Hmm, maybe scratch at least some of that - it probably just means your
lan cable is plugged in. I walked my laptop over to the router and
plugged a lan cable in and now I get something more like what your
output was:
[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
eth0
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
eth0
0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0
eth0
However, I do notice that you have your gateway attached to *both* eth0
and wlan0 - i.e your last 2 lines:
0.0.0.0 192.168.1.254 0.0.0.0 UG 0 0 0
wlan0
0.0.0.0 192.168.1.254 0.0.0.0 UG 0 0 0
eth0
whereas my machine has only 1 entry - and it changes from being attached
to wlan0 when I'm using the wireless to eth0 when I plug in a lan cable
(this machine is running Intrepid). This could well be a source of trouble.
