    Just had a mate on the phone and has the following problem.

    His partneer has a nice new HP NC4000 and they have put a W400 Mini PCI WiFi
    card into it.

    He is using a BT Voyager 2000 modem router on TalTalk

    He also has an old Tosh laptop with a 54g PCMCIA card in it and that works
    fine in WiFi with the router so all appears well there.

    The NC4000 can connect to the internet via the thernet port hard wired to
    the router, but in WiFi mode it finds the SSID of the router and reports a
    connection, but when connecting to the internet via IE it reports a DNS
    error. It also cannot ping the router via WiFi.

    At first we thought this was a problem with the W400 card as it was bought
    used from eBay, but have also tried a USB WiFi stick and the 54g PCMCIA card
    from his Tosh laptop, and all give the same symptoms.

    So last night I talked him through fixing the DHCP range in the router to - 255, router has IP

    Then fix the IP address of the WiFI connection inthe NC4000 to IP addy, subnet gateway
    Prefered DNS Sec. DNS as

    He has now done a clean install of XP Pro with SP2 and all of HPs updates,
    and still has no WiFi access to the internet. Wired is still working. Wired
    connection works with both fixed IP address of say or obtain

    We also tried this yesterday on my home LAN with WiFi using his Tosh, my
    N410C and the above NC4000, the other two laptops were OK but the NC4000
    still refused to connect in IE. Thats is when the XP istalation seemed
    flakey, and I suggested a reinstall, but still the problem remains

    Any idea gfolks, this one has me baffled.

    Without wanting to sound flippant, because I am not a networking expert - I
    don't think so - because he can get a connection on his Tosh Win98 laptop
    using an Edimax 54g PCMCIA card and the Edimax client app. Using exactly the
    same card and client app on the HP NC4000, no connection in IE.

    Thanks for the first response anyway

    Why are you using router IP's as DNS addresses?
    Why have you the same IP address for your wireless card as your stated
    sec DNS address?

    mmmm, strange one

    Here's a couple of things to check

    Is XP's firewall turned on? is there a third party firewall, have yo
    checked the rule set.Ie, nobody's accidently told the firewall software not to allo
    connections through the wifi adapter
    Also, more likely, Has the router got MAC filtering enabled? If it a
    then either disable or, preferably, add the wifi adapters MAC address t
    the routers filter list
    Finally, can the laptop see other machines on the network or is it al
    dark via the wifi
    If I think of anything else I'll report back

    Cheers Terry

    I'll get him to check WinXP firewall is turned off.

    Also running Sygate Personal Firewall, but he gets the same result with that
    turned off. Also does not get the usual pop up when going into IE for the
    first time via a particular connection.

    MAC filtering is turned off at the moment.

    Basically with SPF turned off the onboard wired NIC works and the WiFi does
    not, even using three different adapters.

    Tried both manually configured IP / gateway / DNS as above and also in full
    auti on both wired and WiFi - same scenario, the onboard wired NIC works and
    the WiFi does not

    Thanks again

    Another thought ;

    What software is controlling the wifi card? For simplist/best setu
    make sure you have SP2 and allow XP's built in wifi software to control th
    card instead of the manufacturer's software. I found this to b
    especially important for belkin wigi products

    Hi Conor

    Drivers ....????

    The HP W400 card...used both the driver that was on the HP NC4000 driver
    disk and the latest one from HP's web site

    The Edimax 54g PCMCIA card again using the latest driver and Client app from
    Edimax. The exact same Edimax card works fine in my Compaq N410C and in my
    mate old Tosh Tecra so not sure why you say drivers...unless you can
    enlighten me further....
