I use video ichat quite a bit with family and friends. Most of the time when i use it everything works great but when i try to talk to my dad it will work for a couple of minutes then it gets really bad static. Sometimes after a few minutes the static goes away and it is fine after that, but sometimes it does not. While there is all this static my dad can usually still hear me but i cant hear anything. Anybody have any suggestions on what may be causing this?
