It could have a bad connection to the wifi antennas in your laptop. Other things is someone in the area could be using the same wifi channels as you and causing interference. Inssider is a program that can show you if this is happening. https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&sqi=2&ved=0ahUKEwj18deEsLzKAhVGr4MKHdElCr8QFggcMAA&url=http%3A%2F%2Fwww.techspot.com%2Fdownloads%2F5936-inssider.html&usg=AFQjCNGg6RLozhNVKdAsUoKljfOx4e8Nqg&sig2=OXeNr_jDAIS9yb8GQAjS2g&bvm=bv.112064104,d.amc
