Why does the wifi keep disconnecting on the Macbook Air (Bought September 2013) ?

Is this only my MacBook Air, or is it with everyones. The wifi keeps getting disconnected and i would have to switch off and then switch on the wifi in order to reconnect.

Hi Ettedos,
Thanks for visiting Apple Support Communities.
It sounds like you're seeing unexpected behavior on your MacBook Air.
I'd recommend starting with the Wireless Diagnostic built into Mavericks:
OS X Mountain Lion v10.8.4 or later
Use the Wireless Diagnostics application included with OS X Mountain Lion v10.8.4 and later to identify and resolve Wi-Fi issues. For further information, please see About Wireless Diagnostics.

    If you try by Ethernet you can verify if the issue is with your WiFi network or if your appletv is defect as most users do not suffer as you do

  • JSF : why does my menu keep moving to the middle...?

    Does anyone have this problem with their webpages using JSF? I have a menu on the left of my webpages, which keeps moving to the middle each time I make my page width smaller. Does anyone know why?
    thank you

    I have mine set to Snap to Grid and my Macintosh HD icon stays in the upper right corner, and I’m also using Spaces.
    Maybe if you try adjusting the Grid Spacing it would help.
    Or you could try moving the finder.plist file to the Desktop from your Users/yourusername/Library/Preferences folder and restarting. If that doesn’t fix it you can move the finder.plist file back to the Preferences folder to replace the new one it created.

  • Why does my mac keep disconnecting from my Wifi?

    After downloading Yosemite, my computer (macbook pro) keeps disconnecting my home wifi.  I had no problems with my wifi before and my roommates have no problems with it still (they do not have macs).  This is only happening at home though, when I go anywhere else, my wifi stays connected.  I have tried deleting/forgetting my wifi network and reconnecting, restarting my computer, i searched through my settings but I don't know what to do. It disconnects like every two minutes. When it disconnects and i go to reconnect, the wifi is still there and has full bars, my computer just doesn't stay connected to it.  If anyone has any idea what to do that would be awesome!

    Hey sydthekyd5,
    Thanks for the question. I understand that you are experiencing issues with your home Wi-Fi network. Check out the following resource for relevant information regarding your symptoms:
    Wi-Fi: How to troubleshoot Wi-Fi connectivity - Apple Support
    http://support.apple.com/en-us/HT202222
    Symptom: The network connection drops unexpectedly
    - Your Mac may not not stay connected to your Wi-Fi network reliably.
    - Your Mac may stop accessing the Internet during use.
    Solution
    Use these steps if your computer disconnects from its Wi-Fi network unexpectedly.
    1. Check your range to the Wi-Fi router and reduce the effect of interference.
    If your computer is too far from your Wi-Fi router or your environment has too much Wi-Fi interference, then your computer may not detect the Wi-Fi network properly. The easiest way to check for range limits with your Wi-Fi network is to move your computer or your Wi-Fi router closer together and make sure that there are no obstructions (such as walls, cabinets, and so forth) between the router and your computer.
    See Potential sources of wireless interference for more information about interference and solutions.
    2. Try connecting to a different Wi-Fi network. If your computer works fine when connected to a different Wi-Fi network, then the issue may be related to your network router or ISP. In that case, contact the manufacturer of your router or your ISP.
    Thanks,
    Matt M.

  • Why does my cursor keep disappearing in the Google search bar?

    When using FF or Google Chrome, I've noticed that my cursor keeps disappearing when using the Google search bar. I've tried using all the about:config tips, I've downgraded to earlier versions, I've pressed F7, I've unchecked the "hide cursor while typing" option in my mouse properties, I've checked for driver updates, I've tried disabling all add-ons and plug-ins, and I've checked another computer in our home as well. Same thing there. This seems to have become a problem in the last few days. IE seems unaffected by it. Just FF and Chrome.

