Hi guys, I recently bought an ipod touch 4G just so that I could facetime with the family back home when I travel. I installed facetime on my imac at home, and have it all set up properly. Tested it at home and it worked flawlessly. When I'm at a wifi hotspot however, facetime doesn't work as it should. The audio constantly cuts out, meaning I only hear the other side for a second or two, and then silence for 10-15 seconds. Repeat and rinse. Meanwhile the video is still flawlessly smooth. And the people on the imac hear and see me perfectly fine. I'm sure there is nothing wrong with my imac microphone since skype calls work fine. This happens consistently across all wifi hotspots. I have not made a successful facetime call yet to the imac at home. At first I just assumed that the wifi hotspot was slow, but then why would the video be working perfectly but not audio? Is there any setting on facetime where I can set priority to audio instead of video in case of a slow connection?
