I have the USBConnect 881 card. This is my 4th day with it. I am not satisfied with this so far. I have been getting 5 bars these 3 past days but today - 3 bars IN the same spot! Plus I have problems such as it connected but not going to webpages or very slow. It has been working great but now. Im on the Edge network but it has been going fast. What is the problem?
