Will Xbox One be able to connect to 802.1x?

802.1x authentication is not supported on the Xbox.

You might be able to use Internet Connection Sharing through your Mac, but I've never done this w/ OS X machines.
support.microsoft.com/.../978618 shows how to do it with PCs, so I'd do a web search for "Connect Xbox 360 through Mac"

Greetings tylerth!

What seems to be the problem is that you're trying to connect your console to a
802.1X network, which is an authentication
mechanism that acts like a door bouncer. without the proper username and password you won't be able to come in.

The problem with 802.1X authentication and it's relationship with the Xbox 360' network adapter is that the latter doesn't support 802.1X. Meaning, you won't be able to authenticate your console, as your computer, to gain access to your college network and
to the Internet-at-large.

The following suggestions can sort this out.

There're a numerous of solution to work your way around this.

1. Connect your console to your computer and share your computer's Internet Connection (ICS).
   Here's how!
   
2. You can use your computer's MAC address, that has connectivity to your college network and is registered on your college network, and have your computer's physical address in use, as your console's alternative MAC address.
   Here's how!
   
3. Contact your college IT department and ask them politely if they can registered your console's MAC address.
   

Keep us posted!

The Xbox One support WPA, WPA2, and WEP. There's nothing in the support documentation about WPA2-Enterprise and 802.1X authentication.

I know others in universities have used their laptops to connect to their universities networks and then used the MAC Address from the laptop connection on the Xbox 360. This should be possible with the Xbox One as well by adjusting the alternative MAC Address
and replacing it with another already connected device like a laptop.

Yes! Xbox Live works with the PPPoA encapsulation protocol.

If I guess what BobMcFly is referring to, it would be the IEEE 802.1x Network Access Control (NAC), which require a user to supply username and password for the authentication process flow. The Xbox One, nor the 360, are not configured for use in an 802.1x-based
network, without having to work-around this process.

This has been an ongoing issue since February last year, where users who has to work their way around the IEEE 802.1X authentication method (not supported by the Xbox One) by using a "spoofed" MAC address, can't use their console to connect to multiplayer
sessions.
