We also have seen a huge rise in issues. 10.10.3 which is being tested
right now seems better, but not a solution. Here is some of what we tell
folks who have issues. The firts set removes all network settings, but
seems to help the most.
*REMOVE MACHINE NETWORKING PREFERENCES*
1. Click on the WiFi icon in the top menu bar and select: *Turn Wi-Fi
Off*.
2. Click anywhere on the desktop.
3. Click on *Go* on the top of your screen.
4. Choose *Computer*
5. Choose your hard drive (it may be named "Macintosh HD")
6. Choose *Library*
7. Choose *Preferences*
8. Choose *SystemConfiguration*
9. If the following items exist in the SystemConfiguration folder, drag
them to the trash. (Note: They may not all exist.)
com.apple.airport.preferences.plist
com.apple.eapolclient.plist
com.apple.network.eapolclient.configuration.plist
com.apple.network.identification.plist
com.apple.wifi.message-tracer.plist
NetworkInterfaces.plist
preferences.plist
10. Restart your computer.
*NOTE: *After doing this step, you will need to rejoin any WiFi networks
you have at home, etc.
*ADJUST WIFI NETWORK WAKE SETTINGS*
1. Open the *Energy Saver* system preferences (It can be found at *Apple
Menu > System Preferences... > Energy Saver*)
2. If using a Macintosh laptop, click on the *Power Adapter* button.
3. Uncheck *Wake for Wi-Fi network access*.
*ADJUST AIRDROP SETTINGS* (NOTE: This step is only for newer Macs having
the awdl0 interface)
1. In the bottom dock, click on the *Finder* icon.
2. In the Finder window that appears, on the left side click on *AirDrop*
.
3. Look at the bottom of the right side of the AirDrop window.
4. Look for the pulldown labeled: *Allow me to be discovered by*
5. If the pulldown is there, select *No One*.
*NOTE*: If the pulldown is not at the bottom of the AirDrop window, your
machine does not have the awdl0 interface. You can skip this step.
*TURN OFF IPv6 NETWORKING*
1. Open the *Terminal* application. (It can be found at *Applications >
Utilities > Terminal*)
2. Type the following command: networksetup -setv6off Wi-Fi
3. Hit return on the keyboard. (You won't see any visible change, but
the command has been executed.)
4. Close the Terminal window.
