Common Problems and Solutions

This appendix consists of two parts: "Common Problems and Solutions" and
"Frequently Asked Questions." Provided are possible solutions to problems that
may occur during the installation and operation of the Router. Read the descrip-
tions below to help solve your problems. 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 on a PC.
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 ranges 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:
A. Click Start, choose Settings, and open the Control Panel. Then, double-
click Network.
B. In The following network components are installed box, select the TCP/IP-
Line associated with your Ethernet adapter. If you only have one Ethernet
adapter installed, you will only see one TCP/IP line with no association to an
Ethernet adapter. Highlight it and click the Properties button.
C. In the TCP/IP properties window, select the IP address tab, and select
Specify an IP address. Enter an 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 ranges 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.
D. Click the Gateway tab, and in the New Gateway prompt, enter 192.168.1.1,
which is the default IP address of the Router. Click the Add button to accept
the entry.
E. 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.
F. Click the OK button in the TCP/IP properties window, and click Close or
the OK button for the Network window.
G. Restart the computer when asked.
