I have had problems with the wireless connection too on a Toshiba satellite laptop due to the Atheros network adaptor being incompatible with the computer. Check with Atheros for an updated driver. Note to everyone, before downloading windows 10 - 1) check on your computer manufacturers website to ensure your computer is compatible with windows 10, 2) check that any software e.g picture editing, etc is also compatible with windows 10 and 3) back up everything on your computer - operating system, software and files - before downloading just in case!
