After updating to Yosemite 10.10.2, macbook air Wifi does not work. What to do?

I upgraded from Maverick  to Yosemite in Nov 2014 & my mack book air 2011 model became slow. Yesterday after downloading & updating 10.10.2,  Wifi does not work, it prompted Gatway Time out. Anybody can help please? Dr. Mostafa

Moreover I am to add, in the same network, windows PC Wifi works & more interestingly Macbook with Maverick also connects with the same Wifi, I mean to say this is the problem with Yosemite 10.10.2. Before updating on Sunday last, my Wifi was working nicely.

    after hibernation, when trying to login to MacBook Air, it does not accept my password. I have to shut off and then get prompted with the following: Mac OS X wants to use the "login" keychain. I put in the password there and it works. any suggestions?

    Back up all data.
    Launch the Keychain Access application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Keychain Access in the icon grid.
    Select the login keychain from the list on the left side of the Keychain Access window. If your default keychain has a different name, select that.
    If the lock icon in the top left corner of the window shows that the keychain is locked, click to unlock it. You'll be prompted for the keychain password, which is the same as your login password, unless you've changed it.
    Right-click or control-click the login entry in the list. From the menu that pops up, select Change Settings for Keychain "login". In the sheet that opens, uncheck both boxes, if not already unchecked.
    From the menu bar, select
    Keychain Access ▹ Preferences ▹ First Aid
    If the box marked Keep login keychain unlocked is not checked, check it.
    Select
    Keychain Access ▹ Keychain First Aid
    from the menu bar and repair the keychain. Quit Keychain Access.

  • After updating my MBP to firmware 1.1 my internet does not work anymore

    Please help,
    A couple of days ago my MBP asked me if I wanted to update to Firmware 1.1 and I did. I followed the steps like it said and when I restarted it my internet was not working anymore. I called my internet provider and they tried helping me but no luck.They gave me the codes and I tried to set up the PPP address and other codes.
    I am using a DSL cable and a Ethernet connection.
    Does anyone know how I could solve this?
    Thanks!

    Try resetting your iPad:
    Double click the Home button. Slide up with one finger on ALL your apps to close them.
    Then, Press the Sleep/Wake button + Home button and hold 15 seconds or until you see the Apple logo.
    This will reset your device without erasing data, apps or settings.

  • My macbook air camera does not work

    I have a macbook air 11" mid 2011   running OSX Yosemite 10.10.1  
    I need to use the facetime camera, but it says no camera is available. 
    what I have done (6 hours or research and grief later):
    After reading a plethora of forums,  I have tried:
    Migrated from OSX Mountain Lion to Yosemite..  will definitely fix your problem.   no good... 
    Installed the latest update...  yep... 
    used the disk Utility repair again just in case...   yep...   still no good.
    restarted the computer...  yep.       no good...
    open a terminal and type         sudo killall VDCAssistant
    yep that was a waste of time...  its not even on my laptop.  
    the USB camera is not in the System Information USB Tree. and under camera it says no video capture devices were found.
    Found a really helpful UTube video which suggested I Kill off a Parrot thingy...   wasnt even in the devices list...
    I have read through the plethora of forums on this problem even further... there are literally thousands of them.
    The most popular answer which Apple appears to provide is:    and by the way you keep running into this suggestion...
    One of these will fix your problem:
    (1) If restarting your Mac doesn't fix the problem,                          (NOPE  didnt fix it..)
    (2) use Apple's http://support.apple.com/kb/HT2090                      (NOPE  no help...   as:
    did the use Disk Utility to repair permissions thing..   yep...  still no camera...
    the USB camera is still not in the System Information USB Tree.
    (option 3 applies to me...   cant see the camera in the USB...  
    no suggestion on how to resolve that ...  but there is a (4) so I tried that...  
    I reset the SMC ...   guess what...   still no camera...  
    The camera used to work...  
    ...............................................................................      My thought and question of Apple is below  ...................................................
    I am thinking the port on which the camera communicates is disabled in the new software version, or it is reassigned to something that is in conflict with it.  The USB connection is set at the manufacture level to something which is not being detected now.
    CAN APPLE PLEASE ADVISE ME WHICH DEFAULT PORT THE CAMERA IS CONNECTED TO AND CONFIRM THAT IT IS NOT DISABLED BY DEFAULT
    Please dont tell me its a problem with the camera...   I could probably roll back to the old software, and my system would work just fine...   this has been a total pain in the neck...   and has cost me many hours...  
    Yes I am going into the Apple store tomorrow... another two hours out of my life...  probably to be told its a hardware issue and they need to take it away and charge me money to fix it..     but I will take it there and decline to pay any money.   It is out of warranty and probably not essential to the laptop to use.   It s frustrating that there is no easy fix to this problem despite the plethora of forum articles and posts by thousands of people experiencing the same problem.
    There is no way Apple can stick its head in the sand and claim its a hardware issue.  
    I have tried to look for a built-in USB camera driver for Apple Macbook Air...   good luck with that...   If the old system driver was about,  perhaps someone could check the communications ports and work out where this problem actually sits.

