I Have a newbie question. I purchased a TP-link TX201 network card. It is rated for speeds up to 2500 Mbps. Is this a true multigig port that will handle any speed up to 2.5 Gbps. I other words my internet plan is 1.4 Gbps, will the tx201 achieve something close to this speed or since 1.4 Gbps is below the 2.5Gbps step, will it revert to 1.0 Gbps?
