I have Toshiba laptop (Satellite U505-S2925BN), upgraded from vista to Win7, every thing is working fine except when I checked the drivers on the device manager I found a question mark under other devices and when I open it I found 4 drivers missing: Base system Device (2 times), Network Controller, and unknown device.
I also noticed that my wireless is not working it is not detecting my router and I can not connect to internet any more. When I click on the question mark I got this message "The drivers for this device are not installed (Code 28)"
I have tried to find these drivers on Toshiba site with no help. All drivers are available except this one...please help