    No sir, there are no other tabs open, when it happens. For now, I've found a workaround, and I invite you to test it yourself.
    I've been working on this problem all day. I've noticed that the cursor blinks very slowly in the Google search bar. If you press a key while the cursor is blinking "off", it will stay off until you let go of what key you're pressing. Conversely, if you press a key while the cursor is blinking "on", the cursor will remain visible as you type.
    In IE, the cursor blinks much more rapidly, and blinks more "on" than "off." As a result the cursor remains on, no matter what you type or when, or what key you press, including the spacebar. This is not the case in FF or Chrome.
    It was suggested in the Google forums that disabling "autocomplete" has helped with this problem. I followed the instructions and successfully disabled the "auto-complete" feature on Google. When I did that, I immediately noticed that the cursor blink speed doubled, like what I'm used to seeing. Further, no matter what I did, the cursor did NOT disappear anymore.
    The link for google with autocomplete disabled is http://www.google.com/webhp?complete=0
    Go there and see if you notice a difference in the blink speed of the cursor. On my computer, the difference is drastic. While I do enjoy "auto-complete" and will miss this feature, I generally don't rely on it, and much prefer a consistent cursor.
    I greatly look forward to your feedback on this. If you figure out a way to have Google work normally without this workaround, I will be forever in your debt.

  • Why does my 4s keep returning tot the boot screen (apple logo) when I press the home button to see the lock screen?

    3 or 4 times since I first fired up my iPhone 4S yesterday, it has displayed the boot screen (apple logo) when I press the Home button to display the lock screen. After 10-20 seconds the phone displays the lock screen, but at that point it has to search for a cell signal (as if the phone just booted up), which takes another 20-30 seconds.
    Is anyone else having this issue?
    Another thing that has happened only once, but that seems related, is that when I clicked the lock button on the top of the phone, the phone displayed the spinning circle that usually displays when an iPhone or iPad is shutting down.
    Any ideas on what MIT be causing this?

    Disk repair hasn't worked as well.
    I just wanted to add a quick observation: after I tried the TM restore for the first time, Safe Boot in verbose mode seems to be stuck at this line "VBoxAdpDrv: version 3.1.0 r55467". This may point to the problem being a Virtual Box problem.
    I use Virtual Box extremely rarely - haven't used it in many months. After a re-install, I'm going to remove it and then try the upgrade. If it works, then we've probably found the culprit. If it is real, Apple should maybe add a line saying Virtual Box known to cause problems with this upgrade (or fix it ).

  • Why does magic mouse keep disconnecting?

    I've got an Apple Magic Mouse  that is less than one year old and it keeps disconnecting from my Mac Mini.  It just started doing it.  I've put in fresh batteries and restarted the computer.   I've got all the latest operating system software.   Nothing is out of date.   Every couple of minutes it just randomlly disconnects then reconnects and so on, over and over again.  It's only about 2 feet away from my Mac Mini.
    Anybody know what to do?
    Thanks.
    David

    I thank you for your help, Ascendi, but I have no idea what you're saying.  I'm guessing I stand alone, because others do understand.  What I got from it was that the batteries don't fit snuggly, and to shove aluminum foil... somewhere.  I'm don't have a PhD in battery terminal dimensions and their terminonolgy.  But I do appreciate that you helped.
    David / Flashkube2... EXACTLY!  After years and years with my wonderful white Magic Mouse, just today the exact same thing started happening, only I was losing connection every 20 seconds.  Half the time, I'd get it back.  I feared it was a Bluetooth error, or a hacker was "stealing my juice"  So I got online here, read this stuff, wiggled my batteries around (for years and years, I've only used Duracel), and for the last 10 minutes, I have kept connection with Mr. Mouse and Mr. Mac.  Keep your fingers crossed!
    So if this problem arises again, I just stuff aluminum foil in there?  (I'll be a wee bit neater than "stuff").  Speak "positive terminal" and "negative terminal" and "top of the batteries" to me, because "depth of the recess" and "vernier caliper" are Chinese to me.  Does "battery recess" mean how the two batteries sit in its casing?
    Maybe I just didn't have enough coffee this morning.  I'm not ususally shtooo-pid.  (don't go there!)

  • Why does my ipod keep disconnecting and connecting every half a second?

    I had my iPod touch (4th gen, ios6) synced to a desktop and when I tried connecting it to my new laptop to sync it keeps connecting then disconnecting every half a second (flashing on and off) and will not connect at all. Do I need to do something with my old computer? I don't think it's something wrong with the cord because it connects to the wall just fine.

    Different conductors/contacts are used for charging and dats. Thus, it still could be a bad cable.
    - Reset the iOS device. Nothing will be lost      
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Reboot the computer
    - Try another USB port and cable
    - Iphone 5 lightning port charging problem - SOLUTION!
    - Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.
    - Reset all settings                 
    Go to Settings > General > Reset and tap Reset All Settings.
    All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
    - Try on another computer to help determine if iPod or computer problem
    - If it works with other computer that indicates a problem with your computer. Try
    Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP
    or              
    Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
    - Restore from backup. See:                                               
    iOS: Back up and restore your iOS device with iCloud or iTunes
    - Restore to factory settings/new iOS device.                       
    If still problem with all compouters, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

  • Why does my internet keep disconnecting on my mac?

