Windows 10 x64 no longer sees the Intel AC7256 wifi adapter in my Elitebook 850 G2. Device Manager says "Windows cannot load drivers for this device (Code 31)". The WiFi part of the adapter won't install, though it is listed with the yellow triangle in Device Manager, however, the bluetooth part is working fine. Ethernet also working fine.
Failed fix attempts include:
Event viewer suggests the first recorded error (18/9/22) as:
Device ROOT/NET/0000 had a problem starting
Driver Name: oem93.inf
I appreciate that there are no Windows 10 x64 HP oem drivers listed for this adapter, but it had been working fine for months until it suddenly disappeared in September. I'm suspecting a motherboard error or chipset driver issue, but any hints or ideas on where to go next for a fix appreciated.
