One further detail which may or may not be related. When I login from gdm screen to gnome desktop (wireless setup with Roaming disabled & static ip -- so wireless not working as described above -- & wired eth0 physically disconnected -- so no outside data communication at all), desktop loading is very slow (maybe 10 times slower than when some network connection is present). Also, desktop operation is slow ie. takes 10-20 seconds for a terminal window to open, takes 10-20 seconds for System>Administration>Network to open network manager.
The bug I describe above may be connected with other reported 'slow desktop' bugs such as Bug #94048.

Perhaps avahi is to blame here as well???
