Hello everybody.

My network still refuses to work after all.
Since I am not a network expert, I can't figure out
what is going wrong at all.
In short, everything looks all right with netstat and ifconfig,
but I can't get a byte going through the modem ! Ping says
"Network is down". (see in appended log)

If you understand this mess, please let me know.
