Additional Network Ports for Multiplayer Gaming: Connecting problems

Additional Network Ports for Multiplayer Gaming: Connecting problems
Recently I started experiencing some struggles with my xbox. My online games lag and my xbox struggles connecting with internet. Most of the time I play Fifa and when I was playing fifa online the game started lagging. Also my xbox suddenly logs me in and
out automatically. It's now been going for a few months. I checked my internet connection and there is nothing wrong with it. All other devices have optimal wifi.

Maybe someone knows what is the possible problem and could help me? I tried a lot (resetting the xbox, resetting wifi connection) but nothing works. But I want to be sure my xbox is just broke before I order a new one.

Thank you in advance!
