Client disconect on OpenWrt 18.06.1/18.06.2 with TPLink WR841n(d) V13.0 and V13.1

Hi there

Is the wifi not stable which was in LEDE, still not solved for TPLink WR841n(d) V13.0/V13.1?

I ve problems with OpenWrt 18.06.1 as 18.06.2 and TPLink WR841n(d) V13.0 and V13.1.
Clients disconnects from Ap and there is not anymore working until restart of device.

wifi restart does not work it hangs...
I have also dmesg and logread output.
Output of ps after entering in badstate...
showHosts, getConnectedHosts are scripts which shows connected clients (loop over "iw dev wlan0 station dump" and awk stuff) ...

I have my own compliation, but I guess this has nothing todo...
Nobody else having problems with this?

Clients are not more reachable after some time, they disonects and connects not anymore.
wifi restart does not work, you must do a poweroff/poweron cycle.

I can debug the stuff with information how to insert debug statmente.
I compile the whole stuff! Or someone can send me a modifed file which will log information of wifi connections...

Should I open a ticket?
