R600 Ap high CPU Utilization

ajay — Tue, 09 Sep 2025 05:32:52 GMT

I have multiple R600 APs connected to an SZ104 controller. On several R600 APs, I am seeing high CPU utilization alerts in LibreNMS. However, no alerts are showing on the controller, and when I checked the AP logs and CLI, I did not find any indication of high CPU usage. Could someone provide a solution to this issue?

Hi Ajay,

The Controller and AP both are EOL products hence we would need to find any workaround related to specific feature enabled that might be causing high CPU on the APs. Is there any specific feature enabled or multiple WLANs in use with maybe high Multicast or broadcast traffic being hit on AP eth/Wlan port/interface ?

Best Regards
