My wifi just died today and I have been trouble shooting for a while. When I'm in Device Manager and I click on scan for hardware changes it shows the wireless controller. It does not list any information when I click on the properties for the controller. It find any drivers to install for it when I pick install from computer or find on the internet. I have gone to the Toshiba drivers site and downloaded all of the wireless drivers listed for that model. Nothing is working. Any ideas? Thanks for you time.
