Troubleshooting
I can't connect to the Configuration Utility of the 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 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 set-
tings, 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 O K. 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 ipcon-
fig /renew and press ENTER.
If you are still unable to connect to the Broadband Router, refer to the Troubleshooting Ping Procedure
section in the User Guide on the Installation CD.
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 configura-
tion pages inside your 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 Cate-
gory window. Click Proxies, select Direct connection to the Internet, and then click O K. 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 Broadband Router, the modem, and all the PCs.
You can also reboot the 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.
