How to set up OneCast for Xbox with your iPhone Yes, I even used the app while I was two rooms away from the Xbox itself. Connecting through a LAN will make the connection stronger, but I have about a 30mps connection speed to my phone through wifi, and only 45mps to my Xbox with little to no issues. Speaking of connection, if you have a decent router and reliable mps to your internet, you should be just fine to only use the wifi options as opposed to the recommended LAN connection. This is to avoid the 'Xbox has been disconnected' error that will pop up when you've lost connection.
Aside from this, you want to make sure you also stay close to your router if you're using wifi, and close to your Xbox if you're using the controllers.
