Sorry to read that your Xbox One is keeps on disconnecting through the wireless network.
Looking at your connection, the upstream power levels are too high and as it can cause an impact on your connection, I would like to arrange an engineer appointment to check this for you. I've sent you a PM (purple envelope icon, right corner) with some details for you to confirm please. Once you have replied I can go ahead with the appointment.
In the meantime, have you tried through a wired connection to see if that helps?
