New toshiba satilite laptop, windows vista, wireless to a router to a DSL line. When I start to download a file the download starts, you see the image of the files moving, the time left changes, and % increases, then at about from 3% to 7% it stops ,the image of the file download continues, but the time and % stay the same. It happens on all sites and all size files. The other computer on this network works great. Thanks in advance.
