10.5.6 Breaks WiFi and How To Fix It

Just FYI out there.
10.5.6 messed up my WiFi for the third time this year and I fix it again by replacing the IO80211Family.kext file in //System/Library/Extensions/ folder with a version from 10.5.2
I don't know what exactly happens, but since I normally sit far away from my WiFi router, my connection gets unusable after the upgrades to 10.5.4, 10.5.5 and now 10.5.6. It works fine if I'm closer to the router but somehow having a weaker signal makes it very unreliable. I have never experienced that behavior with a PC system at the same spot in the house and as I said above, it gets totally fixed by replacing the file above.
APPLE, ISN'T IT TIME TO ADDRESS AND FIX THIS ISSUE. MAYBE YOU NEED TO INCLUDE DETAILED HACKING INSTRUCTIONS TO THE NEXT UPDATE SO PEOPLE CAN FIX THE MESS IT CREATES.

I'm glad this works for you, despite the security holes and changes in operation you introduce into your system by doing this.
There are also a significant number of people who report 10.5.6 fixed their Wi-Fi issues.
*So I appreciate you've had problems, but Apple hasn't "fixed this issue" because as far as they can tell, yours isn't a general case bug.*
Have you opened an AppleCare case for your issue or opened a bug via the Apple Bug Reporter?
By the way, despite what others say, my MacBook Pro was migrated from a PowerPC iBook and I've had no Wi-Fi issues whatsoever, so it's not necessarily a bad move.
This is the exact same thing that's happening to me (and thousands of others) so I'm not sure how much of a "general case bug" it needs to be for Apple to get off their cans and do something about it.
I appreciate you appreciating that we have problems, but if we've tried EVERYTHING, the only thing we can do is wait on Apple to fix the mess THEY'VE made.
By the way, it's taken 20 minutes to post this due to constant connection drops. I can't file a bug report as someone else mentioned because I can't stay connected long enough for the page to load.

  • What is the best app for following of the download? I mean how much I downloaded using WIFI and how much 3D download.

    I would like to follow the amount of MB I downloaded and to know how much data was downloaded using WIFI and how much using 3G (internet connection by phone network provider as AT&T and so...).
    Thank you very much for any suggestions.

    Personally I have tried LogMeIn Ignition, Splashtop, and AlwaysOnPC, as well as TeamViewer. Although LogMeIn Ignition is expensive I would also have to say that it is the best one I've tried. Apart from viewing the computer's screen, you can access the files and folders in a standalone file browser interface without seeing the computer's screen, this speeds things up a lot.
    As for security, I'm not too sure, as the website for LogMeIn does not seem to list the details. But as with any other internet based service, like email and social networking sites, an additional account of any sort will increase your vulnerability, even if it's just by that small amount. You can try accessing the computer through a VPN when on a public wifi network for added security. However about the virus, I don't think that is possible... No need to worry about your iPad getting a virus.

  • Macbook air Wi Fi and sound stops every time it goes to sleep. i have to  restart it every time to use wifi and sounds. this started happening just after the latest upgrade to X. any reasons why its doing that and how to fix it.

    Macbook air Wi Fi and sound stops every time it goes to sleep. i have to  restart it every time to use wifi and sounds. this started happening just after the latest upgrade to OS X. any reasons why its doing that and how to fix it.

    Test after taking each of the following steps. Back up all data before making any changes.
    1. Make sure the network is on the preferred list by following these instructions. It's important to read the article carefully, as it's the starting point for any further efforts to solve the problem. If you skip any of the steps, the problem may not be solved.
    2. Follow the instructions in this support article under the heading "Symptom: The network connection drops unexpectedly."
    3. Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
    4. From the Location menu at the top of the Network preference pane, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.
    5. Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
    6. In some cases, the problem has been resolved by repairing permissions on the startup volume.
    7. Turn off Bluetooth and test.
    8. Reinstall OS X.

  • Xperia Z2: 10 Problems Users Have, and How to Fix Them

    10 annoying issues with the Sony Xperia Z2, and how to fix them
    http://www.digitaltrends.com/mobile/xperia-z2-problems/
    I found this article by @digitaltrends on Twitter as I'm researching the Sony Xperia Z2. I hope these issues have been address, especially WiFi dropping. I'm interested in the Z2 because of the Noise Canceling feature, now I will have to do more research to find out which phone is more stable (even though it's a software thing).
    Can anyone with xperince with Z1, Z2, Z3 which they feel is the most stable for daily usage and heavy videoing projects? Realiability being the key?

