ok so i got this same problem too and the reason is simple you need only to configure your internet conenction as primiry connection i give a exemple if you have internet wire + internet wireless + bluetooth connection installed on pc you need to change priority given the first one to the one yu use either wire or wireless this change can be made in configuration panel , share and connection , , modify card configuration , there you see alll your connection available (for me 3 ) , you press ALT , choose advanced , advanced configuration , here in the first tab you see all your configuration priority make teh one you use in the top with arrow here you go hope it is ok now i thought it is mac problem or xuid but this trick solve it so try and give me a feed back
