TL-WA1201 disconnects users

Hi
I have two TL-WA1201 APs. One is in an area where relatively few devices connect and is abolutely fine. The other is in an area where eaily 25 plus devices connect (laptops/ipads/Echos and Particle Photons). The device with higher usage will "lock up" serveral times a day, requiring a power cycle (off/on) to get it working again. By "lock up" I mean that all devices are disconnected and presented with an incorrect WiFi password error.
I tried a factory reset and only changing SSID and password, no joy the problem persists.
The system log shows the following errors:
Hardware Version: TL-WA1201 v2.0
Software Version: 1.0.0 Build 20191204 rel.41918

@boyek Hello,
The beta firmware in the thread helps with freeze or issue of AP from some customers' recent feedback, you could give it a try .
For the firmware regarding FragAttack, that will take longer time, and it is suggested keeping an eye on firmware update on official website.
Here is a statement and also some suggestions to avoid the attack as much as possible when using your network devices:

@Solla-topee Hi, working with beta software or keeping an eye if there will be update is not what anyone have time to do it (aware people just get rid of risky hardware from their network and go for safer options on the market). Regarding any statements or advices (instead of just releasing update for all affected hardware), your link is not working ("Oops! The page you're looking for can't be found.")...

Hello everyone,
Here is a new beta for TL-WA1201 for issues when working in multi SSID mode / different VLANs :
https://static.tp-link.com/beta/2021/202106/20210628/TL-WA1201v2_eu-up-ver1-0-1-P1[20210628-rel55053].zip
If your current firmware is not stable enough, please give it a try and feel free to let us know if works for you.

Hello,
I have the same issue with this ap, although only four devices are connected to it.
The devices lose the connection and can’t reconnect, I can’t even open the web UI via LAN to take a look at the logs.
The ap is inaccessible.
I have to hard reset the ap (off/on) to get it working again.
I already installed the latest beta from this thread and set a nightly reboot to circumvent this issue, without success.
What should I do?
Edit: it happened again after three days.
Wifi devices can't connect to the ap, can't connect to web UI via LAN either.
Your beta does not fix the issue, could you please take a look at this?
Sadly I am unable to return the device to Amazon.
