Xbox One shared connections issues

Hey there Adace1!

Sorry to hear about the connection issue. Do you mean Internet Connection Sharing? Follow each step in our

Internet Connection Sharing Troubleshooter to set up a shared internet connection on the Xbox One console.

Post back and let us know if that helps!

You need to share the connection that is connected to the Internet and then when choosing which adapter you want to share it to, choose the one that is connected to the Xbox, not the internet.

Shared networks will always have.mtu issues there isnt much you can do without access to the router

Also connecting to a pc to provide internet access will.always cause mtu issues its too slow runing a non paid vpn will not provide you with a very fast speeds

You should reduce the amount of connections

You have to find your IP and setup ICS correctly

It isnt just a.matter of sharing a connection

Please.follow.the.guide.above

Open see if you have Full Cone NAT on that router as well or are you going to notice performance issues when you are connected. This is going to cause a lot of issues if your neighbor is using a PS3 or Xbox 360 and even a Wii trying to share that same NAT.
Me and my brother sharing a Router with a NAT that wasn't Full Cone, I turned it over to Full Cone allowing more than one DNS Connection through the Gateway.

I had the same problem... but i have use a hub for share my pc connection. Now i can go to the xbox live.
