Mein UDR „friert“ immer wieder ein. So 1–2 Mal im Monat. Muss dann den UDR ausstecken und wieder einstecken. Hab unifi angeschrieben und um Hilfe gebeten. Hier kam raus, dass ich vermutlich einen Netzwerk loop habe.
Nun aber die Frage (Mail von Unfi dabei) wie kann ich den Loop finden? Ich kann ja die Geräte am Switch nicht abwechselnd 4 Wochen ausstecken, um auszuschließen, woran es liegt und dass jedes Gerät mal 1 Woche offline war... hiervon ist 1 Gerät 1 Access-Point? Gibt es hier Tipps? Gibt es eine Software, um das zu suchen?
Zu meiner Konfiguration:
Erdgeschoss UDR und 2 Geräte per LAN angeschlossen und 1 Netzwerkkabel in den 1. Stock
1.Stock. Hier das Netzwerkkabel in den Unifi USW Lite 8 POE. Hier sind 4 Geräte per LAN angeschlossen. Das ist alles. Rest alles per W-LAN verbunden.
Hier die Mail:

Network loops can lead to significant disruptions in network performance and intermittent outages. To address this issue, please follow these steps:
1. Begin by visually inspecting all network devices in your setup. Pay close attention to any potential misconfigurations or cable connections causing the loop. Ensure that there are no accidental loops or redundant connections in the network.
2. Temporarily disconnect devices from the network one by one. This will help identify the specific device that is causing the loop. After disconnecting each device, observe the network's behavior and monitor for any changes.
Addressing this network loop promptly will help restore stable network performance and prevent further disruptions. We would also suggest you refer to our official article - Network Loops - Link (hyperlinked).
In case the problem continues, please provide the following information:
1. Also, confirm if wired clients also lose internet connectivity.
2. Ensure that UDR is placed at a well-ventilated place.
