Appendix A: Troubleshooting
This appendix consists of two parts: “Common Problems and Solutions” and
“Frequently Asked Questions.” Provided are possible solutions to problems
regarding the installation and operation of the 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 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, Settings, and Control Panel. Double-click Network.
B. In The following network components are installed box, select the TCP/IP->
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 a unique IP address that is not used by any other com-
puter 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 net-
work 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.
Common Problems and Solutions

Basic Rates. The basic transfer rates should be set depending on the speed
of your wireless network. You must select 1-2 (Mbps) if you have older
802.11 compliant equipment on your network, such as wireless adapters
that support only 1 or 2 Mbps. Selecting 1-2 (Mbps), however, does not
limit the basic transfer rates of faster adapters.
TX Rates. Select all the supported rates at which the Router will commu-
nicate with your wireless network.
Preamble Type. The preamble defines the length of the CRC block for
communication between the Router and the roaming Network Card. (High
network traffic areas should use the shorter preamble type.) Select the
appropriate preamble type and click the Apply button to set it.
Authentication Type. You may choose between Open System, Shared
Key, and Both. The Authentication Type default is set to Open System, in
which the sender and the recipient do NOT share a secret key. Each party
generates its own key-pair and asks the receiver to accept the randomly-
generated key. Once accepted, this key is used for a short time only. Then
a new key is generated and agreed upon. Shared Key is when both the
sender and the recipient share a secret key.
Antenna Selection. This selection is for choosing which antenna transmits
data. By default, the Diversity Antenna selection, used to increase recep-
tion, is chosen.
