My router blocks FaceTime port/protocol?
I have NVG510 at home with ATT internet service. And FaceTime on iPod/iPad is my lifeline to contact my families/friends. It worked pretty well until very recently.
But all of sudden, it stopped working at home. It always fails to establish connection, even though I can hear the ringtone. When I faced the issue first time, I thought the service is down or my device is in trouble. But that's not true, because FaceTime still works when I brihg my devices outside, like to my office. Now I assume that my router blocks port or protocol used by FaceTime. But I did not change any settings on my router.
So I had a chat session with ATT support, but I did not get any useful information. The service rep just told me that higher level support is requried.
Does anyone have a clue to slove the issue? FaceTime is really importnt to me. I have to consider to switch provider if it's not available via ATT internet service anymore.
