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 192.168.1.149 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 192.168.1.150 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:
Windows 98 and Millennium
Click 1. Start, Setting, and Control Panel. Double-click
Network.
In 2. 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 Properties.
In the 3. TCP/IP properties window, click 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 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.
Click the 4. Gateway tab, and in the New Gateway field,
enter 192.168.1.1, which is the Router’s default IP
address. Click Add to accept the entry.
Click the 5. 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.
Click 6. OK in the TCP/IP properties window, and click
Close or OK for the Network window.
Restart the computer when asked.7.
Windows 2000
Click 1. Start, Settings, and Control Panel. Double-click
Network and Dial-Up Connections.

box, select Internet Protocol (TCP/IP), and click

Enter a unique IP address that is not used by any other 4.
