The important issue here is what does the routing table look like. With 
both connected, run the route(8) command with the -n parameter. Take a 
look at your route while on wireless only
Kernel IP routing table with Wireless only
Destination     Gateway     Genmask    Flags Metric Ref    Use Iface
192.168.0.0     0.0.0.0       255.255.255.0U  2         0        0 eth1
169.254.0.0     0.0.0.0       255.255.0.0    U  1000   0        0 eth1
0.0.0.0         192.168.0.1   0.0.0.0            UG 0       0        0 eth1
Kernel IP routing table with both wireless and wired note default route.
Destination     Gateway     Genmask    Flags Metric Ref    Use Iface
192.168.0.0     0.0.0.0       255.255.255.0  U     1      0        0 eth0
192.168.0.0     0.0.0.0       255.255.255.0  U     2      0        0 eth1
169.254.0.0     0.0.0.0       255.255.0.0     U   1000   0        0 eth1
0.0.0.0         192.168.0.1   0.0.0.0         UG       0      0        0 
eth0

I've seen cases where NM fails to set up the default route.
