Hello,For months I have had the problem that my internet connection keeps dropping out. At first I thought it was due to the WiFi, but I made the effort to connect my MacBook directly to the router via a LAN cable and ran a ping test for several minutes.The disconnects and latency spikes occur approx every 20-120sec. Even the direct connection to the Sagemcom F5359 router shows connection interruptions. I'm new to the Netherlands and desperately looking for a service line to report this problem. Where can I report this problem?What i tried:1. Take off the Powersupply of Fiber optic box and router for 10 min (No changes)2. Reconfigure everything and disconnect all other devices like TV, Playstation ect.
