I have an Acer Aspire D270 with windows 7 32 bit installed. Also I have windows 8 installed. For 3 weeks both have been working just fine. One night I left the netbook on downloading in Windows 7, I woke up and then the "network controller" drivers are GONE! How could that happen? I found the drivers on the CD, tried to install them and it does not work.
"atheros ar5b125 wireless - no driver selected for the device" it encountered a problem.
When restarting the laptop and booting into Windows 8, the wifi works fine. So why is it not working in Windows 7 but in Windows 8 it is OK, what happened in my sleep to make the drivers disappear and not be able to install it again?
