One additional point of interest. When the wireless crashes, running
`ifconfig` produces this:
eth0 Link encap:Ethernet HWaddr 00:26:9e:9d:f8:d7

Note the bizarrely high number of packets showing on the eth0 interface, which
has never been used on this laptop with Ubuntu 12.04. When wireless is working,
`ifconfig` shows:

Why is that?
