After installing Snow Leopard I can't turn my Airport card on. I have tried both menubar icon and network selection. Interestingly it is not saying "airport card not installed". I have installed the latest Airport updates.
This problem has been driving me crazy, but I figured out a pretty good work around. Go to your network settings pref, click on airport, click advanced. Delete all the known networks included your own. Then hit apply. Then add your network by typing in the name/password - make sure you have the correct password type (i.e. wpa/wpa2 etc..) and then hit apply. That has connected me to my network each time I've been booted.
I have also gone into the airport utility and retyped the password info and restarted the time capsule before going into prefs, but I dont think you have to. Lemmie know how this works...
Try the following:
1. Delete Preferred Network(s) o System Preferences > Network > AirPort > Advanced > AirPort tab
o Under "Preferred Networks," delete the network(s) you regularly use from the list.
2. Delete AirPort Keychain Entries o Launch the "Keychain Access" application located in Applications/Utilties.
o Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
o Restart, or log out then back in.
3. Add Preferred Network(s) o System Preferences > Network > AirPort > Advanced > AirPort tab
o Add the preferred network(s) using the "+" button.
o Restart or log out then back in.
nope, still nothing after that. Thankyou for the in depth walkthrough though. My icon for Airport is shaded out, as in usually when it is off it is a black 'baseball diamond shape'? and when it is on black bars. now it is greyed out in the baseball diamond shape'.
Try creating a new Standard user account. Log off, and then, log back in with the new account. Is the AirPort status icon still greyed out? If it is, there may be something amiss with either the AirPort preference (.plist) or .kext files that did not transfer properly or got corrupted during the upgrade process.
Here are some additional troubleshooting steps to try if using a new user account does not solve the problem:
1. Switch Locations. In System Preferences > Network, create a new location which only includes the AirPort & Ethernet connectors. Be sure the AirPort connector is at the top of the list. Switch to the new location.
2. Check firmware version of the AEBSn to see if you are running the latest version.
3. Move AirPort configuration files to the OS X desktop. The following files are located in the /Library/Preferences/SystemConfiguration folder: preferences.plist, Networkinterfaces.plist & com.apple.airport.preferences.plist.
Note: Moving these files from their original locations will force OS X to recreate them.
3a. Move preferences.plist to the desktop. Restart the computer and check to see if the AirPort status icon is still greyed out. If it is continue with 3b.
3b. Move the Networkinterfaces.plist & com.apple.airport.preferences.plist files to the desktop, and then, check the AirPort status icon. Restart the computer, and then, check the AirPort status icon.
If moving all of these files does not resolve the problem, you can either move them back to their original locations (overwriting the new ones OS X created) or leave the new ones and delete the ones moved to the desktop.
Thank you for all of your help Tesserax. I tried making a new user account and logging into that, but unfortunately it didn't make any difference.
However Switching locations worked instantly.
"1. Switch Locations. In System Preferences > Network, create a new location which only includes the AirPort & Ethernet connectors. Be sure the AirPort connector is at the top of the list. Switch to the new location".
Deleting the preferences.plist, Networkinterfaces.plist, com.apple.airport.preferences.plist and creating a new location solved the problem for me without a reboot.
Thank you for these detailed instructions. I just returned from vacation, turned on my computer and couldn't connect to the Internet because "no AirPort card was installed." Your tip worked perfectly for me!!
