IMac gets exclamation mark on wifi icon

Hi,
My iMac gets an exclamation mark this afternoon saying alert: no internet connection. In network setting it says self-assigned ip.  It worked perfectly before and all of a sudden it just won't connect to the Internet. My MacBook and iPad are able to connect to wifi so definitely some thing is wrong in my iMac. I got the exclamation mark once at school with my MacBook, but the problem seemed to be solve after one class which is 70 mins (I let it sleep and did nothing to it). Ive been trying to fix this problem with my iMac fir the whole afternoon but still get this exclamation mark.
I've tried: a. Turn off and on wifi.  B. Trying to delete plist files in library but I couldn't find them.  C. Renew DHCP lease  d. Create new location.  E. Restart
But no use. Any help?? Thanks in advance.
Mustache,

Would love to know this answer as well.  I have a MacBook pro and am staying at my daughters house. Last night I got on the Internet by typing in her password, but tonight I can't, however I am using my iPad.  How can I get a connection on one but not the other.  Very frustrating since my iPad won't open the connections I need to work on since they require flash.  Would love to know how to fix this problem.
A simple restart has solved it for me on the few occasions it has happened.

  • TS4611 exlaimation mark in wifi icon

    I have a macbook air purchased last fall.  Since I came back from a one-week trip around Christmas, I have been unable to connect to my home wifi network.  There is an exclaimation mark in the wifi icon.  I have several other devices (mac, iphone, ipad, pc), and most of them work fine - except my son's macbook pro and my wife's iPad.  We tried several recommended solutions - "forgetting" the network and re-establishing the connection.  I looked online for possible solutions, but so far, no luck.  What is going on?  Does anyone have any idea?

    When you see an exclamation point in the Wi-Fi menu, from the menu bar, select
     ▹ System Preferences... ▹ Network
    Click the Assist me button and select Assistant. Follow the prompts. You may get a warning that Wi-Fi is not available, that you're too far from the base station, or that you're using the wrong password.
    Assuming that you've ruled out those possibilities, restart the computer and try again. If there's no change, click the lock icon in the lower left corner of the preference pane and authenticate, if necessary. From the Location menu at the top of the window, 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  Applyand test.
    If there's still no connection, and if you have control of the router, compare its settings to Apple's recommendations. Some third-party routers may be incompatible in 802.11b/g/n radio mode. Try setting the mode to 802.11n only.

  • Exclamation Mark On Printer Icon

    Every time I print from my iMac to my HP Photosmart 5510 printer, an exclamation mark in a yellow triangle appears on the printer icon in my Dock, like this:
    What does this mean?
    The "Now Printing" window that pops up on my screen looks like this, again with an exclamation mark over the printer's icon:

    Hi Barry,
    The HP Photosmart 5510 is a new printer that came out this month (September 2011). The most recent HP Printer Software Update that Apple released via System Preferences>Software Update is version 2.7, which came out in early August 2011.
    So, the drivers for the Photosmart 5510 aren't available in Apple's HP Printer Software Update, yet.
    I had to download the drivers manually from HP's website, and install them myself. So yes, my software is up-to-date, but it's straight from HP, and not via Apple. I'm currently running Snow Leopard, but the same exclamation mark problem exists in Lion.

  • Exclamation Mark on wireless icon

    Hi,
    I have a MacBook 5,2 Intel Core 2 Duo 2.13 Ghz 2GB Memory running snow leopard. I connect to my personal wireless at home and a wireless at my university campus (set-up on campus).
    Since my upgrade to snow leopard I have had no issues at home however on campus the wireless icon shows an exclamation mark with a message on the drop down menu "alert: no internet connection". this happens on my university campus only (at least so far). The strange thing is the internet is working and I can browse/download etc. I have contacted the IT department on campus and they have said the issue has only started with people with snow leopard and have no idea. To clarify, the internet is working but I am being told it is not (on campus only, not the case at home). It is not a huge issue as I can access the internet but the exclamation mark is driving me crazy and cannot find a solution.
    Any ideas? anyone else encountered this issue? Thanks for your help!

    We too have similar problems. I have an older macbook with leopard and it's fine - but a new MBPro with snow leopard has all these problems.
    I was prompted to respond here in particular because when we tried to wirelessly connect the MBPro to my home router (it worked for about 30 seconds initially - internet connection as well, but then died) it not only doesn't work (and shows the exclamation mark) but it hangs the router - ie: the old macbook loses connection as well. The only fix here is to restart the router.
    This result is completely repeatable. Now (because we successfully connected for a few seconds with the correct wep password) all we have to do is open the lid of the MBPro and my old trusty macbook stops working as well!! (I can't ping the router at this stage either) Power cycle router and comes good again (having turned off airport on the MBPro).
    Now, at a different location our BT broadband has gone pear-shaped (almost brand new homehub looks as if it might have died) one wonders if the MBPro is suspect again..
    I do hope an OS update will fix this annoyance.

