MacBook Pro loses all 802.11 signals - reboot required - not a router issue

Recent intermittent problem on my MacBook Pro, but happening often enough to need to address:
For some reason the wireless networking (internal "airport card") will lose reception. It drops its current connection when this happens, and the menu bar icon loses all its signal bars and shows that it's scanning, but can't find anything.
I have 4 different wireless routers in the house (2 Apple, one Linksys, one Verizon) and my neighbors have a couple that always show as available in my Airport menu, but when this issue occurs, none of these 6-7 routers show as available, even though two iPhones and two other laptops in the house have no issues.
I've tried turning off the internal airport card and turning it back on with no luck. Only a full power off reboot of the computer fixes the problem.
The problem is random, so hard to troubleshoot, and I don't think it's faulty hardware (or a simple reboot wouldn't fix it), but I don't even know where to begin looking for software type issues.
Any ideas?

I also have the Verizon router. What I did was piggy back my Airport Extreme (802.11n) to the Verizon router. I paid too much $$$$ for the AE to not use it.
Thanks for the reply, +but this is NOT an issue with an AE Router.+ I tried to make that clear. +This is an issue with my MacBook Pro+. All other devices in the household (2 laptops, 4 iPhones, 2 Airport Expresses, an AppleTV) have zero issues with my wireless networking, and my MacBook Pro cannot see any networks, regardless of the brand of router that is running, and regardless of the location.
I suppose a cross post to the AE forums wouldn't hurt, but they seem very focused on AE ROUTERS over there, and I suspect I won't get much replies beyond "what are your router settings" or "reboot your router."
Thanks again.

    No and Yes
    Don't use TM for this purpose, clone your drive to an external, plug the external into another MBP and reboot from it. Please note that booting a machine that came with Lion may not be possible from a drive with Snow Leopard.

    Are you trying to open the backup files via the Finder or an application?  If so, that's not how you should access your backups -- use the "Star Wars" display, per #15 in Time Machine - Frequently Asked Questions.
    How did you get your stuff on the new Mac? 
    It sounds like you may have skipped the offer to transfer it when your Mac first started up, created a user account, then used the Migration Assistant app instead.  If so, that may be the problem;  doing it that way means you end up with an extra user account, and can lose permission to files on other volumes, especially backups.
    Please clarify just what you're seeing, and whether you still have the old Mac.

    My daughter has had her Razr for about 9 months now.  About two weeks ago she picked up her phone in the morning on her way to school when she noticed two cracks, both starting at the camera lens. One goes completely to the bottom and the other goes sharply to the side. She has never dropped it and me and my husband went over it with a fine tooth comb. We looked under a magnifying glass and could no find any reason for the glass to crack. Not one ding, scratch or bang. Our daughter really takes good care of her stuff, but we still wanted to make sure before we sent it in for repairs. Well we did and we got a reply from Motorola with a picture of the cracks saying this was customer abuse and that it is not covered under warranty. Even though they did not find any physical damage to back it up. Well I e-mailed them back and told them I did a little research and found pages of people having the same problems. Well I did not hear from them until I received a notice from Fed Ex that they were sending the phone back. NOT FIXED!!! I went to look up why and guess what there is no case open any more for the phone. It has been wiped clean. I put in the RMA # it comes back not found, I put in the ID #, the SN# and all comes back not found. Yet a day earlier all the info was there. I know there is a lot more people like me and all of you, but they just don't want to be bothered so they pay to have it fix, just to have it do it again. Unless they have found the problem and only fixing it on a customer pay only set up. I am furious and will not be recommending this phone to anyone. And to think I was considering this phone for my next up grade! NOT!!!!

    So in the last few days I’ve noticed that pressing my volume change keys actually isn’t changing the volume on my macbook pro at all. When I press the volume up or down keys, it makes the recognisable pop sound but stays at the same volume while the squares go up or down. I mute it but my computer still makes sound. It’s the same with the volume control up the top of the screen, too. I slide it up and down and it doesn’t change the volume at all. The only way I can change the volume is with my speakers or the program I’m in (iTunes, VLC etc). I restarted and it seems to be okay then I go to change it a couple minutes later and it’s back to not working again.
    I’ve checked my settings- the “use all F1, F2, etc. keys as standard fuction keys” is not switched on, and I have tried a suggestion of moving the com.apple.systempreferences.plist file out of the library and onto the desktop and restarting and neither of those seem to make any difference whatsoever. I’ve tried to find online forums but the only suggestions I found were those two and they didn’t work.
    I’m just annoyed because I usually have the worst luck with technology but my macbook had been going strong and I got it because of the apparent lack of things that could go wrong, but of course even if there is one thing that could go wrong it will happen to me.
    Please help!

    If my iphone, ipad, MAC and macbook pro are all linked, and then I upgrade only my ipone to IOS 7.0, does that have an effect on the linking to my other MAC products.  It seems my calendar has lost a lot of information since the upgrade.

