10.6.8 killed my airport

here is the combo update

http://support.apple.com/kb/DL1399

you could try that.......it is 1.09GB and if you can only connect on wireless, obviousy, that won't work with a dropping connection.

You can download it via another computer and the install on your mac. alternatively you can connect by ethernet cable to your router.

i found the isue with mine is was iAntiVirus which was causing the issue (i think) it was not recognising the sleep and was still running a full hard drive scan. didnt seem to like 10.6.8 at all. have since deleted it and installed the Sophos Anti Virus (check App Store) which on first scan found 13 Java threats in cache!

all for Windows - but still they were on my machine!

Hello,

Got the same problem with my 13" early 2011 MBP. Upgraded to 10.6.8, then the next day Airport was showing some signs of malfunction, then on the afternoon no airport at all ("no card installed").

I've tried a SMC reset:

and it solved everything for me.

I'm still running 10.6.8 and airport is back to normal (note that in the meantime I reverted to 10.6.7 and airport was still down, so it's apparently nothing to do with 10.6.8 itself, but maybe with the 10.6.8 install which did something to airport that the SMC reset solved).

Good luck.

This problem goes back to 10.6.5. This solution from tenortim fixed my and others wireless connection problem after upgrading:

Say thank you tenortim.

I have the same issue as well on my mini's airport interface. i had no issues with connecting to internet over wifi until i upgraded to 10.6.8. Now, i have issues connecting to the wifi, intermittent connection and very slow speed even if i get hooked up.

I tried all the techniques laid out in this thread -

1. SCM
2. PRAM
3. Deleting the plist file in Library-->Preferences
4. Installing the 10.6.8 combo rev 1.1

Nothing is helping.

Instead of waiting for another update or a rev 1.2, i have decided to go back to the original snow leapord version that is available on my DVD. Hopefully that should fix the issue.

when i first got my Laptop with 10.6 i had this exact same issue. it got fixed when i managed to get the update to 10.6.2, which at the time was the newest version. to get this, i had to use another computer to download the combo update, then transfer it via usb key - it fixed the problem immediately. i would suggest - and some others are suggesting that you try installing the 10.6.8 combo update - as that may fix any airport issues.

i, myslef had a problem with 10.6.8, which i have never had before. my computer now does not sleep - well i think that is the issue - when i closed the lid of the laptop - with no aplications or programs running - the apple light went off, and the sleep light at the front of the laptop came on - but when i returned i found the computer hot!

and the battery completely dead and all my network preferences reset!

I am facing the same issue too with my 27" iMac but interestingly, not with my MBA 13" (mid 2010). It's very irritating as my router is too far away for me to use wired ethernet. I hope apple fixes this soon

thanks umma08. I actually tried the combo update (used my MBA to download it and transferred it via USB to my iMac) but my WIFI still drops although less frequently now. I notice that it occurs especially after the iMac enters sleep mode and is reawaken.

Hi M,

I had exactly the same issue - although triggered by a previous system update. I used iStumbler to track the Airport connection and discovered the card in the MBP would intermittently just stop transmitting. I presume the offending update had shortened the time-out value so it was now more apparent.

Anyway to cut a long story short a visit to an Applestore and one new Airport card later and it was sorted,.

Regards,

Shawn

Same here. I installed 10.6.8 on my 11" Air and suddenly, my entire WiFi network was down. I can't even get a connection on my iPhone. I now have 10.6.8 on my Air and iMac, and Airport is broken on both. I installed the combo on my iMac and had no change. This is SO annoying. Seriously, Apple?

Anyone have any luck getting their connections back? Is it just an Airport-to-Mac issue, or are your iPhones, iPods and iPads messed up, as well? I can't believe an OS update messed my Airport Extreme up so bad that NO devices will work.

After the 10.6.8 update the Airport file permissions were possibly not returned to their original state.

Open Disk Utility in the Utilities folder, select your boot drive and Repair Permissions, enter the admin password if necessary.

Log into a admin account and run Software Update so Airport gets updated. Also toggle your System Prefrences > Secuirty > General > "Auto-update safe downloads list" on and then off.

After that download and run ALL the cleaning and maintenance aspects of the free OnyX and reboot.

And then use OnyX > Verify > Preferences (check the box for show only corrupted ones) and write down all the corrupted .plist files.

Use the free Easy Find to seek and Trash those .plists (or move them to the desktop) and reboot. They will get automatically rebuilt (minus your preferences of course which you need to reset.)

Geez, that's a lot to have to do to fix a crummy OS update. I'm honestly not super confident in doing all that. Plus, how could this have messed up the actual Airport Extreme hardware? I'm shocked that even my i-devices and my wife's Windows laptop can't even get online. Any thoughts on that?

I have a 24" iMac w/10.6.7. Upgraded to 10.6.8 yesterday and couldn't get the Mac into my WiFi network. The Mac could "see" the network, but when I tried to join, the network was locked and my password was no longer recognized! My iPad continued to work flawlessly on the network. I reloaded 10.6.0 from the disk (my Wi-Fi network working fine), then tried upgrading to 10.6.8 with their "combo" upgrade package: same results. I'm now back to 10.6.0 (Wi-Fi back to okay), hoping that Apple will come up with another upgrade version soon. Shouldn't be this difficult.

yeah the combo update seems to clear things up - haven't the foggiest why, i just saw from another thread. i havent had the need to do the combi updat yet.....my issue was with iAntiVirus, so i uninstalled and installed Sophos Anti Virus - problems seem to have been sorted. weird by Apple to drop the ball.....

oh and with Apple support - i always find waiting till the afternoon and then calling the IS tech support much better - they seem to know a bit more out there - as getting on to a tech support person that knows $£*& all is soooooo frustrating!

Also check the time and date on your computer, make sure it's accurate.

If the Airport router still isn't working, then reset it and log into a Admin account and reconfigure it completely using the Airport Utility.

There was a security issue a short time ago and perhaps this update addressed that issue.

Contrary to my earlier message, the problem persists.

I check the functionality with a 12GB file that I try to copy to my Mac Mini (running 10.5.x). So far I tried all the suggested solutions:

- I downloaded and installed the 10.6.8 combo update

- permissions have been repaired

- time on my router and my MBP (i7) now match

- the SMC of the mbp has been reset

- the PRAM has been flashed

The symptoms:

o At some point the Airport stops functioning, or at least loses part of its funcionality. Sometimes it's after 20+ minutes, sometimes after 5 minutes.

o When it loses connection with my Mac Mini during the copying of the testfile, it subsequently also refuses to connect to my router's config page while other connections (through said router) to websites still work.

o Turning the airport off and on solves the above issues temporarily

THE QUESTION:

Could the fact that it refuses to connect to a certain IP address while still allowing connections to others suggest that there is some kind of security measure at work? Or am I jumping to conclusions...

Added later:

Also my iPhone is not functioning as smoothly it used to. Streaming with AirVideo from my Mac Mini (10.5.x) stops after a certain time. Duration of funcioning varies, again. Turning the WiFi funcionality of the iPhone off and back on allows playback to resume, suggesting that the problem is not the network (=router) or the Mac Mini.

Makes no sense, I know, but it can't be a coincidence.