  • Why do I get exclamation marks beside my songs

    what do I do to get rid of these exclamation marks

    I have Exclamation marks by my songs but not in the itunes library itself, only when i try to download them into my phone. the URL below is a video showing my problem:

  • Red exclamation mark in battery icon

    I have Z30. When I am switching on my phone, first it shows the blackberry logo then a red battery icon with exclamatory mark shows and turns off. Device is not switchng on its showing the same thing also while connecting with charger. Please provide solution.

    I'm not sure. I was expecting you to respond that you had performed the recent upgrade to 10.3.1.
    Please bear with me. Try this. Plug your BlackBerry into a wall charger. Use a genuine BlackBerry charger. Don't use another brand charger or USB. Leave the device on the charger for 2 hours or more. Then, while plugged in, remove the battery. After a minute, put the battery back. Again, leave the device on the charger for two or more hours. Then check and see if the device has booted.
    It's also possible the battery is bad, or the device is broken. If the above doesn't fix the issue, you should try a known good battery in your device, and try your battery in a known good Z30. That should identify whether the device or the battery is the issue.
    If you bought your device through a carrier and it turns out from your troubleshooting that the device itself is in question, contact your carrier's customer support and ask for help and tell them the troubleshooting steps you have performed. If they can't solve the problem and the device is under warranty, make a warranty claim.

  • I keep getting exclamation marks on my playlist on itunes, but this is only for the songs downloaded on my phone. I can't play any songs on my phone, only on the original itunes library. Whats going on??

    but this is only for the songs downloaded on my phone. I can't play any songs on my phone, only on the original itunes library. Whats going on??

    The iPod backup that iTunes makes does not inlcuded synced media like apps and music. Thes those iTunes are not restored to the iPod unless they are in the iTunes library.
    Try:
    - 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.
    - Unsync all music and resync
    - 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.
    - Restore from backup. See:       
    iOS: How to back up
    - Restore to factory settings/new iOS device.

  • I can't get my music to play in my itunes. It comes with a exclamation mark next to the song numbers and says that the original songs can't be played cause cant find the file. How do I get the songs back? (I found the files)

    I can't get my music to play in my itunes. It comes with a exclamation mark next to the song numbers and says that the original songs can't be played cause cant find the file. How do I get the songs back? (I found the files

    You get exclamation marks or dead tracks because  iTunes can’t find the file. This can happen for a number of reasons:
    The song file or a folder in its path was renamed
    The song file or the folder it is in has been moved
    The song file has been deleted
    The device containing the song files e.g. external drive is not accessible or the drive letter has changed.
    If you use an external drive, a change in drive letter is a common cause and you need to change it back.
    AS a way of working out what has happened, right click on a track and select the summary tab (you will have to go past an error message). The summary tab will tell you where iTunes thinks the track is located. How does that compare with where the track actually is?
    The xml library file is not used by iTunes, it is created to allow other programs to access the library. You can recreate the iTl file from the xml file, but there is no point if the location of the files is wrong.
    There is a simple way of getting you music back in iTunes, but it loses all playlists counts and rating. To do this drag iTunes library.itl and iTunes Library.xml to your desktop. Then open iTunes and an empty library is created. Add you iTunes Media folder to it.
    If you can't work out what went wrong and how to fix it, you may have to do this.

  • "X" in the wifi icon of the toolbar

    Similar to "exclamation" mark that others have seen in the wifi icon in the toolbar, I am getting an "X" within wifi icon and cannot add wifi in settings. Has anyone had this issue that can help?
    I am running a mid-year 2011 MacBook Air with 1.7 Intel Core i5 / 4GB ram / 128GB of storage.

    Back up all data before proceeding.
    Open the Network pane in System Preferences. A list of available network services appears on the left. If Wi-Fi is in the list, select it, then from the popup menu labeled with a gear icon at the bottom of the list, select
              Make Service Active
    Click Apply.
    If Wi-Fi is not in the service list, click the plus-sign button at the bottom of the list, and then select Wi-Fi from the  Interface menu in the sheet that drops down. Click Create, then Apply.
    If there is a closed padlock icon in the lower left corner of the preference pane, click it and enter your administrator password to unlock the settings.
    If the above steps don't solve the problem, continue.
    Triple-click anywhere in the line below on this page to select it:
    /Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist
    Right-click or control-click the line and select
             Services ▹ Reveal in Finder (or just Reveal)
    from the contextual menu.* A folder should open with "com.apple.airport.preferences.plist" selected. Move the selected item to the Trash. You may be prompted for your administrator password. Restart the computer and recreate your settings for Wi-Fi in the Network preference pane.
    *If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination  command-C. In the Finder, select
              Go ▹ Go to Folder...
    from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.

