# WiFi

<div className="wizard-only">
  ## Let’s connect SugarPixel+ to WiFi.
</div>

SugarPixel+ supports most home networks, enterprise networks (username + password), and captive portal networks. Networks are saved automatically — like a phone — so SugarPixel+ reconnects to any previously used network without re-entering credentials. Both **2.4 GHz** and **5 GHz** networks are supported.

To manage WiFi, go to **≡ → General Settings → WiFi**. To remove a saved network, tap the **delete icon** next to its name.

<div className="cc card-sky">
  <Accordion title="Home WiFi" icon="house" description="Standard home or apartment network with a password">
    Both **2.4 GHz** and **5 GHz** networks are supported.

    <Steps>
      <Step title="Select your network">
        Tap your network name from the list. If it doesn't appear, tap **Enter Manually** to type it in.
      </Step>

      <Step title="Enter your password">
        Type your WiFi password and tap **Connect**.
      </Step>

      <Step title="Confirm connection">
        SugarPixel+ verifies the connection. Once connected, it appears in your saved networks list.
      </Step>
    </Steps>
  </Accordion>
</div>

<div className="cc card-orchid">
  <Accordion title="School / University / Work" icon="graduation-cap" description="Enterprise WiFi — requires a username and password">
    Enterprise networks are common at schools, universities, hospitals, and workplaces. SugarPixel+ auto-detects these networks and displays an Identity, Domain, and password field.

    <Steps>
      <Step title="Try your email and password">
        Enter your full email address in the **Identity** field, leave **Domain** blank, and enter your password. Tap **Connect**.
      </Step>

      <Step title="If that doesn't connect — try splitting your email">
        Some networks require the email split across two fields:

        * **Identity:** the part before the @ (e.g., `jsmith`)
        * **Domain:** the part after the @ without the @ sign (e.g., `university.edu`)
        * **Password:** your account password
      </Step>

      <Step title="If that still doesn't connect — check your institution's WiFi guide">
        Search for your school or employer's WiFi setup instructions for **Linux**, **Android**, or **Other devices**. These guides list the exact credential fields required.
      </Step>
    </Steps>
  </Accordion>
</div>

<div className="cc card-fern">
  <Accordion title="Captive Portal" icon="mug-hot" description="Hotels, cafés, airports — requires accepting terms or signing in through a browser page">
    Some networks require you to accept terms or log in before granting internet access. SugarPixel+ opens a sign-in window automatically when you connect to one of these networks.

    <Steps>
      <Step title="Select the network">
        Tap the network name. A sign-in window will open automatically.
      </Step>

      <Step title="Complete the sign-in">
        Accept the terms or log in as required. When you see a success message, close the window.
      </Step>
    </Steps>

    <Warning>
      **Portal sessions can expire:** Portal sessions can expire at any time, cutting off readings. If your session expires and you have any alerts enabled, SugarPixel+ will automatically fire a [Captive Portal alert](/sugarpixel-plus/global-alert-settings#captive-portal-alert) (found under **≡ → Global Alert Settings → System Alerts**) — this follows your global alert settings and quiet hours. An on-screen notification will also appear when the session needs to be renewed.
    </Warning>

<div className="cc card-flamingo">
  <Accordion title="Mobile Hotspot" icon="mobile-screen" description="Connect using a phone or tablet as a WiFi source">
    A mobile hotspot works like a standard WiFi network.

    <Steps>
      <Step title="Turn on your hotspot">
        Enable the personal hotspot on your phone or tablet.
      </Step>

      <Step title="Select the hotspot">
        Tap the hotspot's name in SugarPixel+'s network list.
      </Step>

      <Step title="Enter the hotspot password">
        Type the hotspot password and tap **Connect**.
      </Step>
    </Steps>

    <Info>
      Hotspot connections use your mobile data plan. Monitor usage if you're on a limited plan.

<div className="cc card-lavender">
  <Accordion title="Firewall Reference" icon="shield-halved" description="For sharing with your school or workplace IT department">
    Setup at a school or workplace usually requires IT assistance. Share the requirements below with your IT department. If they have questions, ask them to contact us at [support@customtypeone.com](mailto:support@customtypeone.com).

    ### Network Requirements

    * **2.4 GHz and 5 GHz WiFi are both supported**
    * **WPA2 (password-based) is supported**
    * **Most enterprise WiFi (username/password) is supported**
    * **Captive portals are supported**
    * SugarPixel+ does not need to be on the same WiFi as the CGM phone
    * **Custom security certificates cannot be installed** — networks that require SSL/TLS inspection or a custom root certificate will not work

    ### Firewall / Allowed Endpoints

    All connections use **HTTPS** (port 443) except time sync and remote snooze. Only the CGM in use needs to be allowed.

    * **Dexcom:** \*.dexcom.com
    * **Libre:** \*.libreview\.io
    * **Gluroo:** \*.gluroo.com
    * **Nightscout:** patient-specific URL (provide to IT)
    * **System updates:** \*.sugarpixel.com
    * **Remote snooze (from the app):** outbound ports **443**, **8883** and **8443** — only needed if you use [Remote Snooze from App](/sugarpixel-plus/snoozer)
    * **Time sync (NTP):** \*.ntp.org on port 123 — additional servers returned by NTP must also be reachable. A custom time server can be configured if needed.

    ### Notes for IT

    * This list may change as features are updated.
    * Whitelisting by **SugarPixel+ MAC address** is the most reliable long-term approach. The MAC address is shown under **≡ → General Settings → System** (also shown at the bottom of **≡ → General Settings → WiFi**).
