network spikes

Hello, I know this topic has already been mentioned but since they are a bit old I allow myself to create a new post. Since today my game has become unplayable because of a network peak (seen on the f1 command) I have a good configuration and a good network the problem does not come from there (I tested all the tips mentioned in the other topics). I have not seen a solution that worked nor a response from a moderator so I ask whoever wants to hear it if someone has a solution or if I have decided that I am not worthy.
