Keith had suggested route -n earlier, so I tried it:
When network is broken or functioning it is the same:
parents at R2D4:~$ sudo route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.0.0     0.0.0.0         255.255.255.0   U     0      0        0 eth0
169.254.0.0     0.0.0.0         255.255.0.0     U     1000   0        0 eth0
0.0.0.0         192.168.0.1     0.0.0.0         UG    100    0        0 eth0

I will look into the man pages to see if another option would be better.
