Rob,

  Yes. And it was doing just fine until a couple of weeks ago.

  Nope.

  The 'ifconfig ...' works just fine. But, as soon as I press [Enter] for
the 'route add default gw ...' I see: SIOCADDRT: Network is unreachable.

  ifconfig shows both eth0 and lo up. But, eth0 has receive packet errors
and does not display an IP address. 'route' shows only localhost (lo).
'route -n', after running ifconfig with the explicit eth0 address, shows the
Destination of 192.168.55.0, but the gateway is 0.0.0.0.

  The WiFi card is not in. I want to get the wired connectivity working
again -- consistently and upon booting -- before more attempts at the WiFi
access are made. Wait a moment ...

  I just remembered that Kurt suggested that I turn off the WAP. When I do,
ifconfig shows the proper IP address. Still can't ping ... but I'm rebooting
the notebook. Rats! No difference. That is, the network still doesn't come
up on the notebook. But, I suspect now that this has something to do with
the switches. Perhaps I cannot daisy-chain two regular LinkSys 4-port
switches and a LinkSys WAP. Anyone have an 8-port switch I can borrow to
test this theory?

Thanks,

Rich
