Joining the Wired Network

In the summer of 2021, the College upgraded its wired and wireless network and replaced BNCWifi with BrasenoseWifi. This upgrade came with several improvements including:

  • One secure wireless key to connect all your wireless devices to the network.
  • Personal VLANs: all devices you join to the Brasenose network are part of your own personal, secure private network and can communicate with each other – just like your network at home.
  • Devices such as wireless printers, games consoles and smart devices (e.g. Amazon Echo) can now be easily connected to the network.
  • The ability to add wired devices that do not have a built-in web browser (e.g. some printers and games consoles) to the network.

This guide contains details of how to onboard your devices to the Brasenose wired network – please read through the instructions carefully and follow all steps in the relevant section before requesting IT support. 

Before getting started you will need to know the MAC (hardware) address of the wired network adapter. Details of how to find the hardware address on some common devices can be found at the bottom of this page.

One you have found the MAC (hardware) address of your device, you can either:

a) Use any internet-enabled device to navigate to – Once the page has loaded, continue to Step 1 of this guide.


b) Connect the device you wish to register to an ethernet port – these are available in every student and academic room as well as the College libraries. If choosing this option, the device must have a web browser. When you open your web browser you will be automatically redirected to the onboarding page. If you are not redirected straight away, please try navigating to any website (e.g. and you will be redirected to the onboarding portal. Continue to Step 1 below.

Step 1

Read and agree to the Terms & Conditions and then click Start:

First page of the Brasenose network onboarding process

Step 2

On the next page, select University of Oxford Single Sign On:

Onboarding step 2 - selection of authentication method

Step 3

You’ll be prompted to enter your SSO username on the next screen. Please enter your username in the format where abcd1234 is your Oxford SSO username:

Onboarding step 3 - entering SSO username

Click Next and enter your password – this is the same password you use to log into your University email account. Next, click Sign in and authorise any prompts you receive for multi-factor authentication (MFA).

If you receive your MFA prompt via a push notification from the Microsoft Authenticator app you may need to open the app for the notification to appear.

Onboarding step 3 - entering SSO password

Step 4

Once you’ve logged in successfully you will be given the option to set up a wifi connection or a wired connection. Select Wired connection:

Wifi or wired network selection menuStep 5

The next screen allows you to enter the unique MAC address of your device. Guidance on how to find your wired MAC address for Windows, MacOS, PS4 and Xbox One can be found below.

For other devices, please consult the user manual for your device (user manuals are generally available online – Google “[device make and model] user manual”.

MAC Address submission form

Click Continue after entering the MAC address and you will see a message confirming that your device has been successfully registered.

Step 6

Finally, if the device you have just registered is already plugged in via ethernet, you must disconnect the cable from the device and then plug it back in again to connect successfully.

Once your device is registered on the wired network it will be part of the same secure, personal network as any other devices you have registered on the Brasenose network, whether you’re connecting from a student room or a reading area in the College libraries.


Joining the Brasenose wired network if your device does not have a built-in web browser

If you have a device which uses a wired connection but has no built-in web browser, such as some models of printer, you can use another device such as a phone or laptop to register it using its wired MAC (hardware) address.

The MAC address for many devices is located on the underside or back of the device. Otherwise, you can consult the user manuals for your device online – Google “[device make and model] user manual”.

Once you have found the wired hardware address for your device, simply connect a wireless-enabled device to the BNC-Onboarding network and follow the instructions for joining the wired network using option B. Don’t forget to disconnect and reconnect the device to the network after you have registered it.

How to find the wired MAC (hardware) address on commonly used platforms

Operating Systems

Windows 10

Open your Start menu and start typing Ethernet Settings. You will see the Ethernet Settings menu appear as a suggestion. Click on it to open the settings menu:

On the next screen under the ethernet heading, select your ethernet adapter:

At the bottom of this menu under Properties you will see Physical address (MAC) – this is the address you need to enter into the onboarding portal.


Go to the Apple menu > System Preferences > Network (under “Internet and Wireless”).

Make sure the ethernet interface is selected on the left side.

Click on the Advanced button on the right, and then the Hardware tab. The MAC address is listed there.

Game Consoles

PlayStation 4

Go to Settings in the main menu (looks like a toolbox).

Scroll down and select System. Then select System Information.

Here you will see the MAC addresses for LAN (Ethernet) and Wi-Fi.
