[pkg-wpa-devel] Bug#525101: wpasupplicant: fails to run DHCP after resuming system in new network

[Marcus Better]

Package: wpasupplicant
Version: 0.6.9-2
Severity: normal

In roaming mode, when suspending the laptop while connected to one
network, moving to a different network and resuming after a while, the
system correctly associates with the new access point, but it does not
get a new DHCP lease. The network interface wlan0 is still configured
with the now invalid IP address from the old network. I have to run
ifdown and ifup manually to get a new address.

/var/log/daemon.log after resume:
