Q: Internet disconnects randomly everyday!

Hi everyone,

 

I've been having this internet issue with my 27" iMac for a couple of months and the support just doesn't seem to be helpful at all.

 

I'm connecting through wifi, however the internet disconnects itself every couple of hours, while everything looks fine (wifi status in the menu bar looks fine) but the internet just won't work. I could fix it easily by going to "System Preferences" - "Network" - "Assist me..." - "Diagnostics", as soon as I select my WIFI network, the internet will start working again. 100% of the times this will work. I don't have this issue with any other mac's in house so it's unlikely that something's wrong with my router.

 

Anyone had the same issue?

 

I'm pretty fraustrated as I've been a big fan of Apple and this is driving me nuts. Any help or advice is much appreciated.

 

Best,

iMac, OS X Mountain Lion (10.8.4)

    Hi, this has worked for a few...

     

    Though all of these steps may or may not be needed, I'm including them all.

     

    Make a New Location, Using network locations in Mac OS X ...

     

    http://support.apple.com/kb/HT2712

     

    10.5, 10.6, 10.7 & 10.8…

     

    System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.

     

     

    10.5.x/10.6.x/10.7.x instructions...

     

    System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.

     

    The interface that connects to the Internet should be dragged to the top of the list.

     

    If using Wifi/Airport...

     

    Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.

     

    For 10.5/10.6/10.7/10.8, System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...

     

    208.67.222.222

    208.67.220.220

     

    (There may be better or faster DNS numbers in your area, but these should be a good test).

    Click OK.

    First, there is no chance whatsoever that changing your DNS settings will have any effect on the problem.

     

    Back up all data before making any changes.
         
    Step 1
      
    Take all the applicable steps in this support article.
      
    Step 2
       
    If you're running OS X 10.8.4 or later, run Wireless Diagnostics and take the remedial steps suggested in the summary that appears, if any. The program also generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.

    Step 3

    If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. Continue if you find that Wi-Fi is faster with Bluetooth disabled.

    From that same menu, select Open Bluetooth Preferences. If the box labeled Discoverable is checked, uncheck it. Click the Advanced button, and in the sheet that opens, uncheck the top three boxes, if any are checked. Click OK. Enable Bluetooth and test again.

    If the application called "Bluetooth Setup Assistant" is running, quit it.

      
    Step 4

    This step will erase all your settings in the Network preference pane. Make a note of them before you begin, and recreate them afterwards. It may be helpful to take screenshots of the preference pane.

    Triple-click the line below on this page to select it:

    /Library/Preferences/SystemConfiguration

    Right-click or control-click the highlighted line and select

    Services Reveal

    from the contextual menu.* A folder should open with an item named "SystemConfiguration" selected. Move the selected item to the Trash. You may be prompted for your administrator password.

    *If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). In the Finder, select

    Go Go to Folder...

    from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.

    Reset the System Management Controller.

    Step 5

     

    Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

    Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional — ask if you need guidance.

    If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

     

    Keeping your confidential data secure during hardware repair

    *An SSD doesn't need to be zeroed.
