TS4209 When i wake up my iMac from sleep my wifi is disconnected.  It also disconnects my iPad, my wives iPad, my iPhone & Sky On Demand which is connected via wifi. To reconnect all devices i have to switch off & then on again wifi on the iMac. Can anyon

When i wake up my iMac from sleep my wifi is disconnected.  It also disconnects my iPad, my wives iPad, my iPhone & Sky On Demand which is connected via wifi. To reconnect all devices i have to switch off & then on again wifi on the iMac. Can anyone help?

Had the same issue and finally solved it.  After the upgrade to Mavericks our 2 new Macbook Airs stopped connecting automatically to Wifi while the older machines the kids had still worked fine.
Bought a new airport extreme and problem solved.   Our Airport Extreme was about 5 years old and was probably not compatible with the new OSX.
BTW this was after trying everything people suggested on this forum and a 4 hour marathon tech support call with Apple where we reinstalled the OSX.
***** to need to spend $200 but glad the problem got solved.
New extreme is also mega fast so its all good.

    Thank you for such a quick response.  Most of the things brought out in the article I had already done, but there were some others that I would not have thought of.  Thank you again for directing me to this site.  I will have to see now if this will increase the battery life any.

  • Grey screen with message "turn off computer with power button until switch off then press again power button"

    Dear all,
    I'm very hungry with my iMac and my Time Capsule :
    I try for two weeks to restore my iMac without any success...
    I wait 80 hours to finally have the message again and again : "to restart your computer : turn off computer with power button until switch off then press again power button".
    But my iMac do not work !
    Could you help me?

    Hello, that's a kernel panic...
    http://thexlab.com/faqs/kernelpanics.html
    Could be many things, we should start with this...
    "Try Disk Utility
    1. Insert the Mac OS X 10.6 Install disc, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
    *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
    3. Click the First Aid tab.
    4. Select your Mac OS X volume.
    5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
    http://docs.info.apple.com/article.html?artnum=106214
    Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
    (Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
    If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.

  • After every Firefox 34.0 reloading my add-ons have been switched off by unknown program or virus. How can i solve this problem?

    After every Firefox 34.0 reloading my add-ons have been switched off by unknown program or virus. Although i can switch them on and reboot firefox to fix it, but it is a little bit boring. How can i solve this problem?

    Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.
    You can try these free programs to scan for malware, which work with your existing antivirus software:
    * [http://www.microsoft.com/security/scanner/default.aspx Microsoft Safety Scanner]
    * [http://www.malwarebytes.org/products/malwarebytes_free/ MalwareBytes' Anti-Malware]

    * [http://www.eset.com/us/online-scanner/ ESET Online Scanner]
    [http://windows.microsoft.com/MSE Microsoft Security Essentials] is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one.

  • When I wake my computer up from sleep all the Mail and Calendar accounts are offline?

    Now that I have upgraded to Mountain Lion, when I wake my computer from sleep all of my Mail and Calender accounts are offline. This includes Gmail, AOL, and iCloud accounts. The connection doctor in Mail says that Mail can connect to the internet but puts red dots next to all of my accounts stating that connections to both the IMAP and SMTP servers could not be made. This issue has shown up only after upgrading to Mountain Lion, and the only way to resolve it seems to be to manually quit and relaunch Mail and Calender at which point everything goes back to normal until I sleep the computer again. Any ideas?

    Further to my previous post... I think I may have stumbled uppon a solution.
    Summary: When I fixed a problem with dictation, mail started working again.
    Background: I noticed that after upgrading to 10.8.1 the dictation feature no longer worked. When I pressed [fn] twice the dictation bubble would appear, three dots in it would shake and then it beeped. No dictation. I searched for a solution, tried it out and dictation worked again. Then, this morning I opened up my Mac and mail sucessfully downloaded without having to restart mail.app!
    Solution: This is a fix for dictation issues so don't blame me if it messes up your perfectly working dictation! However, it appears to have fixed my mail problems:
    Locate and delete the file: ~/Library/Preferences/com.apple.assistant.plist (Finder’s Go and press and hold Alt option). Then restart your Mac, turn off Dictation (Apple > System Preferences, click Dictation & Speech, and then click Dictation) and reboot your Mac a second time and try again.
    The original thread is here.
    So, a random "solution" with beneficial side effects! Let me know it works for you.
    #Solution #Dictation #com.apple.assistant.plist
    #MBP #mail.app #10.8.1 #6.0 #not working after sleep #IMAP #Mountain Lion #Gmail #iCloud #Offline

  • Why is Firefox 4 freezing when I wake my Mac up from sleep?

