Hallo zusammen,

seit 2 Tagen ist mein Glasfaser-Anschluss für Echtzeitanwendungen (Gaming, Discord, etc.) leider nicht mehr nutzbar. Ich habe periodische Ping-Spikes (teilweise bis ~1000 ms). Vorher hat alles gut funktioniert. Das Problem tritt auf allen Geräten auf. Ich habe schon versucht das Modem und den Router zu reseten, ohne Erfolg. Bei der Fehlerbehandlung über die Website wird auch ein Problem erkannt und das Modem neu gestartet, bringt allerdings nichts. Ich habe auch versucht das jeweilige Test Gerät über speedport.ip zu priorisieren, auch das ohne Erfolg. 

Hier noch ein entsprechender Test über das Terminal am MacBook:
