For some reason all of a sudden my iMac isn't remembering my home wifi network. Every time it goes to sleep, I have to reconnect my wifi. I have my preferences set for my home network being preferred. Does anyone know why this is likely happening?

iMac, Mac OS X (10.5.8)

    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 ...




    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/10.8.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.

    Test after taking each of the following steps. Back up all data before making any changes.

    1. Make sure the network is on the preferred list by following these instructions.

    2. Follow the instructions in this support article under the heading "Symptom: The network connection drops unexpectedly."

    3. Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.

    4. In some cases, the problem has been resolved by repairing permissions on the startup volume.

    5. Reinstall OS X.
