WiFi 5 GHz is not stable on Vodafone cable router


I have a cable internet subscription from Vodafone for 2 years now. 5 GHz WiFi connection for more than one year.

As the two WiFi frequncy bands 2.4 and 5GHz are enabled on the router, I could only depend on 2.4 for stable connection, the 5GHz only works for a few days and then all 5GHz connections,

What I've tried so far to fix the issue:

  • Restarting the router 
  • Changing channel frequency
  • Changing wifi SSID name
  • Resetting the router settings
  • Changing router location
  • Inspecting the wifi on different client devices (My mobile, the TV, my laptop, ..etc)
  • Moving to a new house Smiley (fröhlich)

But nothing worked. I have no issues with the internet connection neither the 2.4 GHz wifi. 

I tried to call the hotline and the whatsapp group, but could not get to anyone who speaks English. I want to change the router I think the problem could be related to the router itself.