    There was a final outcome...       Apple determined that the IO card was faulty and they replaced it under warranty..      The camera is working correctly
    i cant argue with the results...     The card replacement has reliably fixed the problem.   
    SO my final recommendation for a solution is
    check online to make sure you can get an appointment at your APPLE shop.   
    Book the appointment so you don't waste 4 hours...   
    Check that your machine is in warranty.      If not, the repair cost to me was $85 aus...    Still not too bad considering this issue cost me 14 hours of research and a further 8 hours travel time...   
    BAck up your computer and open the password to protect your regular one.  Then...
    take it to Apple at the appointed time.     MAKE SURE YOU BACKED UP YOUR MACHINE...
    WAit 5 to 10 days based on how busy they are...          If they say your card is faulty, it's hardware and no amount of fiddling about with software is going to fix the problem.        I could have saved 18 + hours..    
    Replace  the IO Card Fixed this issue...       It has not failed since getting the computer back.

  • My macbook air bluetooth does not pair with a bluetooth speakers!

    Recently I bought this http://www.amazon.co.uk/gp/product/B00MPT631O?psc=1&redirect=true&ref_=oh_aui_de tailpage_o01_s00 speakers it pairs with my Iphone 5 perfectly, but when I try to connected to my macbook air, it does not work for me  it shows the following window, which cannot get connected to the speakers, thanks in advance for any help

    While it appears that the Mac is discoverable, since it is not seeing the speakers, you may need to check the documentation that came with the speakers to see if they are in discovery/pairing mode, and how to get them into that mode. Then try and pair them.

  • HT2090 my macbook air camera is not working

    My Macbook Air camera is not working when I try to use photobooth. I have no problem with google hangouts or skype. How can I resolve this problem?

    • Restart your Mac. If the problem continues, use the Disk Utility in your Mac's Finder > Go > Utilities folder to repair permissions.  Then test the camera again.
    • If the your trouble persists,.  reinstall OS X Mavericks.  Repair permissions again immediately following the restart that completes the reinstall and before testing the camera again.
    •  Also check your Mac's  > Software Update... or Apple - Support - Downloads for latest Mavericks updates applicable to your Mac model such as OS X Mavericks 10.9.1 Update.

    You haven't identified the version so I can't tell if offering you contact options for Adobe Support will be of use to you.  But they will likely be your only hope of getting resolution unless you just happen to be using the wrong number as the serial number.

  • After upgrading iOS 7 on my iPhone 5, the wifi is not working . It cannot detect any wifi nor am I able to enable wifi under settings. Is there a way for me to fix this?

    After upgrading iOS 7 on my iPhone 5, the wifi is not working . It cannot detect any wifi nor am I able to enable wifi under settings. Is there a way for me to fix this?

    Hi samer almasri,
    If you are having issues with enabling Wifi on your iPhone you may want to try a couple of things to troubleshoot. First of all I would quit all open applications on the phone and try again. See this previous thread for how -
    How do I close apps on my iPhone with iOS 7?
    https://discussions.apple.com/thread/5581063
    Next, I would try restarting the iPhone -
    Turn your iOS device off and on (restart) and reset
