I've got F20 on an old laptop I'm using as a router. The external
interface uses the RJ45 port. The internal uses a USB ethernet adapter.
Every 2-3 weeks, the internal USB adapter fails. I can fix it by just
moving it to the other USB port. In another 2-3 weeks, it will fail
again, and I move it back to the original USB port, and so on.
No problems with the external RJ45 interface.
The logs aren't very helpful:

This looks like a USB problem. Is there a way to get usb (or
NetworkManager) to reinitialize the driver when this happens?
