XBOX ONE RANDOMLY DISCONNECTING! PLEASE HELP!

The Issue:

Ever since i've moved my Xbox One from my basement to my room, my Xbox keeps randomly disconnecting from xbox live every 30-60 minutes. An example of this would be me playing Call of Duty Zombies with a friend and the game would disconnect me with the error
message "You have been disconnected from the Blacks Ops 3 servers." and the party im in would completely stop, displaying the message "Something has gone wrong with your party." After this happens, I am able to connect back to xbox live almost immediately
and join my party back. This is very annoying as i always lose progress in an online game I'm playing.

What I've Tried so Far:

I have gone on the offical xbox support page for this issue and have tried almost everything there. First i had to check if my connection is strong enough, and a 30mbps DL/30mbps UL/55ms ping byfar exceeds the suggested amounts. I have an **** TM802 modem
connected to a Optimum Sagemcom 5260CV which is then connected to a 2.4 GHz extender which was initially around 15 feet from my Xbox. Next I attempted to remove any interference. I have no wireless headphones and my wifi connection passes straight through
a wooden wall, and I also have 0% packet loss. Next i tried to reset my modem, router, extender, and Xbox but with no luck. Finally I have tried moving the extender right near my Xbox and connecting via ethernet cable, yet I still have the same issue.

Conclusion:

I have tried almost everything possible and I don't know what to do next. Please try and help me, it will be very much appreciated. Thank you for your time!
