    I ought to know the answer to this but....

    My domestic network runs in the 192.168 etc etc band of IP addresses.

    My wife has just acquired a laptop from her work, (Centrino with a
    built in wireless adapter) which has an IP address in the 169.254 etc
    etc range.

    Its been setup so that she doesn't have administrator access to change
    the IP address

    Will it connect to my network as it is? (ie, is the difference in the
    IP addresses a terminal problem?) The reason I ask is that it doesn't,
    but I don't know if this is the problem, or whether there's something
    else to look for. It seems to give every indication of *finding* the
    network, (showing good signal strength etc etc), but it won't ping and
    it won't file share

    You need to add the SSID and WEP encryption key settings of your
    wireless network to those of the laptop as an acceptable
    alternative network. That should enable pinging to work. However,
    as you can't change TCP/IP settings, I'd hazard a guess that the
    wireless network settings are also locked down.

    The 169.254 range is one used by recent Microsoft products. It was
    originally intended for use on networks with no DHCP servers. Machines
    with dynamic addresses will adopt an address in that range if they can't
    find a DHCP server. If your wife's machine is configured for dynamic
    addressing then you can fix the problem by putting a DHCP server on your
    network. If the machine has been configured with a static address in the
    169.254 range then the solution is for you to change all of your
    machines to have static addresses in that range.
