[WORKAROUND] Cannot connect to any WiFi network after resume

Question

Hi, I'm having one weird problem that makes my laptop not as mobile as I'd like it to be..
Literally, I have to boot it up again after each move.
Here's the issue: if I suspend to ram, and then resume in a place with different WiFi network, it can't connect to Internet again.
I'm using NetworkManager via corresponding plasmoid in KDE (although, nmcli does not work either).
When I click a network name, I get the following:
"Configuring interface" .... -> Cannot connect to {NetworkName}
(the labels might be a bit different, as I get all notifications in my local language)
Have anyone experienced this before?
Or, AT LEAST, how can I get a bit more verbose output from NetworkManager? Is there a log file?
Here's the hardware:
05:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)
Here's what I've tried already (and it didn't help):
# systemctl restart NetworkManager
# modprobe -r ath9k
# ncmcli nm sleep false
WORKAROUND FOUND: When I get "Configuring interface" .... -> Cannot connect to {NetworkName} (it happens not only after resumes, btw), I type the following in the console:
sudo dhcpcd -k
So much time passed, so many updates -- still have to do this manually... %)

Here's what I've tried:
# stop NetworkManager first, just in case if it would not start anything before time
sudo systemctl stop NetworkManager
# kill wpa_supplicant (one of suggestions in the topic)
sudo killall wpa_supplicant
# re-load kernel module with nohwcrypt=1 (another suggestion in the topic):
sudo modprobe -r ath9k
sudo modprobe ath9k nohwcrypt=1
# start NetworkManager again
sudo systemctl start NetworkManager
Then tried to connect the network again: the issue is till the same. Here's the latest dmesg:
