    I think your problem is the version of tivo software you're running. 7.1 is the first version that supports USB2.0. If you upgrade the software you should see higher transfer rates (I think)

    The way I see it there are 2 ways of determining actual network transfer speeds.

    1.) When you start the transfer, not the specific date and time on your PC
    2.) monitor the transfer until it is complete
    3.) once the transfer is complete, look and the "date modified" of the resulting tivo file
    4.) subtract #1 from #3.

    To convert to KB/sec
    1.) convert the resulting time from #4 above to seconds.
    2.) Getr the file size of your tivo file in KB (bear in mind that Windows explorer generally displayes file sizes in KB, unless you are looking at the file properties, in which case they use MB, GB or bytes. Just keep in mind that ther are 1024 MB in 1 GB and 1024 KB in 1 MB and 8 bytes in 1 bit.
    3.) Do some math

    Post your results:
    Generally I see around 250-300 KB/sec over Wireless G.

    This just happens to be approximately I get if I were to download a file directly from TiVo's built in web server.

    This seems dog-slow, even for wireless.

    That said, go pick a large file at random to download from the internet. Even with a hot DSL connection, I tend to see download rates in the 250-300 KB/sec over Wireless G.

    I think that the problem is that TiVo's IP connection is limited to 1 stream, therefore you can't do the typical WebServer/Browser tricks like opening multiple connection streams.

    Any comments?

    Hello,

    I have TWO Tivo Series 2 units, both are hardwired into the Linksys Router "G"

    Would my speeds increase for transfer between Tivos if I swapped the Linksys to an "N" router - keeping in mind both will continue to be plugged into the router with cat 5

    Thanks.

    Nothing would change at all.

    USB 1.1 = 12 Mbps รท 8 (bits to a Byte) = 1.5 MBps
    (many of the posters in this thread pay no attention to upper or lowercase when it is a huge difference. M=mega m=milli, b=bits B=bytes)

    that said, I agree. AAAAAAAAAARGH!!!! I just bought the same damm adapter because it is on TiVo's approved list, not knowing that it was USB 1.1.

    Now I'm on the hunt for a USB200 or USB300. Neither of which say "HighSpeed" but only say USB 2.0. But my fingers are crossed that both are high speed - 480 Mbps.
    I think the jump from 12Mbps to 480Mbps would be quite tangible, right?
