Internal hardware watchdog time out??

AMcIntosh

This morning I had a complaint from a user saying that his WiFi dropped out whilst on a Teams call.

Checking the Nebula dashboard I could see that there was 1min where the connection dropped. On further investigation of the even log, I could see that at the very time of the drop, the AP (NWA50AX Pro) had reported "device is rebooted by internal hardware watchdog timeout"

Any idea what this is or what causes it??

I have sent the Diagnostic file via message (rather than post here)

Hi @AMcIntosh

After checking, we need your help to enable Zyxel support access for us to check if this issue happens before and monitor from event log.

Additionally, device is rebooted by internal hardware watchdog timeout is a protect feature that prevent the AP becomes unresponsive or encounters a deadlock.
