why did my wlan adapter not work until windows 10 was installed?
I've tried running troubleshooting, taking the wifi card out and reseating it, reinstalling the drivers. I used an usb wlan adapter to get internet to the device and installed all drivers that I could (I couldn't get one of the chipset drivers to install) and as many windows updates as I could. After having windows 8.1 fully updated and nearly all of the drivers installed (included network drivers) the onboard wlan adapter still wasn't working.
I was convinced that the oem dell wlan adapter was broken until I did the final update to windows 10. this morning, after windows 10 was installed, the onboard wlan started to work again. any ideas what happened here?
