Some more interesting data.

Open authentication at home works out of the box via wpa_supplicant
with ifconfig_wlan0="WPA DHCP" whereas it flaked out and died at work.

There are two instances of wpa_supplicant started up on the laptop.
Here's a snippet from pstree that shows that both processes are
standalone:
