    ping localhost is 100% guaranteed to work ... as long as 127.0.0.1 is in
    /etc/hosts and you do use /etc/hosts in your /etc/resolv.conf

            - ping of it's own ip# will always work evenwith the ethernet
            cable disconnected

    what is your contents of /etc/hosts and /etc/resolv.conf

    192.168.0.1 is presumably your router thru which you expect to get out
