Incidentally, does your e-mail use http or https?
    I've left this for the last few days since the IP address settled and I was able to get on with things as normal, but since doing a reinstall on another machine behind the router everything's now been shuffled about again. I notice that when I go into KNetworkManager the connection often shows as having been established for two or three minutes, even when I've been on it all afternoon with the same IP address. And there's no activity in the status bar icon to indicate that it is reconnecting at any time.

    My email is primarily POP-based from Thunderbird and hence I assume your question about http or https would only apply if I was using web-based mail?

    I tried doing this but am not sure about some of the other fields I need to complete. If I enter an IP address 192.168.1.66 for example, the Subnet Mask automatically fills out as 255.255.255.0. For the gateway I tried 192.168.1.1, left it blank or entered 0.0.0.0, and for DNS Servers and Search Domains I left them blank. Regardless, whatever I try results in the connection establishing itself but then I have no actual connectivity, not even to the router admin.

    It occurred to me, could it be that this powerline device is effectively 'stealing' the 192.168.1.1 gateway access and somehow hogging it all to itself?

    Correct.

    Typically it would be 192.168.1.1, but you can find for sure if when you
    have an automatic connection you run "ifconfig".

    That will not work. You can find them from "/etc/resolv.conf" with a
    working connection, or use google's (8.8.8.8)

    Might be... :-?

    This is not going to go anywhere unless you run some proper diagnostics such as wireshark + inssider. The DNS for a livebox could well be itself but there are various versions of livebox. CPL are widely used and normally cause no problems. Have you looked at what is attached to the other CPL, how it is configured and what it is doing?

    Which bit of info should I be looking at there? I'm not sure I'm seeing anything that would indicate the gateway.

    I think ifconfig is spelled "route -n" in this case

    Oops, right :-)


    That's the typical thing you do, look, and correct instantly if you are
    there, because you know.
