Hallo zusammen,
wollte euch nur informieren, dass mein Netzwerk nun wieder normal läuft. Es war wohl tatsächlich der AP. Keine Ahnung warum er auf einmal dieses Verhalten zeigte. Nur noch die Fritte stört aktuell.
Für alle die es interessiert, anbei die Antwort vom Unifi Support:
After reviewing your support file, I’ve identified a few specific configurations in your environment that are currently driving high CPU and memory load.
The most likely cause of the reported full-network outages is the gateway’s DPI process becoming unresponsive.
The gateway’s management daemon repeatedly force-restarted the DPI process during the reported outage window. Since DPI runs inline in the forwarding path, a hang in this process can disrupt all client traffic, which matches the reported behavior: complete network loss affecting both wired and wireless clients, while the ISP modem’s DSL connection remains stable.
To address this, please temporarily disable Traffic Identification, then monitor whether the outages stop. After that, please update the console to UniFi OS 5.1.15, as this version includes various stability improvements.