    I bought a new mac this christmas, and so far the internet has been repeatedly disconnecting until I turn the wifi off and back on. I was okay the first time this happened but now it has been months. Its getting VERY annoying. How can I fix this?
    (My mac is a Macbook Pro OS X Yosemite.)

    How to check if there are other WiFi base stations near by
    Option-Click on the WiFi icon in your menu bar -> select Open Wireless Diagnostics
    Enter your Admin password when prompted.
    Wireless Diagnostics -> Windows -> Utilities -> Wi-Fi Scan tab
    Click [Scan Now] button in the lower right corner.
    You may want to grow the window to see all the columns
    The WiFi base station and channel your Mac is using will be "Bold" and all the other WiFi signals will be normal type.
    You are interested in the RSSI column and the Noise column
    The smaller negative value the stronger signal.  -37 is the strong signal in my house.  My nearest neighbor is -77.  In an appartment/condo complex you may have signals as strong or stronger than your signal.
    The Noise signal should be a large negative value. -88 to -90's indicates a very small amount of noise.  Noise is an indication of interference.  A large negative value indicates very little noise.
    Channels should not overlap.  The 2.4GHz channels should be 5 channels apart.  1, 6, and 11 are the preferred channels in countries that allow 1-11.  Some countries allow 1-13.  So you want to look for in use channels with a small negative RSSI values that are less than 5 channels away from your 2.4GHz channel.
    The 5GHz channels are assigned without any overlap, so they should not be a problem.
    ==============
    Change of subject
    Sometimes Bluetooth interferes with the 2.4GHz WiFi.  If you are using Bluetooth devices, try turning off Bluetooth on your Mac.  This is an experiment.
    Microwave ovens use 2.4GHz.  If your computer or your WiFi base station is picking up microwave oven leaking, then that can cause interference (the Noise above).  The reason WIFi is allowed to use the 2.4GHz frequencies is because that band if fill with too many interfering signals, such as Microwave ovens.
    2.4GHz cordless phones.  Yours or ones owned by your neighbors (assuming your neighbors are nearby, such as row homes, apartments, condos, etc... can interfere with 2.4GHz WiFi
    2.4GHz baby monitors are worse than 2.4GHz cordless phones, because baby monitors run all the time.  So if you are using, or a nearby neighbor is using a 2.4GHz baby monitor, that could be a problem.
    Buildings with metal framing.  Concrete with rebar, or some builders use metal studs.  These can block WiFi signals.

  • Why does my AIM keep disconnecting in iChat? (MacOSv10.7.5 iChatv6.0.2)

    I have recently updated to Mac OS Lion now at 10.7.5 & cannot upgrade to Mavericks as my machine is just under the requirements. Ever since I have made this upgrade, my AIM accounts on iChat have been logging themselves out in about under 5 minutes. I log them back in, but then same things happpen. To note, my GCHAT & JABBER accounts stay logged in without problem.
    How do I stop this from happening? I have read may of the previous reported issue & the results I have found instructions to delete the preference files com.apple.ichat.AIM.plist & com.apple.iChat.plist which i have done several times (deleting them before quitting & deleting after quit) but to no avail.
    My server setting for both accounts is..
    Server: login.oscar.aol.com
    Port: 5190
    This did not use to happen to me before the LION upgrade. I also use to have CHAX installed, but I have uninstalled it as I know it no longer works with 10.7 & above.
    Any trick here that I am missing?

    HI,
    I have Little Snitch to show me the pop ups to Allow the items for Messages (and previously iChat) when it launches.
    I believe you can set different option other than Allow Forever and Until Quit.
    The drop down shows me this:-
    I thinks that the Until Logout is you as the Mac User login rather than the Apps login to AIM.
    I have not tried using it this way.
    The "Once" item at the bottom might give clearer idea if you had to allow it each time it logged in.
    I am not quite sure what the Console messages is about.
    The URL would most likely be the IP address that you computer is at.
    About ten minutes might be Idle time  if you are not using the Keyboard or Mouse at all.
    Of course this message may have nothing to do with the Network dropping out.
    Something that happens regularly such as fetching Mail might be the cause.
