WiFi stop to work

[Ratataplam]

Hello, I'm using i.MX8 and yocto.

I found this behavior during WiFi test with Laird Connectivity Sterling LWB device.

The test is a simple "ping" from embedded device to our server.

After some hours the host become unreachable because the WiFi interfcace stop to work.

ifconfig 

shows a wlan0 with right ip address and in up/running state.

If I switch to ethenet cable the host is reachable. 

None wlan0 down->up recovery the interface and  the unique way is a board reboot.

In dmesg I didn't found relevant message

Someone has found a similar problem ?

Thanks
