This is a posting for others seeking confirmation. When trying to upgrade my DC3217IYE to Wifi AC using the 7260.HMWG.R on a Linux Mint distro, the unit freezes repeatedly.
If I revert to the previously installed Ultimate-N 6300 (rev 3e) the unit performs normally. Additional info:
BIOS: v. 0055
NUC: DC3217IYE
Linux Kernel: all tested, including 3.16.0-29
