If you are a MagicJack user who's experiencing that constant bad phone connection where you just can't decipher or make sense of what the recipient on the other line is saying, well, I found the solution!!! It has to do with your network card not being optimized. I know, what does that have to do with MagicJack as it's plugged into your USB. The answer, your PC is not not utilizing your full Internet connection messing your VOIP connection. It worked great on my windows XP, and now my MagicJack works awesome!
