ARCHIVED: In Mac OS X, how do I configure my network settings to use my AirPort card?

Before connecting to a wireless network, you may have to configure your network settings to use AirPort. Normally AirPort is activated by default, but if it isn't, follow the instructions for your version of Mac OS X:

Mac OS X 10.5 and later

1. From the Apple menu, select System Preferences.... In System Preferences, from the View menu, select Network.
2. Look for "Wi-Fi" or "AirPort" in the list of network ports on the left side of the Network preferences window; the icon to its right will be a blue signal indicator. If it's there, skip to step 4. If it's not, follow the next step to activate it.
3. Near the bottom left of the Network preferences window, click + (the plus sign). In the sheet that drops down, next to "Interface:", select Wi-Fi or AirPort. Click Create.
4. Click the Wi-Fi or AirPort listing in the list of ports. If it says "Inactive", click the gear icon below the port list and select Make Service Active.
5. On the right side of the Network preferences window, there will be a "Status:" indicator. If it says "Off", click Turn Wi-Fi On or Turn AirPort On.
6. Click Advanced..., and then click the TCP/IP tab. From the menu next to "Configure IPv4:", make sure that Using DHCP is selected. Click OK.
7. Click Apply to save this configuration.

Mac OS X 10.4, 10.3, and 10.2

1. From the Apple menu, select System Preferences.... In System Preferences, from the View menu, select Network.
2. From the menu next to "Show:", select AirPort. If it isn't available, select Network Port Configurations and AirPort. Then, from the menu, select AirPort.
3. On the TCP/IP tab, from the menu next to "Configure:" or "Configure IPv4:", make sure that Using DHCP is selected.
4. Click Apply to save this configuration.
