Why is XP VPN client limited to 28kbs?

    I'm on a broadband link with a 1mbs upload speed, but I can't get faster
    that 28kbs. How do I increase the link speed?

    Have you contacted your broadband provider? That would probably be a good
    first step.

    What's on the other end of the VPN tunnel?

    Sometimes it initially connects at 28kb
    and throttles up...
    Does it?
    if not try setting the MTU on the receiving end to 1400 or 1300
    if still no
    please post back with router(s) models network details

    provider supplies 1mb upload speed to client, 6 mbs download. Server
    provides 10 mbs down, 1 mbs up. The peoblem is with the client, I believe.

    When I did some work at home with a VPN tunnel (third party software),
    they blamed bad performance on a mismatch between the MTU of the VPN tunnel,
    versus the MTU of the computer. The resulting packet fragmentation
    was supposed to be what was reducing my file sharing speed to
    4KB/sec. I was too busy at the time, to fix it. It is pretty funny
    to be using ADSL, and see dialup performance :) Fortunately, other
    protocols were more tolerant of the mess, so the VPN wasn't a total
    loss. I could still get some work done.

    Other point, check the port you are using (at the server end) isn't being
    affected by traffic-shaping measures at the client ISP. If it is, use of a
    different port may be a solution.

    MTU is set at receiving end to 1493.

    Current Server: 2003 server
    Router is 2wire, 2701HG-B Gateway
    8 Ethernet, 0 Wireless, 100 BaseT

    Alternate vpn authenticator is Window XP Pro, used for testing

    It doesn't matter which server/alternate used, connncection is 28kbs.

    I have access to other corporate networks, using Linksys/Cisco, SMC, and
    Efficient Networks routers, with same results. Problem occurs using XP
    wkstations on LANs using 2Wire, Linksys, and on wkstations using Verizon 3G
    USSB769 device, too.

    I'm convinced the issue relates to the default configuration of the XP
    client.
