I can't find an official bandwidth for the router, it's an AT&T BGW320-500 which from what I could find online others have said it is supposed to support up to 10Gbps internet speeds. My current 8 port switch has a 1.6Gbps capacity and I decided to go ahead and get an 11 port gigabit switch that has 12Gbps capacity. I've been putting off getting a new switch for awhile so it was time.
