[Pkg-utopia-maintainers] Bug#514943: network-manager: wired connection remains with wireless associated and no cable

[Drew Parsons]

Package: network-manager
Version: 0.7.0-1
Severity: normal

A change in network-manager behaviour appears to have been triggered
by the 2.6.28 linux kernel.

Up till now, I've had network-manager automatically connect to and
switch between wired and wireless networks.  At work I insert the
cable, and my wired connection is set up.  I take my laptop home, and
it finds my wireless network, the wired connection is switched off.

Now all of a sudden I've found that when I get home, the wired
connection is still on, even though no cable is inserted to the
ethernet jack.  At the same time the wireless network is still found
and set up.  But because nm has already set up the eth0 interface, the
gateway and dns (/etc/resolve.conf) is not rewritten. wlan0 is routed
to the local network only, the gateway is still set to the eth0
address.  So I can't connect properly to the external internet from
home.  

The only way I know to work around the problem is to switch off
"Connects automatically" in the nm configuration entry for the wired
network.  This makes it less convenient at work, where previously I
just had to plug in the cable for nm to set up the connection.

As far as I can tell the only change I've made to cause this new
behaviour is to install a 2.6.28 kernel (well, bind9-host also got
upgraded over the weekend along with associated libraries).

Thanks,
Drew
