TL-WPA4220 - WiFi functionality hangs after a day or so

Hi,
I have a problem with WiFi functionality. After a day (sometimes later, sometimes earlier) WiFi network disapears. eg. is no working and any device can see it anymore. The connection through ethernet cabel is still working. So it's something wrong with WiFi functionality I guess. If you plug-off and plug-it again, it strats working. Constantly reboot the device is not a solution in my case.
I see many users post the same issue here for weeks(!) with no helpful reaction :-(.
Have you got any solution?
Firmware version: 4.0.3 Build 20190326 Rel.43406
Hardware version: TL-WPA4220 v4.0
TP-LINK Team, could you be so kind and advise what should I do to use your product?

Hi, All.
Thank you very much for your continuous concern about this case.
Recently, we had several feedbacks that once TL-WPA4220 updated to the latest firmware, the internet connection would be very unstable such as not connecting to the Wi-Fi, and/or the Wi-Fi just disappearing.
If you had a similar issue, we suggested that you could roll back to the previous firmware: https://static.tp-link.com/2020/202010/20201030/TL-WPA4220_180308.zip to have a look.
And if it did not make any difference, please feel free to update here or send me a private message.
Thanks a lot.
