it possible 10.04 still trying use old network interface. try delete file /etc/udev/rules.d/70-persistent-net.rules, , re-boot. file automatically re-created, whatever nics have now. (and "delete" mean save under different name, possibly restore later, in case not work expected.)

not know answer question asked (i use ubuntu server).
