    Extremely slow dwnload speeds with Roadrunner

    Just as the title says, I'm getting extremely slow download speeds (around 88kb/s) with my new ISP. A friend of mine has Roadrunner as well, and get's anywhere from 500 to 750 kb/s, and he lives only a few blocks away. I'm not very technical, so I do not know my max bandwidth and the like, but I know that 88 is WAY slower than it should be. If anyone could tell me how to check my max bandwidth and any other important information, I would be EXTREMELY thankful.

    Thanks trogers, I've been looking all over this board for help and you seem to know what your talking about, lol. Unfortunately, I don't think what you said has changed anything.
