OK it looks like eth0 (your wired connection?) is trying to get an IP 
address but nothing is giving it one. Are you sure that there is a DHCP 
server running that will give your machine an IP address? Is an network 
cable plugged into it?

What happens if you just comment out the 'iface eth0 inet dhcp' line? I 
think that this will start up your wired networking so that if you were 
to plug something in than everything would work. If you don't plug 
anything in, it should sit idle.

The wireless isn't looking to the /etc/networking/interfaces file to 
determine its behavior. It is determining its behavior from the network 
manager (I think).

I am not sure what makes the WiFi run.

If I am really lucky then commenting out the line above should let the 
network manager handle the wired connection and it should start working 

Good luck let me know if it works.


To be or not to be, that is the question
                2b || !2b
(0b10)*(0b1100010) || !(0b10)*(0b1100010)
        0b11000100 || !0b11000100
        0b11000100 || 0b00111011
        255, that is the answer.
