Hi im building a mesh network and i notice that there are some periods of instability when sometimes clients connect or the banana pi rp4 i have also joins the mesh (or wifi clients join them)
Dmesg pumps this out consistently: Im not sure how to read this can anyone help?
Overall symptoms show instability, the mesh nodes either crash from the network temporarily, but its pretty poor performance and sometimes comes to a hault until a reboot, but eventually ill have this issue later.
Removing the banana PIs from this network that using (Be14 MT7996) and dont see this errors anymore
Im using MT7915E/MT7975 in this edge node experiencing the issue on a QEMU/Docker container running openwrt -- not sure if this is related..
