suggested getting a .tgz file and putting the .ucode in /lib/firmware so I guzipped it and copied that file to the directory (replacing a file there that was almost the same size). Was that right? In any event, it didn't make any difference that I can see.
Here are some diagnostics, in case they mean more to someone else than they do to me (which is a sure thing).
ifconfig shows eth0 and lo but no wlan0.
dmesg | grep iwl
