Bug Description
I have set-up a bridge (br0) on eth0 of my laptop, as I'm using KVM from time to time.
This is the content of /etc/network/
aaa@xxx:~$ cat /etc/network/
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
#
auto eth0
iface eth0 inet manual
auto br0
iface br0 inet dhcp
bridge_ports eth0
bridge_stp off
bridge_fd 0
bridge_maxwait 0
My problem is, if I boot WITHOUT a live connection plugged into the ethernet port of my laptop, NetworkManager sees my WiFi as "disabled by a hardware switch". As such, I can't use WiFi when there's no LAN. I can use WiFi when there's a LAN connection present, but it defeats the purpose of having a WiFi connection.
