Connect a Mac (Tiger 10.4) to a WPA Wireless Network

In my previous post, I reviewed the best settings to secure my wireless network. Now it's time to connect my Mac laptop, gforce, running Tiger (OS X 10.4.11), to my WiFi (802.11g) wireless network. Boot up, and follow these steps:

  1. Turn on AirPort. I use the AirPort menu to do this, on the right side of the menu bar. The "fan" icon changes from a hollow outline to grayed-out "radio waves".
  2. Select Other... network from the AirPort menu. This is required because I turned off SSID broadcasting when I secured my WiFi router.
  3. In the Network Name field, type the secret but memorable SSID.
  4. Select WPA Personal from the Wireless Security drop-down menu. Note: the specific WPA security protocol is set by the wireless router; you need to match the setting on the router with this menu pick.
  5. Enter your fearsomely strong password. Tip: unless you think someone is spying on you with high resolution optics, you can check Show password. It certainly reduces the typos.
  6. Click [OK].
That's it! You are online. Test it out by opening your favorite browser and surfing to you your favorite search engine.

The Closed Network dialog. Enter the SSID here.


After you select WPA, you can enter the password.


Tips
  • If you can't see the AirPort menu, you can turn it on here: System Preferences > Network tab; select Show: AirPort; check Show AirPort status in menu bar.
  • Also, while you are making changes to the AirPort preferences, you should consider selecting By default, join: Preferred networks. If this doesn't work as expected, select the line corresponding to the SSID you selected, move it to the top of the list, and click the [Edit...] button to ensure the WPA password is set correctly.
  • If you think you might be having problems with interference or a poor signal, perform these steps right next to the wireless router to bathe your AirPort card in the strongest signal possible..
  • Save your WPA password in your Keychain, where it will be safely encrypted, so you don't have to enter it every time.
