I understand that the RPM file iwl7265-firmware-184.108.40.206-36.el7.noarch which provides the Intel microcode release version 9 on the AC-7265 NIC which comes with the Intel NUC5i7RYH, does not work with 5Ghz reception, so just use 2.4Ghz instead until it’s fixed. I will confirm this when the update has been released or you can experiment by using the older microcode release.
Here’s how I got my NIC working. I would like to hear if this helped you to configure yours.
