Streaming TV Issue (English)

Hello all. 

I apologize for not speaking French, so the message will be in English. 

I am having an Orange Internet 1000 Mbps connection since end of 2024 and I am facing a major issue with the internet connection.

More specifically, the Streaming TV I am watching, is freezing the picture every couple of minutes, even though I am connecting my streaming TV device to the Orange modem via Ethernet cable (not wifi).

I have tried 3 different devices for streaming TV and they are all giving me the same results, a freezing flow of the streaming TV, every couple of minutes. 

I have spoken to my streaming TV provider and after checking my internet connection, he came to the conclusion that the problem is the very high ping number in my intercom connection. This number is supposed to be around 10-20 and I am seeing numbers from 110 up to 300 in my internet connection.

So, clearly it's an issue of the internet connection and I am trying a whole year to find a solution to this issue, but with no luck. 

Any help with this?