    If you purchased Lion for your iMac, just log into the Mac App Store from your MacBook using the Apple ID under which you purchased Lion and go to the Purchases page. You will be able to download and install Lion there. 
    searching the internet i found a link to upgrtade to 10.7
    The only place you get get Lion is from the Mac App Store. If you found some other site, that was an illegal copy and almost certainly tied to someone else's Apple ID and hence unusable by you. If the link was just to the Mac App Store, see above.
    As to the problem with synchronization to iCloud, that's not a 10.6 question, so I'd suggest you take up that specific issue in either the Lion or iCloud forums, providing full details, and someone there can probably help you sort things out.

  • HT3819 I have a new apple MacBook Pro. All my music is on my old computer and on my I-Pod. Can I use home sharing to transfer my music onto my new computer?

    I have a new apple MacBook Pro. All my music is on my old computer and my i-pad. What is the easiest way to transfer my music onto my new
    computer?

    apps
    If you have an iPod touch or iPhone with iOS 4 or later software, or an iPad, you can use iTunes to transfer files between your computer and an app on your device that supports file sharing.
    You might want to do this if, for example, you want to save files you create on your device to your computer, or take files with you so you can use them when you’re away from your computer.
    You don’t need to sync your device to transfer files, but your device needs to be connected to your computer.
    For information about supported apps, see the documentation for your apps.
    Hide
    To transfer files from your iPod touch, iPhone, or iPad to your computer:
    Connect your iPod touch, iPhone, or iPad to your computer.
    In iTunes, select your device (below Devices), and click the Apps button.
    Below File Sharing, from the list on the left, select the app on your device that you want to transfer a file from.
    From the list on the right, select the file you want to transfer, and click “Save to.”
    In the window that appears, select the destination where you want to save the file, and click Choose.
    The file is saved to the selected destination on your computer.
    SImport music and video already on your computer
    If you have audio or video files on your computer, you can import them into iTunes so that they appear in your iTunes library.
    Hide
    Here are ways to add items from your computer to your iTunes library:
    Drag a file or folder from the Finder to the iTunes window.
    If you add a folder, all the files it contains are added to your library.
    In iTunes, choose File > “Add to Library,” locate a file or folder, and then click Choose.
    By default, iTunes places a copy of each audio file in the iTunes folder (Home/Music); the original file remains in the current location. For information about adding an alias to the file (instead of creating a copy), see Add items to your library without copying them to your iTunes folder.

    The ipod is not a backup/storage device.
    You need to copy everything from your old computer to your new one.
    The Apple store will do this for you,  you can call apple support and they will help you, you can use google.

    Can not start up on my Macbook pro. All I get is a grey spinning wheel. Tried all the Startup key combinations and nothing works. I reset the NVRAM and nothing. I booted with start up disk , ran disk repair and all is ok. Tried to re-install OS but when I get to designating drive its blank. When I go to startup disk there is a "?" mark. When I restart under startup disk search for a drive it still comes up with nothing.  Before I got the grey spinning wheel I had a locked screen. Could not move curser or click on anything. Finally just shut down. Thank you in advance for any help!

    Shouldn't still have a 'beachballing'... if the drive is being found and the system is trying to boot from it but is having problems, I would suggest looking over ds store's user tip - Step by step to fix your Mac.
    It's likely either something corrupt in your system files or a failing hard drive. But follow ds's steps until you find the cause of the problem.
    Good luck,

    If you are using Lion:
    Dealing With The Resume Feature of Lion
    Managing Mac OS X Lion's application resume feature.
    If you shutdown your computer you should get a dialog asking if you want applications to resume on the next startup. Simply uncheck the box to prevent that from occurring. Open General preferences and uncheck the option to Restore windows when quitting and re-opening apps. You can also install a third-party utility to control resume features on individual applications: RestoreMeNot or Application State Cleaner.
    It is possible to completely stop the Resume feature although I'm unconvinced that it is that annoying. Nevertheless see the following:
    If you have not yet done so you must first make your /Home/Library/ folder visible. Open the Terminal application in the Utilities folder. At the prompt paste the following command line:
    chflags nohidden ~/Library
    Press RETURN. Quit the Terminal application.
    In the Finder navigate to the /Home/Library/Saved Application State/ folder. Delete the contents of the folder. Back up to the /Home/Library/ folder. Select the Saved Application State folder. Press COMMAND-I to open the Get Info window. In the Sharing and Permissions panel at the bottom click on the lock icon and authenticate. Set each of the listed entries to Read Only. Close the Get Info window.
    Quit all open programs except the Finder (this is very important.) Next, navigate to the /Home/Library/Preferences/ByHost/ folder. Look for a .plist file with "com.apple.loginwindow." in the file name followed by some numbers in hexadecimal. Select the file. Press COMMAND-I to open the Get Info window and in the Sharing and Permissions panel click on the lock icon and authenticate. Set each of the listed entries to Read Only. Close the Get Info window. If you also find a file with the same filename but with a last extension of ".lockfile," then you should delete it.
    The above should eliminate the Resume feature system-wide. Note that any future system updates or upgrades will likely undo these changes. You will then need to repeat this procedure assuming there are no major changes in OS X related to it.
