My Xbox One S keeps connecting and disconnecting from the Internet

Hello, first it's a pleasure to be able to help you today.

My name is welcome to the community.

Hello Josh, your console is connected by Wi-Fi or cable, if you are over Wi-Fi try, make sure that the two modem/router frequencies are active (2.4 & 5ghz) and the channels are on automatic, they usually come on automatic but can be configured manually and this may be causing the signal outage to your console.

My xbox one s just disconnects from the internet multiple times per day

After trying many things I have found out my Xbox One only keeps shutting down when it is connected to the internet, if I plug in the internet cable or connect using wi-fi it will shut almost immediately, but when it is disconnected from the internet it
will stay on all day....weird.

i have 2 Xboxs in my house and they run on the internet fine until a laptop or iPad starts to access the internet, if your internet connection is below 5mb/s this may be the problem, try playing on Xbox LIVE with all iPod touches/ Laptops/ computers/ and
all other internet connected devices turned off, or disconnected from the internet.

Let's try to power cycle your console. Please hold down the power button on the front of the console for approximately 15 seconds until the power light shuts off. Wait about 60 seconds, then power it back on. Be sure you see the green "XBOX ONE" animation
loading screen when you power it back up. check network settings and then try to play hope this resolve you're problem.
