Rich,
   This is definitely a routing problem. Does it work with the wired
connection?
Also, in /etc/network/interfaces, get rid of these two lines

auto eth0
iface eth0 inet dhcp

This is very likely what is adding that extra 169.254.0.0 route and could be
the cause of confusion. At least we know they are unncessary because you
don't have an eth0 interface. More likely it is a routing problem in your
router, but delete those lines, restart your network and see if that helps.
