When I first start my computer, My WiFi and WiDi work fine. After using the computer for a while, or after waking it up from hibernation, WiDi says My WiFi is disabled, and to scan for adapters to enable. However, the scan doesn't work and the same message shows up at the end. The computer beeps and a notification shows up on the bottom-right of the screen saying My WiFi is disabled.
If I go into the My WiFi program and hit the Enable button, it goes gray for a few seconds, then back to the green Enable button. Again, I'm greeted by a beep and a notification box letting me know My WiFi is disabled. (Thanks, I already knew that! It must be mocking me.)
So neither of these methods work to enable My WiFi. I have the latest PROSet driver, the latest WiDi driver, etc.
My computer is a new Toshiba Satellite E305-1990x.
I got this info from another thread asking the same question; answer was from a user named Samantha, when I was having the same problem, and it worked perfectly for me and the original poster of the other thread that had our same problem as yours;
Here ya go.. checkitoutman;
Go to Control Panel>Programs(unstill a sprogram)>then find Intel (R) PROSet/Wireless WiFi Software.
Double click on it and wait or the wizard to let you click next. then click modify and next. Then on the dropdown click on Intel (R) My WiFi Technology. to the left of it you can click on a dropdown menu and then click on this feature will not be avavilable. Once you click next let it finish. Then go back and redo everythign and when you get to the dropdown menu click on This feature and all subfeatures will be installed on local hard drive. Then click next and once that completed you should be back in business.
Please let me know if this helps you as much as it seemed to help everyone else in the forum that wereall saying this worked for them as well as it worked for me. It sure fixed my same problem as yours right up!
