Airport Randomly Shuts-Off; Reboot Will Temporarily Solve The Problem

Ever since I've bought my Mac (July 2010) I've been having trouble with the Airport. I'll be browsing the net and all of a sudden my pages won't load, it just stops. The Airport icon in the menubar shows full signal, but when I go into System Preferences it says that my Airport if "Off." When I click the button to turn it on it acts like a dummy button, it just doesn't do anything. I can click it twenty-times and my Airport will still be off.

I doubt this is a router problem as I have tried this with various routers at various places. I took it into the local library, a hotel, a local gas station that has Wi-Fi and it continues to happens. Not to mention that the Airport itself shuts off. This really ***** when you're in the middle of a 1GB update and it just stops...then you have to start over.

After I do a complete reboot the Airport is on again, well most of the time. Sometimes it just stays off and I reboot it again. Sometimes it stays on for three-days and sometimes it stays on for five-minutes and I have to reboot six times or so until it stays on for a while. The average is about 30minutes until it shuts down again.

I've tried reinstalling my operating system, delete preference files, deleting my Airport connection and then recreating it, updating my Mac, trying different firewall settings, I tried booting in 64bit mode. Nothing seems to work. I tried an Apple Hardware test two times. One time I just did it and it reported no problems. The second time I waited until it shut down but it reported nothing, although I think it's because I rebooted and the Airport was "fixed" and it detected nothing.

I thought this was just something temporarily when I got my Mac so I waited and didn't call support. After 8months I decided to call support and they want $50 to try to diagnose it for me, which isn't fair because it happened from day one and I just thought an update or something would fix it. Not to mention, that a Genius Bar will look at it for free (two hours away from the closest one). Any hints, ideas, or tips? Thanks.

Thanks.


Possibly. I've been wondering, based on the conversation I've seen online, if there might not be multiple problems with the same, namely these, symptoms. I can hope...


Ah. I'm interested because I do rather rely on WiFi and I already ordered a dongle. And no, it certainly wouldn't be preferable to the internal AirPort if the internal AirPort was still working properly.


10.6.8, though for a very brief period today I was running 10.6.6.

Here's something I tried. So far it has worked, but I don't want to get too excited yet. I'm giving you everything I did <b>exactly</b>, so some may or may not apply to you.


Created a new network location.

Left Wi-Fi as the only network option (removed Ethernet and FireWire)

Advanced... > Check "Require Admin Authorization to Turn Wifi On/Off"

Advanced... > TCP/IP > Configure IPv4 using "BootP" > Configure IPv6 "Automatically"

Advanced... > Hardware > Configure "Manually" > MTU "Custom" > in the box enter "1280"


"Ok" everything, and then "Apply"

Reboot


Let me know if you need clarification. And keep in mind I'm on 10.8.2, so stuff might be a little different from 10.6.x.

Well, thanks for the advice, but I won't be able to try it for 3-5 days and hopefully won't need it. This morning I had slow booting and buggy, freezing wake-from-sleep issues. This ended with a visit to an Apple store and a professional diagnostic. It looks like the _AirPort card_ is fine; the problem is the _Bluetooth_ card, which I never use... but in my model, the two share a card mounted in the screen hinge. The wake-on-sleep issues were caused by a corrupted file, and the boot issues were apparently just the computer being confused. They're replacing the combined card, which they think will fix the problem. I know that it didn't for you, but your lack of described other issues and the fact that Apple didn't find anything wrong with yours makes me think that we might actually have different problems with similar systems.

I'm afraid that I can't; I only know what the people at the Apple store told me, which wasn't much. I think that we must have had different issues, though, since the people who told you that you didn't have any hardware problems would have had to be extremely incompetent to miss the large red x that I got. I'm quite glad that you seem to have found a solution, though, and I hope that you're right that it's worked.