    I have the Z1 and have no issues at all - I find that article a load of tosh, How can something be an issue if the owner hasn't read the manual and as an example turned on Tap to wake or are using a 3rd party charger and wonder why charging takes a long time - These are not issues with the phone merely issues with the owner

  • IPad audio  output is not working properly, except on Siri. Any ideas on what is wrong and how to fix it?

    iPad audio output does not work, except for on Siri. The mute button is not on, and the volume buttons have no effect/ don't work (unless Siri is open). I have reset the iPad, tried iOS7 and iOS8 resets, which didn't help. The audio output mostly works when headphones are out in, but has a tendency to cut out from time to time. Without headphones, Audio might start working again briefly from time to time, but most the time it doesn't.  Any ideas on what is wrong with it and how to fix it?
    my iPad is a 3rd gen, 16GB wifi only model, if that helps
    I did take it to an Apple Store, but the inncorrectly insisted that my speaker was bust and it would cost £250 to replace the whole iPad!

    iOS 8 isn't even out yet. If you are running iOS 8, I assume you are a developer and if you are, you are in the wrong forum to try to get help. If you are not a developer and you're running iOS 8, maybe that's why you are having problems on the iPad.

    The type that I made bold doesn't make sense. Is this a typo and you mean that " headphones are not in"?

    And you know they are incorrect because you get sound here and there from time to time? That fact doesn't prove that something isn't working correctly inside. You could very well have a bad connection inside the device causing this, but somehow you seem to know that's not the case.

  • Itunes crashes when iTunes Match runs its Step 3 (not before) - any ideas why and how to fix it?

    Every time iTunes runs the iTunes Match, when iTunes MAtch gets to Step 3 - iTunes stops working - ie crashes. Any idea why and how to fix it? The songs are still uploaded to iCloud etc... but it crashe iTunes every single time

    I cannot explain the failure, but I can tell you that I have a string of approx. 24 emails with Apple and a combined 10hrs of talk time with Apple customer reps that tried helping me precisely for the issue that iTunes Match would crash at Step 3 without fail. Apple even logged my Console and I was talking to an engineer that literally wrote part of the code for iTunes Match (that was the fourth and last level of customer care I was escalated to). The poor man almost quite his job, and I just about demanded a refund for my $25, since iTunes Match simply wasn't working.
    Then I studied at a friend's place, and I noticed that all of a sudden, while iTunes was running in the background, half my library was already uploaded and things were progressing smoothly. It turns out that it had something to do with my modem specifically, as I had already hooked up my computer straight to the modem, taking the router (TimeCapsule) out of the equation. Nothing worked. Firewalls were turned off, no AntiVirus existed, and Apple engineers tried everything possible, incl. remote access on my computer, to get this to work. Nothing worked as long as I was connected to a Motorola Surboard.
    At every other network, wether at Starbucks, my university, or at friends places, however, iTunes Match worked flawlessly.
    After some research online, it turnes out that a handful of people with Motorola Surrboard Xtreme cable modems had similar issues. Eversince, I simply use my neighbors wifi should I need to upload songs, and I have no issues. Oddly enough, matching (not uploading) works just fine with my Motorola.
    Don't ask me how or why, I am interested in computers and work with them a lot, but I am no engineer. I can tell you that simple scientific method pinpointed to the modem, and I haven't had issues since then.

    My Macbook pro is rejecting my Iphone 5 charger
    Do you actually mean the white cable with a lightning plug on one end and a USB on other
    If so that is not the charger ,that is the cable
    The charger is the device that plugs into the mains socket
    If so
    cable may be faulty if less than 12 months old take it to Apple Store genius bar for checking

    Welcome to the Apple Community.
    If your problem persists get yourself a micro USB cable (sold separately), you can restore your Apple TV from iTunes:
    Remove ALL cables from Apple TV. (if you don't you will not see Apple TV in the iTunes Source list)
    Connect the micro USB cable to the Apple TV and to your computer.
    Reconnect the power cable (only for Apple TV 3)
    Open iTunes.
    Select your Apple TV in the Devices list, and then click Restore.
    (You may already have a micro USB cable if you have a camera or other digital device)
