Problem between Zigbee2MQTT and WIFI EERO PRO 6

Has anyone encountered problems between Zigbee2MQTT v2.2.1-1 and AP WIFI EERO PRO 6 v7.8.0-5242? At night my AP WIFI goes down (WIFI client disconnect and they stay disconnected until next soft reset of AP WIFI)! Do you know if Zigbee2MQTT launches some routine every night between 3 and 4? Like 2.4GHz network scan?

Do you connect your Zigbee2Mqtt over WiFi ?

no, zigbee2MQTT use a Sonoff dongle connected to USB port of my Home Assistant…
