MACs & cable modems...

[linuxguy at ici.net (linuxguy at ici.net)]

I got it all working today.  I purchased my in-law a  LinkSys Cable router,
and went to work trouble shooting his cable modem connection.  I dropped my
Linux laptop into the mix and readily determined that it had to do with
the Macintosh's TCPIP settings.  Cable connection was fine.

  + I configured the Linksys cable router with the proper 
    MAC (hardware) address & new admin password.  Rebooted and 
    it came right up.

  + I then attached my linux laptop which got a DHCP address from the
    router, and away went my laptop.  DNS, default route... everything
    was great.

  + Turns out, on his macintosh....
    in the Chooser->TCPIP settings, in order for DHCP to work,
    one must select DHCP & blank out all IPs and DNS entries in the dialog.
    I couldn't tell if the DNS entries were manually inserted or DHCP'd, 
    but after comparing what the Macintosh had for DNS, and what my laptop
    had, it was obviously wrong.

So that was it... Now everything is fine....  His Macintosh is still slower
than a ...<insert you favorite southern expression here>... but it's working
as should be expected for a MAC I guess :-?
