Comment 2 for bug 73381

I can confirm this.
Not using network-manager, I would expect acpi-support to reload my network cards configurations from /etc/network/interfaces.

But actually, it seems that avahi is taking over :s
This is the output of ifconfig after resume (eth1 being the wireless interface):
 ifconfig

In order to get my wireless I need to run
$sudo /etc/init.d/networking restart
