    ok. specs first. I'm running an XP Pro box with a 9800Pro vid card and a 3Com 10/100 NIC. I'm running a router (Linksys BEFX41) as a hardware firewall. My Son's PC is the only other pc hooked up to the router. He's running win98SE, GeForce4 Ti4200 vidcard and a Netgear 10/100 NIC.

    Here's the problem: When I go do a performance test at toast.net and download the same graphic file from the same location my first 3 runs were:

    1910 Kb
    1927 Kb
    2058 Kb


    When I do the same test, same graphic file, same location, my Son's PC does:

    520 Kb
    538 Kb
    543 Kb

    ??????????

    I don't understand, shouldn't he be pulling the same, or similar, download speeds as I am??

    When I ping an IP from both PC's we get almost identical pings. I know latency and download speeds are 2 different animals, I just put the ping comment in to show that there weren't any latency issues.

    any ideas????

    AZ-Boog - The default setting for the "TCP Receive Window" in Windows 98 is way too low for broadband.

    I would download Dr. TCP from DSL Reports and set "TCP Receive Window" way up.

    The default is 8192 or 16384, try it at 32768 or 65536, etc.

    This usually makes a dramatic difference for broadband users on Windows 98 (and Windows XP also, IIRC).

    Here's some more reading, if you want it: HERE and HERE

    Hope this helps !

    There's the kinda help I was looking for. Thanks sdakota. I'll give it a try.

    Is there a way to set this in win98 without resorting to a third party utility?????

    Yes, if you are comfortable editing the registry.

    First, back up the registry.

    Navigate to [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MSTCP]
    and create/alter a key named "DefaultRcvWindow" with a value of "65535", or whatever value you want to try.

    That should do it.
    Best of luck !

    PS> I got this info from http://cable-dsl.home.att.net/
    I don't know why they use 65535 instead of 65536.

    Thanks for the help.

    Because 2 ^ 16 = 65536, but you have to count zero too.

    set it to 65535 and jumped to 1883Kb for the graphic download from toast.net.

    excellent!

    thanks for the help all, and especially sdakota!
