Unlimited data on VZW, can I tether to my router?

I can already do it via PDA Net (or FoxFi) via a USB connection or wirelessly if I use a pin lock instead of knock code... but what about hooking directly to my router.

I have an ASUS RT-AC66U (AC66R) router and it says it supports tethering via an Android phone:



Any ideas if I could get it working?
