Connecting to MIT Wifi Network

 Students can connect devices to the MIT Wi-Fi network using MIT SECURE, the primary encrypted network for the campus community. [1, 2]

How to Connect to MIT SECURE (Phones, Tablets, Laptops)

Select the Network: Choose MIT SECURE from your device's available Wi-Fi list.
Log In: Authenticate using your MIT Kerberos username and password.
Accept Certificates: If prompted to trust a security certificate or network profile, click Trust or Continue.
Onboarding Portal: If you need specific configuration help for your device type, visit the official MIT Wi-Fi Onboarding page. [1, 2, 3, 4, 5]

Alternative Campus Networks

eduroam: Students can also connect to eduroam by signing in with their full MIT email address and Kerberos password to get high-speed access across participating global research and education institutions. [1]
MIT GUEST: For short-term visitor or guest access (which lacks internal resource and printer access), connect to MIT GUEST and provide a mobile number or email address. [1, 2]
Devices Not 802.1X Compatible (e.g., smart speakers or specific gaming/IoT devices): Devices that cannot handle standard enterprise logins can use the special MIT SSID, which requires a pre-shared key (PSK) personal Wi-Fi password generated via wifi.mit.edu. [1, 2]

If you are trying to connect a specific type of device (like a smart speaker, printer, or game console) or running into an authentication error, let me know what device you're using.

Students can connect an ESP32 to the campus network by registering the device or using a dedicated lab network, as the ESP32 only supports 2.4 GHz Wi-Fi and cannot connect directly to enterprise WPA2-Enterprise/WPA3-Enterprise portal logins like MIT SECURE out of the box without special configuration. [1, 2, 3]

Options for Connecting an ESP32 at MIT

Use Course/Lab Wi-Fi Networks: If you are working in specific departmental or course lab spaces (such as EECS labs), check course documentation—some labs provide dedicated 2.4 GHz SSIDs like EECS_Labs (open) or course-specific networks like 608_24G with a local lab password. [1]
Register for Personal Credentials / Onboarding: For general campus connectivity, visit the official MIT Wi-Fi Onboarding Portal to register non-standard or personal devices and generate the proper credentials or instructions for your device class. [1, 2]
Register as a Non-Personal / DLCI Device: If the ESP32 is acting as an IoT project or sensor node, check MIT IS&T guidelines for registering specialized hardware or IoT/DLCI devices on the network rather than standard consumer sign-in flows. [1]
Use an Access Point / Phone Hotspot Alternative: If campus enterprise authentication blocks the ESP32, many students program the ESP32 in Access Point (AP) mode or use a local travel router/phone hotspot operating on 2.4 GHz to bridge the device locally. [1, 2]

Technical Requirements in Your Code

2.4 GHz Band Only: Ensure your code targets a 2.4 GHz wireless network; the ESP32 hardware does not have a 5 GHz radio.
Station Mode Initialization: Configure WiFi.mode(WIFI_STA) and pass your SSID and password into WiFi.begin(ssid, password) within your Arduino or PlatformIO sketch. [1, 2, 3]

Here is a short guide showing how to program and initialize station mode on an ESP32 using the Arduino IDE:

Yes, you can use an iPhone as a personal hotspot, but it shares your cellular data connection (4G/5G) rather than retransmitting an existing Wi-Fi network. [1, 2]

How to Turn On Personal Hotspot

Open Settings on your iPhone.
Tap Personal Hotspot (or tap Cellular, then Personal Hotspot).
Toggle on Allow Others to Join.
Note or tap the Wi-Fi Password to view or change it. [1, 2]

How to Connect Another Device

Via Wi-Fi: Open the Wi-Fi settings on your computer, tablet, or another phone, select your iPhone's name from the list of networks, and enter the password. [1]
Via USB: Plug your iPhone into a computer using a USB or USB-C cable. (On Windows, ensure you have the latest Apple Devices or iTunes installed.) [1, 2]
Via Bluetooth: Enable Bluetooth on both devices, pair them, and connect through your computer or device's Bluetooth settings. [1]
Instant Hotspot: If the connecting device is signed into the same Apple Account or part of your Family Sharing group, you can connect directly through the Wi-Fi menu without typing a password. [1]
