AN-220-RT ARAKNIS NETWORKS 220 SERIES SINGLE WAN MULTI GIGABIT VPN ROUTER

I AM A RESIDENTIAL CUSTOMER OF XFINITY WITH A 5 YEAR OLD MODEM/ROUTER. IT WAS RECOMMENDED THAT I UPGRADE TO THE ABOVE MODEM/ROUTER.  NOT CONSIDERING THE COST, IS THIS COMPATIBLE/WILL IT BE SUPPORTED AS A RESIDENTIAL CUSTOMER OF XFINITY?  NEEDLESS TO SAY, I COULD NOT GET A STRAIGHT ANSWER FROM THE TECHINCAL EXPERT WITH WHOM I SPOKE. SHE WOULD ONLY REFER ME TO THE COMPATIBLE EQUIPMENT THAT XFINITY RECOMMENDS/SUPPORTS FOR RESIDENTIAL CUSTOMERS.

WHEN I EXPLAINED THAT THIS EQUIPMENT IS MAINLY USED IN COMMERCIAL/BUSINESS SETTINGS, AND ASKED TO BE CONNECTED WITH A REPRESENTATIVE FROM THAT AREA OF THE COMPANY, SHE SAID SHE COULD NOT DO SO.  SHE RECOMMENDED THAT I RENT THE MODEM/ROUTER THAT COMCAST XFINITY OFFERS TO RESIDENTIAL CLIENTS.

IS THERE SOMEONE WITH KNOWLEDGE OF THE EQUIPMENT I PLAN TO ACQUIRE WHO CAN GIVE ME AN ASSESSMENT?  THANK YOU.
