Immediately after posting I noticed that both your wired (eth0) and 
wireless (wlan0) interfaces are using the 192.168.1.0 network. This 
strikes me as a likely source of problems.

Here is the equivalent output from my Ubtuntu laptop:

[markir at zul:~]$ netstat -Frn
Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt 
Iface
192.168.1.0     0.0.0.0         255.255.255.0   U         0 0          0 
wlan0
169.254.0.0     0.0.0.0         255.255.0.0     U         0 0          0 
wlan0
0.0.0.0         192.168.1.1     0.0.0.0         UG        0 0          0 
wlan0

i.e no eth0 - if I  specifically list  lwan0 and eth0 setup, I see that 
eth0 is unconfigured (as it should be...):

 [markir at zul:~]$ ifconfig eth0

It might be worthwhile to post the output of these commands from your 
'ubuntu' host.

Cheers
