Hello, sorry for english but I do not speak German yet,

First few details as requested:

• Which modem/ router are you using?Vodafone Station CGA6444VF       
  
• Do you use a rental device from us or do you have your own device? rental device        
• Which error occurs? 24/7 High BufferBloat and high ping/latency, makes online gaming impossible.     
  
• How is your device connected to the modem? LAN     
• Which browser do you usually use? Chromium  
  
• Which operating system do you have on your computer? Linux/WIN11    
  
• Start andduration of the disruption: since the beginning

So since the beginning I'm having issue with high bufferload and ping which makes it impossible to play online games. I have my Gigabit LAN port connected directly to the router with CAT7 cable, I tried CAT6 cable as well but it was the same issue. I also tried using VF Station in Bridge mode to use my own router and the bufferbloat and ping was improved significantly, unfortunately my own router is having it's own issues and I can't use it, I also do not feel like connecting and even buying new device as VF should work properly.

Please help me to resolve it as I can't use internet with a latency of 500-750ms.

I see a lot of people are facing the same or similar issue:

Hi @shivv3er,

well, the line looks fine for now,- how do you measure it?

Yes it's a bit better recently but not perfect. How  I  measure?  By connecting my PC by ethernet cable to the router and making a test.

Hey @shivv3r,

thanks for the feedback, so, does it occur permanently, or just for a few minutes / seconds?

Regards

Tobias
