I am having some sort of problem with the wi-fi connection: I currently live in France and my provider is Orange. I have optic fibre connection and the speed is incredibly high: approximately 47 Mbps symmetrical. If I plug in the ethernet cable, then it gets ridiculously faster, but this is not the point. Sometimes, without a pattern I can identify, the speed of wi-fi connection decreases a lot, going from 47-48 Mbps to 10-12 Mbps and even lower.
Anyone has any idea about what's happening and what I can do to fix it?
