    OK, here's what worked for me.  I opened a terminal window and typed "ping (my website url)".  This works because my website will return pings.  So as long as I am continuously pinging it, I don't get disconnected.

    Ugly solution, but it works.  To use it, you will need to know a server to ping.  APPLE:  THIS NEEDS ATTENTION!!  HELLO??

    This will fix your drops:

    Unzip, then unzip the Kext Utility, then drop the kext on the Utility app. Supply your password, reboot and then hopefully all is well with your Wi-Fi connection.

    Hello you all,

     

    I also had the problem of a disconnecting wifi while my imac was sleeping. I did not have the reconnecting issue after sleep, but the lost connection issue during sleep which made it impossible to reach my imac for things like homesharing, apple tv or remote desktop. I have a late 2012 iMac with a clean ML 10.8.2 on it and wirelessly connected to an apple time capsule (same as an airport extreme). My partner has a mid 2007 iMac, also with an ML 10.8.2 on it.

     

    I tried every single solution I could find on the internet, such as changing the router's security from wpa2 to wpa, changing the MTU from automatic to manual 1453, router reboots, re-installations, re-configurations, keychain clean-ups, everything.

     

    Eventually I solved my problem with these steps and now it works as a charm. I can still find the iMac with the remote app, even after 12 hours of sleep:

     

    My time capsule router is set on automatic MTU and encrypted with WPA2 and I use  the 5Ghz network!

    1. Cleaned all the wifi passwords in keychain on my iMac

    2. Created a new network location in system preferences

    3. In this location I deleted the bluetooth pan and bluetooth dun connection.

    4. In this location I changed the preferred connection-order to wifi on #1 and ethernet on #2.

    5. Restarted my iMac.

     

    Now I still have a connection when it sleeps and I can wake it to low profile using the remote app (homesharing) and everything works fine.

     

    Hope more people wille be helped by this.
