here's what i put into my conkyrc to detect whether i'm using wired or wireless internet (or vpn). i imagine this could be cleaned up a bit, but it works quite well.

${if_empty ${exec cat /proc/net/arp | grep eth1}}${if_empty ${exec ps -e | grep pppd}}${alignc}${color white}wlan0: ${addr wlan0}$color
