Public bug reported:

eth0 - wired
eth1 - wireless

Wireless card: 2200BG on an Asus Laptop
All cases: internet works fine, pinging www.google.com always works.

Case 1: eth0 has static IP address configured (and gw) and doesn't have cable
plugged in

1) Choosing a wireless network will cause wireless not to ping LAN ip's.

'ip route' will show:

192.168.1.0/24 dev eth0  proto kernel  scope link  src 192.168.1.106 
169.254.0.0/16 dev eth0  scope link  metric 1000 
default via 192.168.1.1 dev eth0  metric 100

2) If one runs /etc/init.d/networking restart (ubuntu hardy's network init
script), it will start pinging LAN without a problem, and 'ip route' will show:

192.168.1.0/24 dev eth1  proto kernel  scope link  src 192.168.1.111 
192.168.1.0/24 dev eth0  proto kernel  scope link  src 192.168.1.106 
169.254.0.0/16 dev eth0  scope link  metric 1000 
default via 192.168.1.1 dev eth1 
default via 192.168.1.1 dev eth0  metric 100

3) If once again I choose the same wireless network from the applet's dropdown
list, I go back to 1)


Case 2: eth0 configured with DHCP instead of static IP

1) Pinging/accessing LAN ip's works like a charm all the time in wireless, and
'ip route' shows:

192.168.1.0/24 dev eth1  proto kernel  scope link  src 192.168.1.111 
169.254.0.0/16 dev eth0  proto kernel  scope link  src 169.254.7.11 
default via 192.168.1.1 dev eth1 
default dev eth0  scope link  metric 1000
