Both HPC networks are showing up as ad-hoc (the "Mode:Ad-Hoc" line in
the output) and are not using encryption ("Encryption key:off"). The
signal quality is also low, which is may be why you are unable to
connect to them.

I've seen XP remember networks and subsequently rebroadcast them as
ad-hoc when I worked at a help desk. Here's a page from OSU about it:
<http://8help.osu.edu/3655.html>.

I'd second the suggestion to try walking around and pinpointing the
location of the devices. Not knowing what kind of building you're in,
they might be in another area / floor / room, or even a different
building next door.
