Windows could not find a driver for your network adapter" i have checked in device manager and there is no network adapter. i am using windows 7 home premium 64bit.. Point to the inf file in the driver folder, and then click open. note: please click start button, right click computer and go to properties to confirm operating system and system type of your computer.. If the network adapter driver is outdated, corrupted, broken, damaged, missing or incompatible with your windows 7, you will encounter network issues, such as you have no internet connection, can’t share wifi internet connection, connected to the internet but have no internet access, the pc freezes when you try to access the internet via wireless adapter, network adapter is not detected, etc..
