NXC2500 Access Points randomly reboot

PatrickS

Hello,

all APs managed by our NXC2500 randomly reboot throughout the day.

I think it might be related to the following issue:

[SPR: 1806281062]
[eITS: 180500539]
[Symptom] The managed AP reboot, the alert log shows CAPWAP
AP Disconnect and alert CAPWAP AP SSID stop, it’s related with
smart antenna.

We installed version 5.40 in hope of fixing the behaviour, but sadly the reboots keep happening after the upgrade to the new version.

Here are the logs for such an event:

     AP SSID Stop. MAC:04:BF:6D:11:00:20,Radio:1,SSID:xxxxxx

As far as I can tell there are no logs written on the AP before the reboot. First log entry is "NTP update has succeeded." I assume this is from the normal boot process.

Please help!

Hi @PatrickS

When you see the log display again, could you collect the NXC and AP diagnostic info for us?
You can read this FAQ:
How to collect the controller/ AP diagnostic info by GUI?

Hi @Zyxel_Kathy

I sent you the diagnostics for the controller and one Access-Point via direct message.

Hi @PatrickS

Thanks for the diagnostics of the controller and AP.

Hi @Zyxel_Kathy
can you check the ticket for me? Sadly I was not allowed to answer the mail from Zyxel Communications <eitssupport@zyxel.com.tw>.

@PatrickS

I received your mail and answer your question that set the data mode to local bridge will mitigate the symptoms.
