Two internet connections, but no internet connection

Just went through the same thing on my system -- disabling and reenabling the network interface will correct it until the next boot --- Found out it is a problem with a program from Apple that interferes with the loading if it runs prior to your network being connected ( it is a part of the Bonjour service included in I-tunes and Photoshop CS)- It started on my system shortly after reinstalling Photoshop CS -- To fix the problem you need to go into the system and change the service to a delayed startup (this makes the service wait a couple minutes before launching and gets rid of the conflict so your network will connect properly and the service will still launch properly.

To Set it to delayed press the windows key and R to bring up the Run box and type in Services.msc and press enter (Or type services.msc in the start box and select the services program it lists) -- this will open the Services box in that list find ##Id_String2.6844F930_1628_4223_B5CC_5BB94B879762## (it is usually the top of the list ) - highlight it and right click - select Properties -- this will bring up a new properties box - about in the middle you will see a drop down box to select the Startup type in it select Automatic (Delayed Startup) -- press APPLY and OK - close the Services boxes and restart your system (things will now work properly since your network adapter will connect to the internet before that service launches so the problem will no longer happen !!)
