Comment 19 for bug 121566

I can ping my router, but nothing else on my LAN, or on the external internet - there is a network unreachable error. Choosing connection information in the NM applet shows apparently normal IP and DNS information.

This all started to happen some time ago, but did not happen with my original clean Tribe 4 install.

Uncommenting the eth0 iface line in /etc/network/interfaces makes the problem go away.

Thanks for your help.
