Hi there,

I'm seeing strange temperature spikes in some of the wAP AC devices, which are not corelated to high cpu or bandwidth usage.
Users are reporting poor performance while this spikes are happening.

Do you have any idea what this might mean or how to stop it?

Please see graphs from Observium for this problematic device:

Any toughts or advices will be higly appreciated.

I forgot to mention that temperature drops after restart.

Does wifi perform equally bad on both frequency bands during those periods? If 5GHz sucks much more, this could be sign that QCA9880 (5GHz WLAN chip) gets into some busy loop... And that 2.4GHz is only collateral damage.

Yes, I think both bands are affected.

Nobody else is experiencing this issue?
