    WinXP wireless problem...

    I've been trying, off and on, to troubleshoot this annoyance for a
    while but haven't been successful.

    My computers connect to a wireless AP that is attached to a wired
    router. The router provides all DHCP.

    Every time I logon to WinXP, the connection "breaks". It doesn't
    "break" right away, but about a minute after logging in. I believe it
    is likely a DHCP issue.

    I know for certain that the problem lays somewhere in Windows and not
    my network hardware because my other computers running Linux don't
    "break" their network connections.

    This is a clean WinXP computer. There is no junk installed and I'm
    very meticulous about what processes are allowed to run.

    I don't know what else to check in Windows.

    Any ideas?

    Thanks.

    Oh, the way that I re-establish the network connection is simply by
    bringing up the DLink client and re-connecting to the AP. The
    connection will continue to run, even after logging out, until the
    next time I logon to WinXP. Its as if there is a process in the
    startup breaking the connection. This is a perfectly clean and fresh
    WinXP install.

    It would probably be useful to know the make and model of your router,
    the make and model of the working and nonworking wireless hardware, the
    versions of windows and Linux etc etc.

    Most likely issues - interference which the windows box is more
    sensitive to because of its physical location, powersaving enabled on
    the network device, bugs in the windows driver software.

    Re: WinXP wireless problem...

    The WinXP computer is in the same room as one of the Linux computers.
    Signal strength is a steady 85%
    All drivers are current.

    I just tried using a static IP, but had the same results (connectivity
    lost after each login). I still have to manually "bump" (re-connect)
    the connection after logging in, even though the tray icon doesn't
    show the connection as lost.. This seems to suggest that it isn't
    DHCP, but something else going on.

    Anyone familiar with WinXP enough to know what exactly it does with
    network connections at each login? Something is causing it to get
    lost. This is a clean and fresh WinXP install, so it must be
    something in Windows.

    Install XP SP2. XP had a problem sometimes dropping connections that SP2
    normally fixes...
    (The XP WZC service is by default configured to enable 802.1 x
    authentications. This
    authentication process would often cause the system to drop the wireless
    connection
    about every three to five minutes.)
    To avoid this problem 802.1x authentication should be disabled.
    If you want to do it without installing sp2 :
    Click Start, point to Connect To, Click Show all connections, and then
    double-click your wireless network.
    On the General tab, click Properties.
    Click the Wireless Networks tab.
    Under Preferred Network, click your network and then click Properties.
    Click the Authentication tab, and then clear the Enable IEEE 802.1x
    authentication for this network check box.
    ( http://www.sydneywireless.com/?p=777 )
    or
    If you changed or upgraded your firewall software or anti-virus software,
    try disabling it.
    The Windows firewall may be on without you being aware. Disable the Windows
    firewall.
    Update the Router firmware?
    Make sure that EACH PC has a unique IP address?
    or
    Connect all bar the XP machine, make sure all is ok, then connect the XP
    box. As soon as it connects, 'repair' the connection on the XP machine, or
    use winipcfg or ipconfig to perform a manual DHCP release and renew...
    If you are using 128-bit WEP, try using a 64-bit key instead. Depending upon
    your hardware, there could be an interoperability problem between the wifi
    modules you are connecting through.
    Turn on MAC address filtering in the router?

    There, something must do the job from that list!

    Yep, but you didn't bother to supply any makers, models, or numbers,
    of your hardware, so I can't really offer specific suggestions.

    The easiest way to determine the cause of failure is to enable
    Wireless Zero Config logging.
    <http://www.microsoft.com/technet/network/wifi/wlansupp.mspx>
    It's quite an ordeal slogging through the voluminous logs produced by
    WZC, but the answer should be in there somewhere.

    However, before you embark on that adventure, you may have a point
    about DHCP.
    Start -> run -> cmd <enter>
    ipconfig
    What do you get before and after you "login".

    Wow, thanks!

