Great suggestions. I think I've benefitted from your advice
several times of the years, directly and from reading your posts.

I booted from a different kernel, same result from ip addr
show eth1.

2: eth1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
    link/ether 28:d2:44:1a:e0:ca brd ff:ff:ff:ff:ff:ff

I'll try with a live CD, or USB drive. I've got a hard
drive in the CD bay at the moment. The notebook is new used, but
the system has been the same (with upgrades) for
probably 15 years. I haven't done a fresh installation
for a long time (except as a VM).

What a great resource you are, oh bearded ones!
