A:Answer You wont be able to aggregate ports directly to this modem, as it only has 1 port for Ethernet on the back of it. I too have aggregated ports connected to a switch. Therefore the modem does use aggregation, but your main router which connects to it should be set to static lag on the 2 1 gb ports, then the switch has to also support port aggregation as well in order to work. You cant use the router without a smart managed switch that supports the aggregation.
