[Bug 1241897] Re: Regression: Losing wired connection after upgrading to 13.10
** Description changed:
After upgrading from 13.04, Kubuntu holds a wired connection for a few
seconds and then drops it. I can untick "Enable networking" on the
Network Management tray icon and then tick it again to have the
connection back for a few seconds. That's what I'm doing right now to
submit this bug.
A workaround I've been using since upgrading is to boot latest raring
kernel from 3.8 branch.
- I also tested 3.11-rc6 and it seems to be already fixed in upstream.

Title:
Regression: Losing wired connection after upgrading to 13.10
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
After upgrading from 13.04, Kubuntu holds a wired connection for a few
seconds and then drops it. I can untick "Enable networking" on the
Network Management tray icon and then tick it again to have the
connection back for a few seconds. That's what I'm doing right now to
submit this bug.
A workaround I've been using since upgrading is to boot latest raring
kernel from 3.8 branch.
I also tested 3.12-rc6 and it seems to be already fixed in upstream.
