Package: network-manager
Version: 0.6.6-2
Severity: important
When the Ethernet plug is not connected, network-manager is not
connected, despite the availabity of a broadcasted unencrypted 802.11g
network. This happens on 2 machines on 2 tested. Both machines are
laptops with one Ethernet card for eth0 and one 802.11g card for wlan0.
This happens with the default /etc/network/interfaces, but to eliminate
problems that could be caused by a conflict between eth0 and wlan0, I
set eth0 so that it's not managed by n-m. The problem persists.

As you can see, this network is an easy target, and I can connect to it
trivially with iwconfig and dhclient, on both machines. This machine
uses an IPW3945, with the firmware of course installed. The other
machine uses a Ralink RT2500. Both machines run a standard
freshly installed lenny, with a stock Linux, 2.6.26-1-686. Both use the
mainline Linux driver. I shall remember to attach the interfaces file.
nm-applet shows no clue. When Ethernet is unplugged, I see a X on red
and no activity. The tooltip reads "No network connection". This
happens without touching to n-m. "Enable Networking" and "Enable
Wireless" are checked. This happens despite multiple reboots.
