Airport turns off when my Macbook is put to sleep...ugh!

Hello. Can anyone help me? Just today, when I woke my computer from sleep mode, I noticed that my airport card had been turned off (by sleep). I went to Network Preference and told it to turn on airport. It did so great. I put the computer to sleep sometime later, then opened it again after lunch to find that sleep mode had turned off airport again. Now every time I wake the computer up, I have to go to network prefs select airport, turn airport on, etc. It never used to do this. How can I get back to what it was: airport NEVER turning off unless I did so manually? Thanks in advance.

Macbook, Mac OS X (10.5.4)

Since the Airport card is normally turned off during sleep, have you waited to see if the card turns on by itself (what it should do generally within 10-20 seconds.)

Yes, I've tried waiting, but it doesn't come on. Happening every time now.

Well, you might try navigating to the /Library/Preferences/SystemConfiguration/ folder and deleting the com.apple.airport.preferences.plist, com.apple.PowerManagement.plist, and preferences.plist files. Then restart the computer. You will need to reconfigure your Network preferences, so you may want to note down the particulars before deleting the aforementioned files.

Rebooted, and voila. Amazing what that can do! Thanks for all suggestions.

This exact same thing is happening to my MacBook. Everytime I awake from sleep, the airport is turned off. I will try this solution and report back.

this worked but running Leopard 10.5.6 there is no powermanagement.plist; just deleted the airport and that seemed to do the trick.

I was so excited to find this discussion, because I've been having this problem with my new-to-me refurb MacBook Pro for a while. But, I don't seem to have the three files you specify that I'm supposed to delete in my Preferences folder. What does that mean?

I do have
com.apple.preference.internet.plist
com.apple.internetconfig.plist
com.apple.internetconfigpriv.plist
com.apple.internetconnect.plist
com.apple.systempreferences.plist

So appreciate your help!
