AirPort is connected but no internet
Help please. All the sudden, I have no internet connection using AirPort extreme (1st gen). When I connect directly (without AirPort), I have a connection so my provider said it's the AirPort. My AirPort is working for music share, so I don't know what is the problem. I have tried hard reset, unplugging over night, restart... nothing works. Any help is appreciated. Thanks. Having said that, I also have an AirPort Express which is connected to play music so I can't say my AE is working??
