The onboard wifi was working the night before with no issues. Booted up when i got home and there are no connections listed. I uninstalled/reinstalled the drivers but that has no effect. I even restored the system drive with acronis to a week before. I tried clearing cmos and disabling/enabling in bios to no avail. Device manager shows no prblems with drivers. Windows diagnostic reports a problem with adapter but doesn't help much beyond that. It's almost like the wifi radio died all the sudden. I had to put in an old netgear usb adapter and it works fine. I'm not sure what else to do to troubleshoot it.
