macbook loses wireless connection after sleep

If I set my macbook to sleep when not in use, when I wake it up, it has lost its wireless connection. I am asked for my wireless password, and after entering it I get "connection timeout." The only way to get the connection back is to restart the computer. I am at a loss on how to fix this. Can anyone offer advice?

MacBook, Mac OS X (10.6.8)

Try the following, in order, until (hopefully) resolved:


1a. Delete Preferred Network(s)


  • System Preferences > Network > AirPort > Advanced > AirPort tab
  • Under "Preferred Networks," delete the network(s) you regularly use from the list.



1b. Delete AirPort Keychain Entries


  • Launch the "Keychain Access" application located in Applications/Utilties.
  • Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.



1c. Add Preferred Network(s)


  • System Preferences > Network > AirPort > Advanced > AirPort tab
  • Add the preferred network(s) using the "+" button.
  • Restart or log out then back in.



2. Move System Configuration Files (optional; only perform this step if the issue is not resolved in the above steps)

(Note: You will have to reestablish your network connections settings.)


  • Go to /Library/Preferences
  • Move the SystemConfiguration folder to the desktop.
  • Restart your Mac. (Note: OS X will rebuild the files that are now sitting on your desktop. If this doesn't resolve the issue, you can move the folder back to it's original location.)

Thanks so much for 1a - 1c. This solved a problem which was becoming increasingly more irritating!
