I have an iMac 3.06 GHz Intel Core 13, running OS X V 10.8.4.


I am running an Apple Airport wireless router for my Mac devices in my home.


Lately, the iMac can't stay connected to the wireless connection.  I don't think it is Airport, because I can use my iPad at the same location, and it connects fine.


I am afraid I don't know exactly what I need to do to troubleshoot this.  I have gone through the assist me on the Network Preference pane and it says my connection is OK.


Does anyone have any ideas?

    Some users with various Wi-Fi connection problems have reported that they were given the following instructions by Apple Support, sometimes with success. I can't vouch for this procedure myself. After completing the procedure, you'll have to recreate all your settings in the Network preference pane. Make sure you know how to do that before you begin. Taking screenshots of the preference pane may be helpful.

    Step 1

    Back up all data.

    Triple-click the line below the line you're reading now to select it:


    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.

    Step 2

    Reset the System Management Controller
