you're out of luck to the best of my knowledge.
There are no LEAP or EAP-FAST supplicants available for the N700 or N800 that I'm aware of.

Best is to hope that an EAP-FAST supplicant is released, but I've heard nothing indicating that any are in development

My work uses EAP-FAST. I either have to use the guest WLAN access, or my phone
