Update your wifi set-up for the new year
If you use the University’s eduroam wifi on a non-Apple device, please update your wifi set-up to ensure your connection to eduroam continues uninterrupted after Monday 5 January. Simply delete or 'forget' your current eduroam wifi connection on your device, and set up eduroam again by following the instructions below.
Before you start
- Make sure you are in a location where the eduroam wireless network is available. You can setup eduroam in a location away from where the wireless network is available but this means that you will not be able to test it works.
- If you are carrying out a reinstallation of your eduroam setup we advise removing the old configuration first. To do this follow step 4 on this page.
- You must be using Windows 11 to connect to eduroam. You can have a look at Microsoft's support website for information about to check your version of Windows.
- We strongly advise upgrading to the latest Windows version that your device can support as older versions may have incompatible software or drivers and may be vulnerable to security issues. We currently support 23H2 (until Nov 2025), 24H2 and 25H2 versions of Windows 11.
Step 1: Connect to UniOfCam-Guest wifi network temporarily
You need to be online while you set up eduroam. You should connect via UniOfCam-Guest or another local wifi network if your College doesn't offer UniOfCam-Guest. Or you could use a wired connection.
Step 2: Create a network access token
Create a network access token for your Windows device. If you've connected to eduroam previously we still recommend that you create a new network access token.
You need to create a separate token for each of your devices and for each service. For example, if you want to connect to eduroam and the UIS VPN from both your laptop and phone, you need to create 4 tokens.
Use a meaningful username following the format CRSid+laptopYYYY@cam.ac.uk. It may be helpful to add the year if you've created network tokens previously. For example, ab123+laptop2024@cam.ac.uk. You will need to use lower case.
Keep the window with the new network access token open as you will need this when you are asked to enter a username and password later.
Create a new network access token on the Networks Access Token website.
Step 3: Download and install the eduroam Configuration Assistant Tool (CAT)
You can use the eduroam Configuration Assistant Tool (CAT) to walk you through the set-up process.
When it asks for a username and password, you need to enter the network access username and password that you created in the previous step. Your username should be in the format CRSid+device@cam.ac.uk, for example, abc123+laptop2024@cam.ac.uk. Some browsers can add extra spaces when you copy and paste so if your password isn't working, try typing it instead.

Step 4: Forget the UniOfCam-Guest network
You should now be connected to eduroam.
Finally, you need to forget the UniOfCam-Guest network or your local College wifi network, if used during the set-up steps. This ensures you will connect to eduroam wifi network whenever in range.
