We thought at first that Goofy had stepped on the wi-fi button, but later learned that HP laptops tend to have disconnects possibly due to overheating from video cards. The fan on this one is extremely quiet. I suspect heat buildup from leaving the laptop on for a couple of days, caused the problem. It also causes the volume control to pop up constantly. A web search showed that many people have had this problem with HP laptops. Other than these two problems, we really love it.
