CSAILPrivate

On October 15th, we have made improvements to our wireless network for better security and user experience. The new system offers:

Our previous “CSAILPrivate” network used Kerberos authentication, which can be complex to configure, especially for Apple devices. Additionally, the underlying RADIUS protocol has known security vulnerabilities.

To address these issues, we have transitioned to a new wireless authentication system provided by Cisco Meraki. This system uses a more secure authentication method and simplifies the connection process.

Before you can connect to the network, you must first create your CSAILPrivate wireless account

CSAILPrivate

CSAILPrivate is CSAIL’s encrypted, authenticated wireless network. Use of CSAILPrivate is required to get a static IP address or to print to CSAIL printers when connected to a wireless network. As a reminder, although your traffic over the wireless network will be encrypted, there are still other points within the CSAIL network and outside CSAIL where your traffic can be monitored, albeit with a slightly higher degree of difficulty. The instructions below describe how to set up access using a Meraki username and password.

Create a wireless account

Before you can connect to CSAILPrivate, you must create an account

  1. Visit my.csail.mit.edu
  2. Login using your CSAIL Kerberos account
  3. Go to “My Account”
  4. Under “Manage WiFi Password” click “Change” to Set or Change your CSAIL WiFi password.
  5. You will be given the option of a randomly generated password.
    • Click the copy button then save to your password manager.
  6. Click “Save” to submit and save your password
  7. If you would rather create your own password, deselect the “use generated password” checkbox.
  8. Enter a unique, strong password, and click “Save” to submit.
    • Be sure to remember or save in your password manager!
