Assigning a static IP address on a wireless Mac® computer

A static IP is an address that does not change.  Assigning your Mac® computer a static IP address allows it to use the same IP address every time.  This is useful when setting up public services (FTP servers, Web servers, etc.) and for easily mapping the Mac computer when it is frequently accessed on the network.

Before assigning a static IP address, you need to verify the following:

•    Ensure that you have an active Internet connection and the Mac computer is connected to any of the router’s four (4) Ethernet ports.  For instructions, click here.
•    Check the Mac computer’s TCP/IP properties if it is set to DHCP.  For instructions, click here.
•    Check the IP settings to find the Linksys router’s IP address.  For instructions, click here.
•    Check the DNS Server on a Linksys router through the web-based setup page.  For instructions, click here.

To proceed with assigning a static IP, follow the steps below:

Step 1:
Click the Apple icon then select the System Preferences… option.

Step 2:
Under Internet & Wireless, select Network.

Step 3:
Click the Advanced… button when the Network screen appears.  The default Location is Automatic.

Step 4:
Click TCP/IP.

Step 5:
From the Configure IPv4 drop-down list, select Manually.

Step 6:
Enter your IP settings in the required fields.

NOTE:  Make sure that the IP address you’ll be assigning the computer has the same first three (3) numbers as the Default Gateway and the last digit can be any number between 2 and 99.
