can you use an ethernet USB adapter from my phone to my xbox series s for a wired internet...

in theory yes, but please be aware that you're responsible for any data charges it might occur.

I cannot guarantee success, but I don't see why it wouldn't work unless your provider specifically blocked such things

It depends on your phone. The Samsung Galaxy series has a USB-C to Ethernet adapter you can get.

Are you not able to run an ethernet cable from you wireless adapter to your xbox? You said you are using a usb adapter with a usb cable. I don't believe that will work (if I'm understanding what you said). If you have a wireless adapter that has an ethernet connection, you can run an ethernet cable from the adapter to the xbox.

I have used a wireless adapter to connect my xbox for years without no issue. What I use has an ethernet connection on the adapter and then I run an ethernet cable to my xbox.

This is what I'm using:

you cannot use USB to replicate any of the ports on the Xbox, not network ports, HDMI ports, nothing. USB is strictly designed for peripherals and data transfer on Xbox

Hello Kingston. I'm Arturo, a community user like you, and I'll be glad to provide assistance with your inquiry today.

If you're referring to sharing your phone's internet through a USB connector on your Xbox, it will not work.

If it's not that, I found a slightly similar thread from another user that claimed it can work. However, they used a PC between the phone and the Xbox.

Additionally, as the thread is not recent and as you want to do a direct connection between the phone and the Xbox, it may or may not work.

Not only that, but what I can recommend, is connecting your Xbox to your phone via wireless hotspot instead of getting this USB to Ethernet adapter.

Regards,

Arturo.
