I just built a skylake and installed a Gigabyte GC‑WB867D‑I pci-e card. It keeps dropping the WiFi connection every few minutes and will automatically reconnect. I've tried uninstalling and updating drivers (using drivers from gigabyte's site), changing power settings in device manager. My other devices are not experiencing this issue. I've also checked my router settings and changed the channels, made sure it was on 2.4/5 mixed mode. Thank you for any advice and help you can offer!
