I installed Win 10P this evening and one of the drivers that were missing was for my NEW Z97X G3 MB with Killer E2200 LAN.
Don't know if this will be an issue with any other LAN driver but, I was a little dismayed that being a BRAND NEW M/B and
that this is not just a one of a kind LAN chip, that MS had forgotten this one?
Win 10 also doesn't install all INTEL chipset drivers either. Maybe someone else could post their experiences with Win 10 and LAN drivers?
So, if you have a M/B with this LAN chipset, go to Atheros Website and download their new drivers, much later than the ones from GB.
