Wireless Overhead Perhaps? (Score 1)

I to also have the same Comcast plan that you do. I have found that when I run a speed test on my laptop that is connected wirelessly I can typically only get DSLreports.com to report that my download is 2 to 3 meg a second. Now granted my access point is using WPA and when I take off WPA I do notice that my throughput increases substantially. This Wireless AP that I'm using is an enterprise class AP and so I can only imagine it being that much worse if you are using some retail equipment. I do also have a desktop that is hard wired into my network and when I run a speed test on it I usually typically do have it test out around where it is suppose to. So I don't know if you are in a situation where you are connecting via a wireless AP or not BUT connecting to your ISP via wireless does add considerable overhead and from my experience does cause connections to report as being slower then what they truly are.
