RAX200 Multi WAN with two separate internet providers

[jaredaka007]

Does the RAX200 support aggrigation using both ATT and Xfinity?  I have a Nighthawk modem CM1200 and the routher above with ATT newly provided modem.  Can i link aggrigate both together?  If so how because the port aggrigation in the routher does not work it takes down the network...something is missing?

These consumer routers are not Multi-WAN models. The aggregation feature is pure L2 for bonding modems with services >1Gb/s over two GbE links.
