Just a "me too" for this annoying bug! Sometimes disconnecting/reconnecting for 5-10seconds the cable works, sometimes running ethtool -r eth0 also helps (but again, just sometimes), and sometimes disabling/reenabling n-m in the KDE n-m applet helps. But restartin the n-m daemon immediately solves the problem.
Another n-m bug which stays unresolved for years... :-( -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
