Network bridge on XP kills wireless transfer rate.

    I have an ad-hoc 54g wireless LAN setup using a Belkin PCI (Win XP
    Pro) and a Belkin notebook (Win2000) card - no access point. The
    desktop PCI card is installed in my wired LAN ICS machine.

    When the ad-hoc network link is running unbridged peer to peer, the
    transfer rate is lightning fast and the rate doesn't drop from 54Mbps
    with each PC having excellent signals. Great for file transfers - but
    I can't browse the Web so......

    I bridged the wired lan to the wireless lan as per the instructions on
    the Microsoft website and now when the two machines talk to each other
    the transfer rate drops to 1Mbps and becomes practically unuseable.

    Any suggestions as to why the bridge seems to be killing the wireless
    connection or how can I improve the rate?
    Is it the bridge that is causing the problem?

    Many thanks in advance.

    I have been trying the same thing today but with two Belkin PCI cards and
    had the same problem re: speeds going down to 1MB (though I don't have an
    existing network)

    Having just got off their 24/7 freephone number, they said that I should
    update to the latest drivers and then go to Device Manager in each machine
    and under the Belkin Kit, go to the Advanced tab and choose "54g-
    Performance" under IBSS 54g mode. - that solved the speed issues for me.

    They also told me I shoudn't use the bridge option in Windows XP as it
    wasn't the "correct" thing to do but should use ICS to connect two machines
    together - though they don't officially support ICS... (so I have to figure
    out how to do it- any ideas? (particularly re: IP addresses)) - still at
    least they helped me to get my machines to see each other at a decent

  3. I got rid of the bridge and used ICS with some help from the following
    Hope this helps,

    Just to follow up - I may have a solution.

    It seems that ICS creates a bridge when you set it up and I found my speeds
    were dropping down to 1MB(again) as well whenever I browsed the internet as

    My solution is as follows.

    1. Download the US version of the drivers on both machines
    2. Uninstall the EU version of the drivers
    3. Install the US drivers - choosing "Worldwide" under the country settings
    in the Belkin utility - I have yet to experiment with the other country
    settings offered
    4. Change the device manager settings to "54g-Performance" under IBSS 54g
    5. Install Internet Connection Sharing... etc

    This has worked for me - I am able to connect via my 2nd PC at 48/54Mbs and
    connect to the internet...

    If it works for you, could you let both me and Belkin
    () know - I am just going to email them myself and ask
    them to fix the European drivers - they have only just released the latest
    US versions and the EU ones are currently dated from about 2/3 months ago so
    are hopefully due for an update soon..

    If it doesn't work I'd also like to know:)

    Hey Sunil,

    Thanks for the information. I had just downloaded the new US drivers
    and was about to try them anyway when I saw your note.
    I Went ahead and installed them and like you can get good transfer
    rate on both Net access and file transfer.

    The rate problem came back when I set up the bridge again which is a
    real pain. At least I know it is a driver problem now!
    I will just have to decide if I want wireless LAN access or keep
    switching the ICS connection between the wired and wireless LAN.

    I hope Belkin see sense and release drivers which will support the
    network bridge in future.

    Did your cards run at 54Mbps when connected to the network bridge?

    Make sure you have choosen 54g-Performance" under IBSS 54g mode on both
    cards - until I did this I found the speed used to drop.

    My two computers now seem to work fine(48/54Mbs) using ICS (which I believe
    creates a network bridge?) and an external USB modem.
