Daniel,
Oh.

I su'd to root and added the eth0 interface to /etc/network/interfaces,
after lo. It still does not see the network after a reboot.

Yup. After 6 years with Red Hat I switched to Slackware 7 years ago and
I've become familiar and comfortable with its workings. When I assembled the
new system last Monday (with the old hard drives) there was no network
available. I read dmesg and saw that what had been eth0 on the old machine
was now eth1. I made those changes in /etc/rc.d/rc.inet.conf, restarted
inetd, and the network worked. I don't know Debian and its offspring, but
Xubuntu worked on her former laptop where Slackware had issues with the
wireless networking so I installed the same distribution on her new machine.
Since I'm not a professional SysAdmin I don't have the insights you pros do.

I'll look again tomorrow evening, or whenever I have access to her laptop.

No connection seen. I cannot ping the router ("Network not reachable") or
any other host.
Thanks,
