Plasma nm-applet won't show wireless connections

[Ksiencha]

Hello! I can't figure out where the list of wireless connections have gone, I only use wired connection currently and it is displayed as the only connection.

I work on Aspire V3-571G laptop, my wifi uses ath9k module.
I tried to search some info in terminal:

$ ip link

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
    link/ether 00:16:d3:e7:3f:9c brd ff:ff:ff:ff:ff:ff
3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DORMANT group default qlen 1000
    link/ether 68:94:23:1e:e2:51 brd ff:ff:ff:ff:ff:ff
4: mon.wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UNKNOWN mode DEFAULT group default qlen 1000
    link/ieee802.11/radiotap 68:94:23:1e:e2:51 brd ff:ff:ff:ff:ff:ff

Seems like wifi is UP and should be working, so I tried to scan connections:

$ iw dev wlan0 scan | grep SSID
command failed: Operation not permitted (-1)

$ sudo iw dev wlan0 scan | grep SSID
command failed: Operation not supported (-95)

I really don't know what it means. Please, help me solve this issue.
I appreciate everyone's time and commitment. ))

That's the thing - my wifi is not disabled, my laptop has an indicator and it's on, so wifi is working. For the sake of experiment I tried Fn+F3 (it has wifi icon on it) but it really didn't do anything.

I also have an ap-hotspot installed so that my laptop could share my internet with my other laptop, and it works. But somehow my laptop won't see available wifi connections.

Checkmark both the wired and wireless boxes.

It's funny thing but after I restarted my laptop it suddenly all worked:



But then after a few minutes the list disappeared again.
I literally don't understand what is wrong.

I think I know what the problem is. I checked a few times, only after I launch ap-hotspot app, the list disappears, seems like it blocks wifi somehow.
Oh, well, but thanks everyone who tried to help me
