    Hey I am using Windows right now. I never realized this but my download speed is supposed to be 768 Kbps. Though when I download something my speed is between 70 - 90 Kbps. Is this normal? I ran many virus scans and I am clean.

    Is there something that is slowing it down? I am also using wireless connection.

    Heres the link to my plan:

    Thanks

    How are you measuring your speed?

    Are you sure you aren't seeing 70-90kB/s? AT&T quotes bits per second. If you're using Activity Monitor, that shows bytes per second.

    edit:
    The 768kbps also doesn't take into account overhead (roughly 10-13%). So, you divide by 8 (to get bytes) then take that overhead figure off. That comes out to: 83.53kBps

    You are confusing kilobits and kilobytes. When AT&T says 768kbps, they are saying kiloBITS. When you download something, its usually read in KiloBYTES. To convert, just divide the number by 8 (there are 8 bits in a byte). So in your case, 768 / 8 = 96. Thats the maximum your DSL line supports for download in kiloBYTES, with about 5% chopped off for overhead. In other words, your connection is fine.

    70-90 KB/sec = 768 kbits/sec

    If you are using wireless you might also want to think about using Open DNS or some other Domain Name Server besides the standard that ATT gives you. In my experience, the ones that are pre-configured suck, and I noticed a big difference once I started using Open DNS.
