I'm running WIn 10 and within Device Manger it shows I'm running driver version 184.108.40.206 3/21/2017. The Intel Driver Update Utility confirms this version and tells me there is a 22.6 version available. So I use the utility to download that version and install it. Unfortunately something is wrong as my installed version continues to show 220.127.116.11. I extracted the ZIP file that the updated drivers are in and looked at the .sys file that is loading (e1d65x64.sys). It shows 18.104.22.168 as the version and not 22.6. So I'm confused where the 22.6 is coming from.
22.6 is the version of the overall driver package. It contains multiple versions of the drivers for the different MAC & PHY hardware. This is why the version numbers differ. Just install the package and don't worry about the version number you then see...
Hope this helps,
