- Wi-Fi Connection Tips

Helpful tips for setting up and maintaining a stable Wi-Fi connection so your turfRad sensor uploads reliably.

Wi-Fi Network Requirements

If you install a sensor please keep the following two things ready: 

  • SSID

  • Password (if secured)

With those two things you should be normally all set. But just for completeness, we have listed here the full requirements and best practices for your WIFI to make sure it works seemlessly with turfRad:

 

Wi-Fi & RF

  • 2.4 GHz Wi-Fi required

  • 802.11 b/g/n, 20 MHz channel width recommended.

  • SSID must allow 2.4 GHz clients (no 5 GHz-only SSIDs).

Network Type

Supported:

  • Open (no password)

  • WPA2-Personal (PSK/AES) (recommended)

Not supported:

  • Captive portals / browser-based logins (terms pages, vouchers, SMS login, proxies)

  • WPA2-Enterprise / 802.1X

  • WPA3-only (WPA2/WPA3 mixed mode is OK)

IP & DHCP

  • DHCP required (automatic IP assignment).

  • Network must provide gateway and DNS.

 

Required Internet Access

Firewall must allow outbound:

  • DNS: UDP/TCP 53

  • Time sync (NTP): UDP 123

  • Secure cloud communication: TCP 443

  • IoT hub/update server (MQTT over TLS): TCP 8883

The Network must allow direct Internet access immediately after joining (no “unlock” via browser).

Network Policies

  • Disable client/AP isolation, or ensure the sensor can reach gateway, DNS, and Internet.

  • Avoid HTTPS inspection / TLS interception.

  • Avoid aggressive DNS or firewall filtering that blocks unknown IoT devices.

  • Your IT team can allow access by whitelisting the sensor’s MAC address, found in the Sensor Status tab of the turfRad mobile app.

Coverage

  • Recommended signal strength at install location: ≥ −67 dBm (minimum −75 dBm).

  • For outdoor installs, ensure adequate AP placement and antenna clearance.


 

Here is how you can check the WIFI (and MAC address) in the Sensor Status Tab:

If you do not have a strong WiFi signal accessible in your facility, we can:

  1. Offer a WiFi hotspot that operates over a cellular signal, providing a strong and
    reliable connection for turfRad to upload data.
  2. Suggest a third-party LTE hotspot that can provide plenty of data for turfRad and likely get delivered very quickly.
