Wi-Fi & Cloud Connectivity Troubleshoot

Wi-Fi Connectivity Troubleshoot

If Atmocube is unable to establish a Wi-Fi connection, the Wi-Fi indicator on the device will change to a solid red color.

Here is a list of initial troubleshooting steps to take if Atmocube is unable to establish a Wi-Fi connection:

  • Ensure the Wi-Fi router is in proximity for Atmocube to receive a strong signal.
  • Verify the entered Wi-Fi network name and password are accurate and ensure that you haven’t changed the Wi-Fi network name and password.
  • Reboot your Wi-Fi router. Press the power button or unplug the power cord to your router. Then, turn the router back on or plug it back into the electrical outlet and wait 30 seconds.
  • Review Atmocube Wi-Fi requirements and verify whether your Wi-Fi network fulfills these by checking your network configuration:

Frequency: Atmocube supports connection to 2.4 GHz Wi-Fi networks. Atmocube will not discover or connect to 5GHz networks.

Channel: Atmocube does not support connection to Wi-Fi networks on channels 12, 13, and 14.

Encryption methods: Atmocube supports Wi-Fi networks with WPA/WPA2/WPA3 encryption and unencrypted Wi-Fi networks. Connection to hidden Wi-Fi networks is supported via the Atmocube Wi-Fi setup app by manually entering the Wi-Fi credentials. WPA-Enterprise encrypted Wi-Fi networks are not supported.

  • If the network uses static IP addressing instead of DHCP, the Atmocube configuration tool should be used to set up the network connection.
  • MAC Address Whitelisting 

Some corporate networks may require two-factor authentication, login portals, captive portals, splash pages, or managed login networks. It may be possible to establish a connection on these kinds of networks by adding Atmocube's MAC address to your network's whitelist. A sticker with the MAC address (listed as Device ID on the device) is attached to the back of the Atmocube. To locate the Device ID, check out this page.

Cloud Connectivity Troubleshoot

If Atmocube is connected to Wi-Fi but cannot connect to the cloud server, the Wi-Fi indicator will be flashing red.

When experiencing cloud connectivity issues, start by checking the status of the Atmocube servers here.

Atmocube domains, ports, and servers

In order to give you access to your sensor data via the mobile app, dashboard, and APIs, as well as to keep devices up to date with the most recent bug fixes, Atmocube devices communicate with a number of our backend services. The advanced network settings may be restricting access to some of our backend services in case you have cloud connectivity issues. Make sure the network allows outgoing connections to all of the following domains and their associated IP addresses/ports:

Service Details Details and Ports
MQTT Messaging Service ; port 8883 
OTA Services ; port 443, ; port 443

NTP Servers,,, ; port 123

Cloud connectivity issues can be diagnosed by checking if these domains and IP addresses are accessible by pinging the domains and ports listed above from the network that you are trying to connect Atmocube to. It is possible that the network firewall is configured in such a way that it blocks outgoing connections to the listed domains and ports. You may try adjusting your firewall’s policies to allow Atmocube to establish connections on the domains and ports listed above. 

When attempting to connect Atmocube to the cloud via an enterprise network with firewall protection, please verify whether your firewall vendor’s advanced URL filtering and categorization rules allow connections to the domains listed above.  

To check the status of the Atmocube cloud services and verify if any of them are experiencing downtime, visit the webpage following the link:

Checking for Network Compatibility

A quick test can be performed to determine if Atmocube’s connection issues are rooted in the advanced configuration of your WI-Fi network by setting up a 2.4 GHz mobile hotspot using your smartphone and trying to connect Atmocube to the Wi-Fi network created by the smartphone.

If the issue persists after attempting the steps above, please contact us for support with the following information to help us determine the issue:

  • The Wi-Fi router's make and model.
  • Provide your Atmocube device ID and serial number (on the back of the device).
