Xbox one randomly disconnects with controller but the internet is still running

When i'm playing a game, in a party with friends, or just browsing my Xbox one, my controller will suddenly disconnect and at the same time my Xbox one disconnects from XBOX LIVE. This always happens often. I've tried the following things:

• Factory Reset
• Used automatic settings in the Network Settings
• Updated my Xbox One Controller
• I have reset my Router and Modem a lot and still doesn't fix it.
• I have tried using a different WIFI by going to my friend's house, and I still disconnect out of no where.
  
• I have tried using LIVE SUPPORT and none of it helps....
• Tried wired connection

Is this just happening to me or is this happening to anyone else out there? Is there a possible way to FIX this problem!

THIS ALSO NEVER HAPPENED ON MY XBOX 360

Controller desyncing and Xbox Live disconnecting.

My Xbox One has been repeatedly desyncing my controller and then ~5 seconds later my console will disconnect from Xbox Live. If I'm in a part I can still hear every one clearly through the TV until it disconnects from Xbox Live. The controller will eventually
reconnect to the console and the console will reconnect to the internet. The problem occurs randomly. Does anyone know how to remedy the issue?

 

Controller/Internet disconnection

Just recently my controller has started to randomly disconnect from my Xbox, at the same time my Xbox disconnects from the internet. It seems to do better while plugged into Ethernet cable and the controller connected via usb; but, it stills happens. I noticed
the issue was blowing up 3 years ago but I never found useful information to help fix the problem. Thanks.
