This update corrupts the network settings. To recover, you need to delete the network plists and recreate your network settings.
Launch Terminal and type the following:
sudo rm /Library/Preferences/SystemConfiguration/NetworkPreferences.plist
sudo rm /Library/Preferences/SystemConfiguration/preferences.plist
Restart and recreate your network settings.
If that doesn't work, contact support@sonnettech.com. Be sure to save and send a System Report.
