Bug Description

If I have both Wifi and wired ethernet connected at the same time, I get no access to the internet. Internal virtual networks (Virtualbox) continue working and I can operate on any virtualised instances via ssh though.

Doesn't seem to be a DNS issue as pinging IP addresses directly time out.

As soon as I manually disconnect (not disable) the wifi connetion, internet starts working the instant after.

Maybe some sort of routing confusion?

The IProute info on the previous post does not reflect the network config at the time of the issue being reported - ubuntu-bug just won't work without access to the internet. I'd re-generate that info manually then copy&paste it here if I knew how to wrestle Ubuntu into giving it to me.