  • Exclamation Mark instead of Pictures

    Until last week I was using 10.4.11 and iPhoto 7.1.1 without any problems of any kind. I then had a larker hard disk built into my MBP. The Service Technician installed 10.5.1 onto the new disk by accident and sinced then i keep getting exclamation marks from my folders in iPhoto instead of pictures or when i try to work on the pictures the window is blank though the strip shows th picture that should be being seen. Before i update to 10.5.4, I want to see if there is anyother way of solving this. The stores are open tomorrow but the technicians are not there till monday.
    The problem is somewhat critical because I need the pictures for my lectures and supervision this weekend.
    thanks in advance

    It sounds like your library got corrupted in the upgrade process - do you have a currect back up of the library6.iphoto file and/or of the entire library?
    If you have a backup of teh library6.iphoto file replace the on ein the corrupted library. Or If you have a total backup you should drag the iPhoto library from the pictures folder to the desktop and load the backup - if everything is ok delete the one from your desktop
    If you do not ahve backupas then quit iPhoto, backup your iPhoto library and try rebuilding the library - launch iPhoto while depressing the option (alt) and command (apple) keys - use the resulting dialogue to rebuild the library
    It that does not work download iPhoto lLibrary Manager and use it to rebuild the library (it creats a new library so you will still have the old one)
    If none of those work you will ahve to start over - quit iPhoto, drag the iPhoto library from the pictures folder to the desktop, launch iPhoto and create a new library - open the iPhoto library oin yoru desktop and drag each folder from the originals folder onto the running iPhoto (or onto the iphoto icon in the Dock) to create a new library with yoru old events - but no projects, albums etc

  • Exclamation marks next to songs

    I have a 33,000 song iTunes library stored on an external 1Tb USB2 drive that is permanently connected to my 20" Intel Core Duo iMac running the latest version of Leopard and iTunes. I keep getting exclamation marks next to songs and when I choose to loacted them thye are in the correct place. Sometimes its whole albums or one or two individual songs. Can anyone reccomend anyway to remdy this situation?

    Hi You are not the only one with this problem it seems that there are quite a few similar posts on this subject and no answers rather than going through one by one (no Thanks) or deletimg all files in iTunes and reloading over night (No Thanks!). This also means I will loose all my playlists!
    Please Apple answer this or remedy some kind of Playlist save!

  • TS1717 I have exclamation marks (!) which has ruined my playlist as it doesn't function as it should. I was downloading music when a scan had started which I cancelled.  Ever since then I've had these exclamation marks anyone know how to fix it?

    I have exclamation marks at the beginning of the titles which has ruined my playlist as it doesn't function as it should. I was downloading music when a scan started which I then cancelled as it was slowing down my download. Ever since then I've had these exclamation marks and now these tunes are not transferrable and I've lost them in my music file on the ipod nano and so cannot reload them again. Anyone know how to remove the !!!'s or clean my files?

    You get exclamation marks or dead tracks because  iTunes can’t find the file. This can happen for a number of reasons:
    The song file or a folder in its path was renamed
    The song file or the folder it is in has been moved
    The song file has been deleted
    The device containing the song files e.g. external drive is not accessible or the drive letter has changed..
    Usually the actual music files are still there, so you need to check to see if you can find them.
    If they are there, open iTunes and select a problem track, right click and select Get Info.
    Answer NO when asked if you want to locate the track.
    Now you should see where iTunes thinks the tack is located on the summary tab, how does this compare with where the track actually is.
    This info should help work out what has gone wrong.

  • Converting word file into PDF creates exclamation marks

    Hi,
    I have Word 2007 and Acrobat 8.1.7 (OS: Windows XP). When creating PDFs in Word i get exclamation marks at the end of a header, footer and body itself. I tried rebuilding font cache but that didn't help. I also uninstalled all Adobe components and installed them anew - didn't do anything either. Have no other ideas. Please help...
    Thanks!

    The key is the print preview. If they are there, then they are being produced by WORD, not Acrobat. At that point, the Adobe PDF printer driver has not come into play other than providing WORD printer metric information. Check your settins in WORD. You should also be getting the same result if you just printed to paper or any other printer.
