When I power on my Pi 2, without a network cable attached, the green and yellow lights are illuminated permanently.
If I connect a network cable, no connection is made to my local network. ifconfig shows an IP address of 169.254.38.41.
I have many Pis embedded in various projects since the first Pi came out, so I'm fairly experienced with these devices, but I've never had a problem like this.
Any ideas? I think somehow the ethernet chip has got damaged.
