Additional info: I'm happy to do any experiments, network dumps, etc.
If you create a profile in /etc/sysconfig/network-scripts called ifcfg-wlan0, this will work correctly. This is what mine contains: DEVICE=wlan0 BOOTPROTO=dhcp ONBOOT=no
dhclient comes from the dhcp source package.
I am closing this bug since a it was a setup problem. Dan
