    I've 3 PCs at home, a fon point and now a voip device (linksys 3012 if
    I ever figure out how it works, I could do with some advice on getting
    the syslog onto a pc), all wired. I've connected a spare netgear
    dg834pn wireless router to the origo router/adsl modem and disabled
    dhcp. It works fine but I'm a bit concerened the netgear doesn't
    appear on the network (though devices attached do) and I can no longer
    access the netgear web server pages from my PC, cause for worry or
    should I just accept it works?

    If you are going to have two routers on the same subnet then you have to
    deal with two issues. The first is that you can only have one DHCP
    server, so the server in one of the routers must be disabled. The other
    is that the routers themselves don't use DHCP so they have to be given
    compatible IP addresses. That is one of them needs to be given a static
    address that is on the same subnet as the other machines, but not in the
    range given out by the DHCP server.

    This should fix the problems you are having.

    You can use a machine to bridge two networks, that PC needs one NICs in it
    for each attached router. That way you can have multiple routers with DHCP.
    This function is built into Windows XP (I only happen to know this as I
    recently had to do it, haven't tried it with more than two routers or other
    OSs yet).

    Yes I have done this, the origo router is enabled and hands out
    addresses in the range 10.0.0.4-10.0.0.15, its address is 10.0.0.2.
    The netgear is dhcp disabled.
    Thanks, now I think the fon point is seen as a router and it's a bit
    flaky, I have assigned it 10.0.0.3 and I will give the netgear
    10.0.0.1.

    I don't understand subnet masks, are they ORed or ANDed before a
    request is sent out? As the windows box is set to automatic I assume
    it has the same network mask.

    Because the origo router seems a bit slow in handing out addresses I
    see the Kubuntu box seems to default to 169.254.97.2 and a subnet mask
    of 255.255.0.0 but the router sees it as 10.0.0.8 and it accesses the
    wan ok, I have no file sharing between boxes at present.

    Thanks
