Okay, I have thought of this multiple times. The DGl 4500 has a gigabit lan port and a gigabit wan port. Which in terms mean its able to go up to 1Gbps, but if you have 4 lan ports can they all go up to 1Gbps? The answer is most likely no. So that means this router is only capable of doing 250Mbs on each gigabit lan port. 1Gb divided by 4 lan ports is 250. Anyway this is a theory I have, care to tell me what you guys think? I will start a thread soon on this matter with more information that I have gathered.
