Cannot ping machines behind a wireless AP

    I have two XP Pro machines, both at Service Pack 2 (firewall turned off for
    testing)
    that can ping every machine on the LAN EXCEPT for machines that are
    connected using a wireless link between our office and factory...(via a
    wireless AP). The IP's of these machines at the factory are in the same IP
    address range as the office machines and have the same subnet etc... I am
    having no problems with any of the other XP machines on our LAN except for
    these two - and I can't seem to find where the issue lies with them.

    One is hard wired to the hub and the other is using a wireless card to
    connect to a WAP we have here in the office. However, on that machine, when
    you remove the wireless card, and plug it directly into the hub using hard
    wired ethernet, it can then see the other machines!!!

    Background...

    We have an office and a factory - separated by about 1 mile. The machines at
    the factory are connected to us using a wireless connection. We have a
    wireless radio at the office (IP is 192.168.2.250) and we have a wireless
    radio at the factory (IP is 192.168.2.251) - which is then plugged into a
    hub to provide access for the PC's at the factory. The two machines I am
    referring to above that I am having problems with can both ping the radio
    connected to the hub at the office (on the local LAN) - but can not ping
    anything (not even the radio) at the factory - 192.168.2.251??

    Very confusing indeed... At first I thought it was an issue with the
    wireless ethernet card on that users laptop but now that it is also
    happeneing to a different hard-wired machine - it must be a setting in the
    network connections area....

    Does anyone have any ideas what I should be checking??? Could it be
    something to do with the
    wireless radios that we are using as the link between factory and offices
    that could be causing a problem
    for the particular NICS installed on teh machiens I am having issues with?
    I did install a differnet NIC (a DLINK) into the desktop machine - but had
    the exact same issue - so it's not network card related...The desktop
    machine
    is a DELL Dimension 8300 with a built-in Intel Pro 10/100 VE
    ethernet adapter and the Laptop is a Compaq 700 - wireless card is a
    Trendware PCMCIA wireless network adapter.

    fyi...

    Here is the ipcong/all for the Dell Dimension machine that DOES NOT WORK...

    I cannot ping the gateway (192.168.2.2) - which is located at the factory -
    behind a wireless AP.

    I don't see any differences between the two really....

  2. Can you ping loopback? - 127.0.0.1
    Ping can be disabled on some wireless routers check there....
    Hope this Helps

    Can ping loopback no probs and any other machine on the lan except for the
    ones behind the radio - can also ping the first radio no prob (it's
    connected to the LAN via ethernet though) - it's having difficulties with
    the radio connected to that one via wireless... All other machines can ping
    all radios and the machines behind them no probs...
