Bug Description
The network connection doesn't reestablish on resume from suspend and the laptop has to be restarted.
Restarting networking or network-manager doesn't make it reconnect either.
However, unloading iwlwifi and reloading it, then restarting the network stack makes it work again.

the log has 'wlan0: authentication with ... timed out' warnings, looks like rather a kernel/ driver/ wpasupplicant issue
