Hi, I have WL1837MOD WiFi module in AP mode. Our device use Linux OS, kernel 4.14.138. From kernel log:
wlcore: wl18xx HW: 183x or 180x, PG 2.2 (ROM 0x11)
wlcore: loaded
wlcore: PHY firmware version: Rev 8.2.0.0.242
wlcore: firmware booted (Rev 8.9.0.0.79)
It works fine in the most cases, but sometimes (seldom) it starts and doesn't work. In this case fwlog is full of "Tx Beacon: Beacon Expiry. Consecutive Beacon Miss" messages, see attached 45407450.csv log file. AP cannot be discovered by scan. Hostapd status looks fine:

Unload/reload of kernel module and restart of hostapd helps. AP is located in laboratory with many (more than about 30) other APs around.
My questions:
- What this message mean - exactly?
- Was beacon actually sent or not if this message occurs?
