Install the guessnet package. This will install the guessnet-ifupdown helper tool.
Now edit your /etc/network/interfaces file and add the following lines:
auto wlan0
iface wlan0 inet dhcp
wpa-ssid CompanyWLAN
wpa-proto WPA
wpa-key-mgmt WPA-PSK
wpa-psk S3Cr3tKe4
mapping wlan0
script guessnet-ifupdown
map default: wlan0-open
map autofilter: true # look for wlan0- interfaces
map timeout: 9
map init-time: 9 # for slow drivers
map verbose: true
map debug: false
iface wlan0-home inet dhcp
test wireless essid WLANatHOME closed
wpa-psk S3cr3tH0meKe4
wpa-key-mgmt WPA-PSK
wpa-proto WPA
wpa-ssid WLANatHOME
# if all else fails: pick an open network
iface wlan0-open inet dhcp
test wireless open
wireless-essid any
wireless-mode auto
This will first try to connect to the CompanyWLAN network and if this is not found, try the WLANatHOME. If everything fails, it will connect to any open Access Point.
