If I understand your problem correctly, you need to stop eth0 becoming the 
default route. You can do this if you edit the eth0 connection settings, go 
to IPv4 tab, then the Routes button. Then click "use this connection only 
for resources on its network". Then wlan should remain the default route at 
all times.
