A:Answer If you're using the port marked "Internet", it's limited to 1gig. The router supports WAN aggregation, but I'm assuming you have one link from your ISP. If that's the case, try configuring the 2.5Gig port as your WAN interface.
Second, all of the LAN connections are going to be 1Gig as well. This router does support LAN link aggregation if you use the two aggregate link ports, which would allow you to have 1Gig + 1Gig = 2Gig to the device. Some computers, especially gaming computers, have two LAN connections for this reason.
So, run your internet into the 2.5Gig port, and run two cables to your computer using the aggregate ports to get 1gig+1gig. At least that's how I understand it.
