TL-WA860RE, Frequently Network device 'wlan0' link is down

Hello,

I have my first OpenWrt from few days installed on TL-WA860RE and it has dropped the internet in some intervals.

The TP-link is a client of the another wifi network, and it connects to it by wifi.
From TP-link there is a lan cable to another router, but I tried it with my PC, and the same thing is happening.

Maybe someone could help me resolve the problem.

|Model| TP-Link TL-WA860RE v1|
|Architecture| Atheros AR9341 rev 3
|Firmware Version| OpenWrt 18.06.8 r7989-82fbd85747 / LuCI openwrt-18.06 branch (git-20.029.49294-41e2258)|

It repeats again and again in different interwals. Sometimes it is 15minutes, sometime 10minutes.
I tried static IP adress for WWAN but it doesn/t do anything. I tryied different locations, even connected it to another router which is in the same network that TP-Link is connected. Deleted any ipv6 settings. Nothing works.

I have reset to defaults and only connect it to wifi.
the same thing occurs.

Does anyone has any idea what is going on?
I'm stuck with this problem, and have frequent internet connection loss for few minutes.

I am experiencing exactly the same thing on TL-WA860RE v1, so you're definitely not hallucinating.

OTOH, I have the same device at another location and it does not drop connection like this at all.

I've tested variety of different WLAN configuration settings, but random disconnects persist.

Hi, glad that I'm not alone.
Can you write what is your environment?

I have in my place network with multiple access points, with the same SSID on every device. But every device has different MAC and are on different channel of 2,4GHz.
Many flats are connected to this big network. I wanted the TL-WA860RE to make another private, small network, to isolate my devices (smart TV, smartphones, tablets) from the whole network. Because I don't want someone else to stream videos on my TV. The original TP link software doesn't have that option. Only working like a bridge, with full transparency.

When I set my device I have choosen the most strong signal and I entered its MAC adress. I wonder if it has a problem with that, because the signal strength is changing. Sometimes different device has better signal. But I have tried few and always is the same problem. I have read that some erlier version of open-wrt has a problem with a MAC filtering when the same SSID is used with multiple points.

Do you connect to the network that has only one SSID in your neighbor?
