There are many possible causes.

This evidence is not very useful; it only proves that NetworkManager was
running already, and therefore that a failure of NetworkManager was not
the cause of failure to detect wireless networks at school.

I suggest you do this test on each affected XO:

	sudo iwlist eth0 scan

... and see if the wireless networks at school are shown.  If they are
not, then either they are not present, the wireless card may be faulty,
or the antenna cable may be faulty.
