    Yuck, I think I made a mistake- help??

    Hello,
    I think I made a mistake. I live outside of Tampa and recentely switched over to ATT DSL from Brighthouse (cable). Now I'm getting less than I expected. I tried the optimizer but to no avail. Any help would be appreciated.

    Your MTU should be 1492. Log into your modem/router set MTU 1492, MSS 1452 then reboot and post new TCP Analyzer Report.
