Let’s connect SugarPixel+ to WiFi.

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.
Both 2.4 GHz and 5 GHz networks are supported.
1

Select your network

Tap your network name from the list. If it doesn’t appear, tap Enter Manually to type it in.
2

Enter your password

Type your WiFi password and tap Connect.
3

Confirm connection

SugarPixel+ verifies the connection. Once connected, it appears in your saved networks list.
Enterprise networks are common at schools, universities, hospitals, and workplaces. SugarPixel+ auto-detects these networks and displays an Identity, Domain, and password field.
1

Try your email and password

Enter your full email address in the Identity field, leave Domain blank, and enter your password. Tap Connect.
2

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
3

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.
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.
1

Select the network

Tap the network name. A sign-in window will open automatically.
2

Complete the sign-in

Accept the terms or log in as required. When you see a success message, close the window.
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 (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.
A mobile hotspot works like a standard WiFi network.
1

Turn on your hotspot

Enable the personal hotspot on your phone or tablet.
2

Select the hotspot

Tap the hotspot’s name in SugarPixel+‘s network list.
3

Enter the hotspot password

Type the hotspot password and tap Connect.
Hotspot connections use your mobile data plan. Monitor usage if you’re on a limited plan.
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.

​
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
  • 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).
