[R2S Plus] FriendlyWrt WiFi spontaneously stops working

[Plaque-fcc]

FriendlyWrt version: OpenWrt 23.05.3 r23809-234f1a2efa / LuCI openwrt-23.05 branch git-24.264.56413-c7a3562
Symptoms: WiFi all of a sudden isn't visible unless you reboot the device. Alternatively, you can log in to LuCI web interface of FriendlyWrt and navigate to wireless section: this apparently restarts wireless interface (probably reloads hostapd, or something).

Months of usage don't let me tell which circumstance triggers this failure: it can occur within a few hours, or be separated by weeks.

The same situation, I couldn't solve this problem, I just noticed a pattern that in 2.4g mode it works more stable, but then the speed becomes so low that it is impossible to use. In general, a useless module for 10 dollars.

Moreover, this module doesn't work in both bands simultaneously, although it seems it should.

wifi now works stably on 5g if you select Country Code PA for example, but it does not start automatically when the device boots, the problem was solved by adding the line sleep 30 && wifi down && sleep 10 && wifi up to /etc/rc.local, now it works as it should, but unfortunately it does not work in two bands yet.
