Just a follow up on this issue> spent all afternoon with ATTYahoo chat and tech support, trying to find out my router IP.  Oh, what a headache that was.  But did find out that my router IP is the same as the gateway IP.  Still cant ping.  Output is:
>From icmp_seq=1 Destination Host Unreachable
But, I still get online, can ping my maching and ping the static IP and nameservers used for the static IP's, all ok.  AttYahoo tell me I should be able to do so using the same nameserver/gateway used for DHCP,, but I can't in spite of everything else working.  Need some new idess, ATT tech support can't do it.
