My wife's computer - a MacBook (13-inch, Aluminum, Late 2008) - has recently had a hard time with the AirPort card. After waking it from a sleep once, she told me that she couldn't connect. The network settings said the AirPort was off, but clicking "On" didn't do anything. She's running 10.6.3.
I tried creating a new location (it failed), as recommended. I repaired permissions (several hundred were fixed) and trashed com.apple.airport.plist. I rebooted. It worked.
She slept the computer and it failed again. I reset the PRAM and rebooted. It didn't work. I rebooted and it worked the next time. Then she sleeps it and it goes away.
I took the computer apart so far as taking the battery, HD, and RAM out, but wasn't sure where the AirPort card was located to check for a loose connection. Someone on this page says I'd have to remove the Camera cable guide, LVDS cable guide, Display assembly, and Display clutch cover to get to the AirPort card, and while I'm technically quite capable of doing so, I'd prefer to know what parts those are (a diagram and some pictures) before I go that far.
I re-assembled the computer. The last post here implies that it's a faulty logic board. Well, that's no good. Another thread suggested I reset the SMC, so I did so, rebooted, and the AirPort came up just fine.
And that's where we currently sit - I'm not really willing to put the computer to sleep. I've gone back and forth on whether it's a software problem or a hardware problem, but I'm leaning heavily right now towards "hardware problem." The computer's obviously not under warranty, so unless there's a known issue with this, that's not going anywhere.
I am wondering if anyone knows of any suggestions. Is there a manual somewhere for locating (and checking the connections to) the AirPort card? Again, I've got the materials.
Any ideas at all?
