Wireless stop receiving packets with Openwrt and LEDE

Installing and Using OpenWrt
1

hardware ：QCA9531.
System ： LEDE or Openwrt（CC）

The wireless works normally for a long period of time, which may be a few days or weeks. At random times, the interface wlan0 stops receiving wifi packets.
RX bytes is No change ；station（Mobile phone or PC） wifi connection disconnected。

I got the same problem on different the company routers。

What should I do? thank you very much！！！

Well, you could start by using a supported version or (preferably to be able to track bugs) master.
