I added a WiFi card to the Z170 today, which I ordered from NewEgg. GIGABYTE Model GC-WB867D-I (ver. 2) Bluetooth 4.0/WiFi Expansion Card Installation time took about three minutes and required plugging it into one of the three PCI slots and securing it with the thumb screw. After powering up the Maximus VIII and installing the included driver, plus restarting the Z170 the wireless portion hooked right up to the Internet. Not thrilled with that 30 to 35 degree Celsius temperature reading though. My contact in Louisiana, tells me that’s about normal for the liquid cooled systems.
