After a power cut (happens quite frequently in the area) my internet connection is unstable.
Streaming and consistent connections are fine but browsing the internet or using (mobile) apps is very unstable both via WiFi or cable. Sometimes a page loads fine then the next one shows text only and images don't load.
Also I regularly need to reload a page before it loads at all.
I've verified this happens on my own WiFi equipment as well as the built-in WiFi of the modem.
My laptop is connected via cable and loading websites is unstable there as well.
One of my bank apps even refuses to start unless I turn WiFi off on my phone.
I've tried rebooting several times and reconnecting the fiber cable between wall box and modem but this doesn't change anything. Also specifying custom DNS doesn't resolve the issue.
Below the status of the router. I don't see any logs I can check.
Should I schedule a technical visit or is there something else I can do?
