    after sucessfully installing Vista on my computer i noticed that internet
    connection is acting weird.

    current setup is
    medium lan network (20 workstations)
    Cisco 831 Router
    D-link 24 port switch
    Broadcom NetXtreme Gigabit ethernet NIC

    my LAN access and things are working propertlly, but all internet activities
    run extremly slow and after some time it times out.
    for example when i start IE it normally opens live search page (which is set
    as default), but if i try to open it connects to the
    server, starts downloading the site and after maybe 2-3 seconds it stops
    loading (IE still shows as it is downloading web site). Basicaly what i get
    is only downloaded first few images and things from the website and it
    This happenes to all websites that have more content then google or live
    search websites.

    This isn't only IE problem it's all other applications. For instance, i
    tried to download newsgroups into windows mail. It starts downloading
    available newsgroups.. it downloads 27 of them then it takes few seconds to
    get few more and at some point it stops and i get timed out message asking
    if i want to wait or stop... waiting doesn't help since it comes up again in
    a minute.

    So this brings me to one conclusion that all my internet activities are
    suspended after i receive first few kb of data from the internet (at least
    from that host) or something like that.

    I tried following solutions (with no luck of getting to work):
    tried disabling IPv6
    tried disabling Link-Layer
    tried "netsh int tcp set global autotuninglevel=disabled" command
    tried reinstalling drivers for my NIC

    I'm seeing the same problem here. I'm testing Vista on my work network, and
    normal LAN related activities are fast and normal, but any internet is
    extremely slow or times out. Here's the interesting part, we have 2 networks
    at work, one for employees, and an isolated network for guest access to the
    internet, which is also still behind a NAT firewall. When I attach the Vista
    loaded PC to the Guest network, all internet activity is fast as it should
    be, but when I switch it to our internal LAN, the internet is non-existent at

    Any ideas?

    ok i found a solution

    right-click on cmd.exe
    select to run it as administrator
    and execute this command "netsh int tcp set global autotuninglevel=disabled"
    without quotes ofcorse.

    that helped me sort it out.

    are you running any type of web caching at work, I have the same problem
    with websites that are cached on port 80. if i connect to a non cached
    website (ie 443) i have speedy response. not sure why vista has this
    problem. I have IE7 running on a XP machine wih no problem. I will conduc
    some packet captures from XP and Vista to ascertain any differences in data
