Comment 65 for bug 82927

Hardy Alpha 2 updated as of 1/24/2008 still has same bug. Network Manager disables eth0 and reports no network connection.

Activate connection as in "The Ubuntu Book" namely:

sudo dhclient

Network comes up just fine and logged onto BBC. Network Manager still reports "no network connection" even though there obviously is one, and for that matter there was no reason for Network Manager to disable eth0 in the first place since it works fine. lspci -vvnn reports "Realtek RTL-8029 ethernet controller. For some reason obscure to me during boot Network manager decides the Realtek ethernet card (which is already running at that point in boot), "does not support carrier detect" and disables eth0. Whatever that complaint is has nothing to do with the adapter working fine.
