Appendix A:Troubleshooting
This section provides possible solutions to problems regarding the installation
and operation of the Cable/DSL Router. If your situation is described here, the
problem should be solved by applying the corresponding solution. If you can’t
find an answer here, check the Linksys website at www.linksys.com.
1. I need to set a static IP address.
The Router, by default, assigns an IP address range of 192.168.1.100 to
192.168.1.150 using the DHCP server on the Router. To set a static IP address,
you can only use the range 192.168.1.2 to 192.168.1.99 and 192.168.1.151 to
192.168.1.254. Each PC or network device that uses TCP/IP must have a
unique address to identify itself in a network. If the IP address is not unique to
a network, Windows will generate an IP conflict error message. You can assign
a static IP address to a PC by performing the following steps:
For Windows 95, 98, and ME:
1. Click on Start, Settings, Control Panel. Double-click on Network.
2. In The following network components are installed box, select the
TCP/IP-> associated with your network adapter. If you only have one net-
work adapter installed, you will only see one TCP/IP mention with no asso-
ciation to a network adapter. Highlight it and click the Properties button.
3. In the TCP/IP properties window, select the IP address tab, and select
Specify an IP address. Enter a unique IP address that is not used by any
other computer on the network connected to the Router. You can only use
an IP address in the range 192.168.1.2 to 192.168.1.99 and 192.168.1.151
to 192.168.1.254. Make sure that each IP address is unique for each PC or
network device.
4. Click the Gateway tab, and in the New Gateway prompt, enter 192.168.1.1,
which is the default IP address of the Cable/DSL Router. Click the Add but-
ton to accept the entry.
5. Click the DNS tab, and make sure the DNS Enabled option is selected.
Enter the Host and Domain names (e.g., John for Host and home for
Domain). Enter the DNS entry provided by your ISP. If your ISP has not
provided the DNS IP address, contact your ISP to get that information or go
to its website for the information.
6. Click the OK button in the TCP/IP properties window, and click Close or
the OK button for the Network window.
7. Restart the computer when asked.
