Specs on RB2011UiAS-2HnD-In

Is the router RB2011UiAS-2HnD-IN 802.11n or 802.11ac or something else?
Also, what is the difference between the Gigabyte & Fast Ethernet ports?

Hi

Check it:

The first 5 ports and the SFP are 10/100/1000Mbps, the last 5 ports are only 10/100Mbps. Check the block diagramm to see the speed between this port groups.
