WiFi problems on Archer C50 v3

Installing and Using OpenWrt
1

Hello!
I have recently installed OpenWRT on my router and it is working great(well except the problem I have). I want to state that I am new to OpenWRT and a beginner in this field. I downloaded the image and installed as stated here.
The problem is that everything is fine until the WiFi drops. It is like one of the interfaces - wlan0 or wlan1 - is disabled, it is happening independently for each WiFi network. It takes some time and then both networks are up again. I have noticed that when this is happening the following is printed to the log:

Tue Mar  3 13:06:23 2020 kern.info kernel: [ 5135.833061] rt3050-esw 10110000.esw: link changed 0x05
Tue Mar  3 13:06:32 2020 kern.info kernel: [ 5144.907011] rt3050-esw 10110000.esw: link changed 0x07

There is my config file: link
I would like to know whether there is a fix or I should be looking for a new device.

Those messages are not wifi related-- it is one of the Ethernet port links going down and then back up as if the cable was unplugged and plugged back in.

Thank you for replying!
Then I really don't know what the problem is. All the LAN connections are excellent, my only problem is the wireless.

Those numbers are bit maps of which ports in the Ethernet switch have a link. 0x05 means ports 2 and 0 are up. 0x07 means ports 2, 1, and 0 are up. So for 9 seconds port 1 was down.

I have just found out that every time one of the the wifi networks is not working, in luci its status is stated as disabled but in fact it is enabled and just not working.

Hello, I have more info about my problem. These lines are from the log too and I don't know if there's a connection:

Tue Mar 10 20:49:05 2020 daemon.notice hostapd: nl80211: wpa_driver_nl80211_event_receive->nl_recvmsgs failed: -5
Tue Mar 10 20:49:05 2020 daemon.notice hostapd: nl80211: wpa_driver_nl80211_event_receive->nl_recvmsgs failed: -5
Tue Mar 10 20:49:05 2020 daemon.notice hostapd: nl80211: wpa_driver_nl80211_event_receive->nl_recvmsgs failed: -5

Nobody have any solution to this problem?

Hi everyone! I has similar problem with OpenWrt 19.07.8 r11364-ef56c85848 TP-Link TL-WR842N v5. Wifi is down sometimes in logs has no warnings or errors.
