    I have Xfinity 1gbps; I am only receiving 45% of my speed

    When I first got the upgrade it was 1.3gbps now I have 450mbps. It's very annoying. I have tried TCP Optimizer from The program for tweaking your settings has worked in the past. However, now, it doesn't surpass 100mbps+; when it originally went up to 1gbps.