    Your reply is leading me very close to the fix. I forgot all about
    WZC as I had been using the DLink client. Using WZC, everything works
    like it should. I don't have to "bump" the connection after logging
    on.
    So... It looks like it must be with the DLink drivers and client.
    I'll try weeding that out now. Before tinkering with the DLink stuff,
    I have a new suspicion first. I just noticed in Device Manager that
    the wireless card is mislabeled as "Wireless PCI Adapter #2" even
    though there is just one card installed. I now remember Windoze
    mislabling another piece of hardware (soundcard) once as a "#2" and it
    caused some weird problems. I'll try deleting it and rebooting.

    Thanks!

    Ok. Got that fixed.

    It was the same issue as with the soundcard, multiple entries in
    Device Manager!

    For future reference (probably mine!), to get to "unconnected" and
    unused entries:

    cmd
    set devmgr_show_nonpresent_devices=1
    start devmgmt.msc
    (Show hidden devices on the View)
    (Delete the ghosts)

    F'n Windoze!

    Thanks!

    At some point, probably due to drivers, the card appeared different 'enough'
    for the OS to treat it as such.

    Since you don't mention what sort of network interface it's not possible to
    pinpoint why. But a device moved to a different USB port, or card slot
    would definitely do it. Combine that with screwing around with drivers and
    it'll certainly happen.

    An OS or driver update also does it, sometimes. I just finished
    setting up XP SP1 on a Compaq V6000 laptop with a built in Broadcom
    wireless card, using the original HP recovery CD set. After initial
    installation, it would connect nicely using wireless. Of course, any
    recovery CD that's older than 30 seconds requires hundreds of
    megabloats of updates for everything. After multiple rounds of
    updates for the OS, apps, drivers, and junkware, it now connects using
    "wireless something #2". Apparently, this happened during an update
    of either WZC or the Broadcom drivers. No hardware juggling or
    screwing around required.

    Hmmm.... You gave me an idea. The machine I'm using and one of my
    laptops are also my test machines, where I plug in random wireless
    devices, check if they work, and then either put them back in the box,
    or deliver to a customer. If the device came with an
    insallation/uninstallation program, I would usually uninstall the
    driver.

    So, I go unto:
    Rt Clik on My Computah -> Properties -> Hardware -> Device Manager
    and
    View -> show hidden devices
    (This is the same as your command line incantations)

    It was showing a huge number of ancient devices and duplicates, many
    of which are long gone. Some of the duplicates are obvious entries
    for the same device, walking through multiple USB ports. My printer
    collection is also a mess for similar reasons. Equally irritating
    are entries from mulitiple anti-virus products and multiple AVG
    versions. What a mess.

    Are you sure the initial connection is real and working? Windows XP has
    a problem in that it can report an initial connection that doeesn't
    actually exist, which then seems to later break.

    I haven't fully verified this, but one way it seems to happen is when
    Windows XP is shut down or put to sleep or hibernation. Then when
    Windows XP wakes up it thinks it's still got a working DHCP lease, but
    that lease has been idled out by the wireless access point. Eventually
    Windows XP figures out that it doesn't actually have a connection.

    Try disconnecting from the wireless before shutting down, sleeping, or
    hibernating, and see if that affects the problem when Windows XP start
    back up.

    Also check your logs to see if some error is being logged when this
    happens.

    I am having a similar problem with WinXP.
    I have two Compaq laptops, both with built-in Broadcom wireless hardware, both with updated drivers. One has WinXP Home, the other Vista Home premium.

    The Network uses a D-Link DWL-G710 range extender with a D-Link DIR-655 router. The extender is over 100 feet from the router, in another building, so interference may be a factor.

    Both laptops can connect to the extender, but the Vista system performs much better than the XP system - packet loss around 5% for Vista vs 30 to 40% for XP. The Vista laptop can downoad at the full 1.5 mbps speed of the network's T1 line, the XP system only manages 400 to 500 mbps. And the XP laptop has to be in the same room as the extender, the vista system works fine one room away.

    I've tried using TCp Optimizer on the XP laptop but no improvement. I just got a Buffalo AirStation High Power pci card to see if the laptop's hardware is the problem, but the Buffalo card won't connect to the extender at all. If interference is the problem, why more so with the XP system? Any ideas?
