Hello, i will write in English since my German is bad. We are facing big issues with our internet. Every day, 20 times throughout the day, internet completely stops working. Wifi works, but internet stops working (I can still ping the gateway IP, but i cannot ping google.com). It lasts 2-5min, then it comes back. This is a big problem, it is cumulative around 45-90min of offline status daily.

I have provided few images of working/not working comparison: ping, gateway status on http://192.168.2.1/html/login/status.html?lang=en, and image of the router

Firmware version 010137.4.6.001.2
Router Serial Number: 90100000000J022017182

P.S.
We are not owners of the apartment, the internet is registered to our landlord.