    I just upgraded to FF 4. Every time I wake my Macbook Pro up from sleep mode (from having put it to sleep/closing the lid, with FF still running), FF freezes. This only began happening since I upgraded 2 days ago.
    It doesn't crash. Every other program that was running before works just fine, the mouse works, keyboard, etc. But FF appears frozen, won't actually open new URLs (it just sits there after I've typed a new URL or tried to use one of the tabs I had open from before putting it to sleep), and each time I've had to force quit FF and re-open, and then it works fine.
    This was not an issue with FF 3.
    Any ideas? I looked around for similar questions in the forum but only saw posts about FF crashing, not freezing.

    it's not a profile issue. or a concurrent firefox process issue.

  • When I wake my iMac from sleep, the wireless does not connect.  I have to shut shutdown and then restart and then it connects.  I am running Lion 10.7.3  Any thoughts?

    Been waiting along time for this problem to be fixed. Unfortunately the update hasn't help at all and even made the situation worse. Now my airplay connection from iMac to stereo abruptly stops after about 10-15 min. so I have to go over and quit wifi, start it up and find my airport network. Not sure why it always has a problem with the apple airport network. My neighbor's pc network is always there.

  • Problem - I input a new event into my iPhone calendar and it does not update on my iMac or iPad. I have loaded the latest software on all devices and have switched over to iCloud. Suggestions?

    Problem - I input a new event into my iPhone calendar and it does not update on my iMac or iPad calendars. I have loaded the latest software on all devices and have switched over to iCloud. Suggestions?

    On the iMac open System Prerferences > iCloud
    Deselect the box next to Calendars then reselect then restart the iMac.
    On the iPad, tap Settings > iCloud
    Switch Calendars off then back on then reset the iPad.
    Hold the On/Off Sleep/Wake button and the Home button down at the same time for at least ten seconds, until the Apple logo appears.
    Hopefully the event synced over all the devices.

  • Hello, I have a macbook pro late 2011 15 inch with 4 gb ram. My macbook runs extremely slow when logging in after waking up from sleep, locking up and I am unable to use the keyboard. Is there a fix?

    My macbook runs extremely slow when logging in after waking up from sleep, locking up and I am unable to use the keyboard. Furthermore, when just using safari to watch streaming television, my computer gets really slow, and locks up, and the dock appears blank and I sit here frustrated. Anytime i wake up my computer, my keys don't respond and I've waited at most 3 minutes untill i can type in my password. Even sometimes when i type in my password and hit enter, it takes forever to open up my mac. I have barely used any storage in my macbook, since i only use it for college, and I have run clamscan wiht no viruses showing... Any ideas?

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device. 
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output andWi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

  • Can't use mouse/keyboard/trackpad when waking iMac from sleep mode

    Basically as the title says. When I wake my iMac from sleep mode I am unable to use my keyboard/trackpad/mouse during the login window. Once the screen goes black by itself, after a minute or so I can then log in properly.
    Yes the keyboard/mouse/trackpad are all connected when it wakes from sleep as I can use any of them to wake it from sleep, I just can't move them or type with them in the login window.

  • Wake iMac from sleep remotely

    Cannot wake my imac from sleep remotely unless on own wifi network. Tried splashtop & logmein. Checked obvious on settings. Using airport extreme. Have set uo both VPN for access anywhere.

    Ok, all you should need to do is go into System Preferences --> Energy Saver  and make sure that the "Wake for network access" checkbox is checked.
    Your iMac should be connected to your modem via ethernet cable. If not it may not work, depending on what version of mac OS X you are running.  Again, you DO NOT need an AirPort Express to wake you iMac from sleep via LAN.  you only need to tell you iMac to wake from sleep upon LAN activity.
