Troubleshooting

I can't connect to the Configuration Utility of the 4-Port Broadband Router.

Possible Solution:
Make sure all the Ethernet cables are properly and securely connected and the power cord is plugged in.

Possible Solution:
Make sure that you correctly performed all the steps in the Before you begin section of this Guide. If you have a Static IP address and did not select the Obtain an IP address automatically option for your computer, you will not be able to connect to the 4-Port Broadband Router.

Possible Solution:
Make sure that your PC is using an IP address that is within the default range of 192.168.123.xxx. Make sure the address of the subnet mask is 255.255.255.0. If necessary, the Default Gateway and the DNS server data should also match the information you collected earlier. To verify all these settings, perform the following steps:

Windows 95, 98, or Me Users:
Click Windows Start and then Run. Type winipcfg and click OK. Check the IP Address, Subnet Mask, Default Gateway, and DNS server data to make sure they are correct. If the information is not correct, click Release All and then click Renew All.

Windows NT, 2000, or XP Users:
Click Windows Start and then Run. Type cmd and click OK. At the DOS prompt, type
ipconfig /all. Check the IP Address, Subnet Mask, Default Gateway, and DNS server data to make sure they are correct. If the information is not correct, type
ipconfig /release and press Enter. Then, type ipconfig /renew and press Enter.

If you are still unable to connect to the 4-Port Broadband Router, refer to the ping procedure below.

Possible Solution:
You need to verify the connection setting of your Web browser and that the HTTP Proxy feature of your Web browser is disabled. You need to do this so that your Web browser can read the configuration pages inside your 4-Port Broadband Router. Launch your Web browser.

Internet Explorer users: Click Tools, Internet Options, and then the Connections tab. Select Never dial a connection, click Apply, and then click OK. Click Tools again, then click Internet Options. Click the Connections tab, and click the LAN Settings button. Clear all the check boxes and click OK. Click OK.

Netscape Navigator users: Click Edit, Preferences, and then double-click Advanced in the Category window. Click Proxies, select Direct connection to the Internet, and then click OK. Click Edit again, then click Preferences. Under Category, double-click Advanced, then click Proxies. Select Direct connection to the Internet and click OK.

I can't access the Internet.

Possible Solution:
Make sure the power cord and all the Ethernet cables are connected correctly. This includes the cables connecting the 4-Port Broadband Router, the modem, and all the PCs.

You can also reboot the 4-Port Broadband Router by unplugging and plugging in the power supply. If you are still unable to access the Internet, refer to the Troubleshooting Ping Procedure section in this Guide and refer to the documentation for your modem.

I do not know if my assigned IP Address is Static or Dynamic.

Possible Solution:
If you have Cable or DSL service, you most likely have a Dynamic IP address. You should always check with your service provider to verify this information, since some providers will assign Static IP addresses. If you have a Dynamic IP address, select Dynamic IP Address in the WAN Setup area of the Configuration Utility and the 4-Port Broadband Router will automatically obtain the information it needs from your service provider. If you have a Static IP address, select Static IP Address in the WAN Setup area of the Configuration Utility. You will need to refer to the network connection information you collected earlier and manually enter this information.

My Cable or DSL service is not working, but I need to access the Internet.

Possible Solution:
If you have an external analogue modem and dial-up Internet service, you can still access the Internet. Connect the external analogue modem according to the procedure described in this Guide. Open a Web browser and type http://192.168.123.254 to access the Configuration Utility. Click Setup, WAN, and then select Dial-up Modem. Enter the appropriate information for your dial-up Internet Service Provider settings.

While trying to check my network configuration settings in Windows Me or XP, I can’t find the Network icon.

Possible Solution:
The default setting in Windows Me and XP is to not show all of the icons within the Control Panel. Click Windows Start, Settings, and then Control Panel. Within Control Panel, click View all Control Panel options on the left side of the screen. All the Control Panel icons should now be visible.

I do not know how to configure the TCP/IP protocol to work with the 4-Port Broadband Router.

Possible Solution:
You have the TCP/IP protocol installed, but it is not configured to work with the 4-Port Broadband Router.

1. Click Windows Start, Settings, then click Control Panel.
2. Double-click the Network icon. Click the Configuration tab and select the TCP/IP line that has been assigned to your network card.
3. Click the Properties button to set the TCP/IP protocol for the 4-Port Broadband Router.
4. There are two setting methods to configure the IP:

• To obtain the IP automatically through the DHCP server, perform the following step:
  Click the IP Address tab, and select Obtain an IP address automatically. This is the preferred method for configuring PCs.
  
  
• To configure the IP manually, perform the following steps:

1. Click the IP Address tab. Click Specify an IP address. Enter values in the IP Address field and in the Subnet Mask field. The default IP address of this product is 192.168.123.254. You should use 192.168.123.xxx (xxx is between 100 and 199) for IP Address field and 255.255.255.0 for Subnet Mask field.
2. Click the Gateway tab. Add the IP address of this product (default IP is 192.168.123.254) in the New gateway field and click Add.
   

Contact your ISP to get the necessary DNS values. Click the DNS Configuration tab. Add the DNS values into the DNS Server Search Order field and click Add.

After installing the TCP/IP communication protocol, you can use the ping command to check if your PC has successfully connected to the 4-Port Broadband Router.

Troubleshooting Ping Procedure

If at any time during the ping procedure you do not receive a return message for a successful ping, this means that the address you are pinging has been changed and is causing a conflict. Check the address in the configuration utility and make any necessary corrections using the console mode. After you have made the corrections, continue with the ping procedure.

1. Click Windows Start and then click Run. In the Run dialog box, Windows 95, 98, and Me users should type command and click OK. Windows NT, 2000, and XP users should type cmd and click OK.
2. Type Ping 127.0.0.1. This is your local host address and this will ensure that the TCP/IP protocol is installed and functioning properly. If you cannot complete this ping, disconnect the router and then repeat the installation procedure.
3. Type Ping followed by your IP address. This will ensure that your PC is responding to requests. If you cannot complete this ping, make sure all the cables are properly connected and that all the correct drivers are installed.
4. Type Ping followed by your gateway address to check the communication with your gateway. The default gateway address is 192.168.123.254. This will ensure that you can connect to other machines and can get to the 4-Port Broadband Router. If you can establish communication with the 4-Port Broadband Router, you can access the Administration page and configure the settings. If you cannot complete this ping, make sure the power cord of the 4-Port Broadband Router is plugged in and that it is properly connected to your PC or Macintosh.
5. Type Ping followed by the outside Internet address of your 4-Port Broadband Router. This is the address that is provided either by your ISP or by the outside LAN. This procedure will ensure that your 4-Port Broadband Router is functioning properly and allowing traffic to pass through.
6. Type Ping followed by your known DNS server address. This will allow you to resolve valid Internet host names to IP addresses and to verify that you can access the Internet.
