Name into the OnePage Setup (3-3) to enable all computers in your LAN to access it. If you only want to
allow computers to access these home pages, open the TCP/IP Properties window (2-4) on these computers, click open the "DNS Configuration" tab and enter
your ISP's Domain Name in the "Domain Name Search Suffix" location.

Client Side (Computers)

Q: I can't browse in the internet via the router
- Check the LAN Link/ACT LED on the front panel is lit to indicate proper connection between the computer and the router. Check if both ends of the network cable
are properly connected.
- Check that TCP/IP is setup on your computer (2-4). Run "winipcfg" under Windows 95/98 prompt MS-DOS or run "Ipconfig" under Windows NT prompt DOS.
Check that the computer's IP Address is in the range of 192.168.0.2 ~ 192.168.0.254 and the Subnet Mask is 255.255.255.0. If you are using a fixed IP address,
check also the Default Gateway IP Address and DNS address in "More".
Q: I get a time out error when I enter a URL or IP address.
- Check if other computers work. If they do, ensure the computer's IP settings are correct (IP Address, Subnet Mask, Gateway IP Address and DNS) (4-7).
