I couldn't use WiFi in my 2009 MacBook Pro. I check it from System Preferences but it looks like I don't have any WiFi card. Just Ethernet and Firewire etc. I re-installled Snow Leopard but it isn't a solution.

Macbooks use airport as their wifi. if you want to check if you have a airport card, go into system preferences, and check if there is an airport setting. if there is a red circle, its off, if its a yellow circle, then its on, but not connected to any network

Sometimes performing a PRAM reset on your laptop will sort out WiFi and Bluetooth issues.
Restart the computer, and before the grey screen appears, hold down the Command(?), Option, P, and R keys simultaneously. Keep the keys down until the computer re-boots again and you hear the startup chime for the second time. It should work after that.

To remove and replace the WiFi card in a MacBook Pro A1286, you will need to follow these steps:
  1. Shut down your MacBook Pro and disconnect the power cord.
  2. Turn the MacBook Pro over and locate the battery. Remove the battery by pressing the battery release latch and pulling the battery out of the computer.
  3. Remove the screws that hold the bottom case in place. There should be 10 screws total, including two hidden screws underneath the rubber feet.
  4. Lift the bottom case off of the MacBook Pro and set it aside.
  5. Locate the WiFi card, which is located near the center of the motherboard. It should be a small rectangular module with an antenna attached to it.
  6. Disconnect the antenna cables from the WiFi card by gently pulling them out of the connectors.
  7. Remove the screws that hold the WiFi card in place. There should be two screws total.
  8. Lift the WiFi card out of the motherboard and set it aside.
  9. Insert the new WiFi card into the motherboard and secure it with the screws.
  10. Reconnect the antenna cables to the new WiFi card.
  11. Replace the bottom case, making sure to align the holes with the screws and secure the case with the screws.
  12. Replace the battery and power on the MacBook Pro to test the new WiFi card.
Note: Be sure to handle the WiFi card carefully, as it is a delicate component and can be damaged easily. If you are not comfortable performing this repair, you may want to consider taking your MacBook Pro to a professional repair service.

check your network settings in system preferences. Is there a green dot next to airport? Ethernet? Check your modem and router for your connection.

Could not connect to campus wifi through leopard
You may need to access the network with the ASCII password. Is there a system administrator you can contact to get this code? It will be a very long string of characters and replaces the typical password you seen in many Airport type setups.
