Duplicate IP address on Windows XP

Discussion in 'Home Networking' started by Peter Smithson, Sep 21, 2008.

  1. Hi,

    I've just got this Sitecom WP 130 wireless range extender working but
    there's a strange problem.

    If I use the old wireless PCMCIA card that I have, everything is
    fine. If I use the fancy 54mbps MIMO one, I get a message about
    "duplicate ip address". I've tried re-starting the hardware to see if
    there's some table that needs clearing out but that didn't help.

    I've tried setting the IP address manually but then it doesn't work at
    all.

    Any suggestions?

    Cheers.

    Peter.

    The PC is smart enough to notice that two adapters have the same
    address, and not smart enough to realise that you won't be using them
    both at the same time. Uninstall the old one and the message should go
    away.

  3. Hi,

    I don't think that can be it. If that was the case, then un-plugging
    the MIMO card and plugging in the old one would not fix the problem.

    Also, they shouldn't be assigned an IP address when the PCMCIA card is
    removed. If I type "ipconfig" with nothing connected, there is no IP
    address.

  4. I did cold boot the router too but I'm not sure what order I did it
    all in now so I'll try that all again when I get home. It might have
    forgotten by now anyway - I believe these things expire.
    I think I'm OK on that one for a while. The RE's IP ends with .254.
    The allocated IP's start at .2. I've not explicitly excluded it but I
    don't have that many devices. Good point though.

    Peter.
