Would that be after a certain kernel? But I used 14.04 with kernel 3.17

See if it can help

Thanks by I don't find my case there.

Description=Reload Atheros 802.11n wireless LAN cards driver

ExecStart=/usr/sbin/modprobe -r ath9k
ExecStart=/usr/sbin/modprobe ath9k


# systemctl enable ath9k-reload.service

# systemctl suspend
          & RESUME

# systemctl hibernate
          & THAW

# systemctl hybrid-sleep
          & RESUME||THAW

Does it work?

Actually no, it doesn't. I already suspected that as I tried other similar 
(non-systemd) scripts that restart stuff on resume.

With this script, it doesn't even autoreconnect on boot (which did work 

I am starting to believe that after the drivers go up, an event scan is 
started, and the ath9k incorrectly reports that it is done (but might not 
be, as I have 2.4G and 5G and am trying to reconnect to the 5G).

Just restarting drivers won't fix this (if it is indeed so).

I need a delay after resume and scan, and before the autoconnect starts.

BTW when I do:
lsmod | grep ath
