Moving into a new house, improving the internet

I want to go with the TL-ER7206 router, but Quantum fiber internet says the router must support the following:

•1 Gps Ethernet WAN port (obviously yes)

These I dont know

•Ethernet 802.1ad VLAN tagging on the WAN
•DHCP with CHAP authentication on the WAN
•LCP Echo responses

Any idea on how I find out if this will be a compatible router?

Thanks for the replies
