Using the windows 10 supplied driver for the intel pro 3945abg wireless card on my dell laptop, often results in an inability to connect after a start or restart. when this happens, i disable the network card via device manager and then re-enable the network card.. I have an old acer aspire 5920 (32-bit) laptop with an intel pro/wireless 3945abg adapter. i just forced it to upgrade from windows 7 to windows 10, i noticed straight away that the wireless was not working.. Use the links on this page to download the latest version of intel(r) pro/wireless 3945abg network connection drivers. all drivers available for download have been scanned by antivirus program..
