Sorry I'm having to write in English my German is not that good yet. I have taken a new connection with Vodafone (GIGA DSL 16). My connection has started from 05.12.2022.
There are no problems with browsing, streaming video etc. But I am having severe issues with audio/video calls on all platforms: Teams, Messenger, Whatsapp, my work VOIP phone etc. Also since I work from home I connect to my office VPN and use remote desktop. I have severe stuttering on remote desktop as well.
My previous internet provider was Deutsch Telekom. I used it for 2 years. I never had such issues with A/V calls and remote desktop. The line was also the same 16Mbits DSL. I really hope someone from Vodafone will be able to assist me in this regard as I am facing lots of difficulties in my work, I cannot listen to meetings properly because of lag/voice cut off/stuttering and remote desktop stutters so much it is impossible to work. As I mentioned before these issues are happening with the new connection, these did not happen before at all. Will appreciate some swift assistance in this regard.
