Hi again Luke,
Had a little prob using the commands. Lost eth0 and connection for a bit and sudo ifconfig up and /etc/network/interfaces restart didn't work.  Slight bit of panic-:))
But sudo ifdown eth0 and ifup eth0 fixed it. You see, I'm using eth0 now and wired into the router, so lost my connection when I ran your commands.
Apparently both cards are auto configured, so I removed auto wlan0 from interfaces and reran your commands on wlan0 to see what it says. HTH.

When both card were down after I lost my connection no machine IPs were shown.
