WiFi Gateway Not Connected to System

If your machine is only showing a "Lost" or "Off" state when you expect to see production, your Gateway may  not be connected to our system. This article will help you identify the root cause and resolution for Gateway related issues.

Diagnosing Gateway Lights

The first step to getting your gateway connected to our system is by examining the top LED on the front of the device. This LED will help provide guidance on the actions needed to resolve your connectivity issues.

Gateway is connected to local network as shown by the green LED.

Gateway is in Wi-Fi Configuration mode as shown by the white/light purple LED.

LED Off

Gateway is not powered on.

  • Make sure that the power supply cable is securely plugged into the Gateway and a reliable power source.
  • If the gateway is still not powered on, try connecting a different power supply that is known to work. If the gateway is now on, there is an issue with the original power supply and it will need to be replaced.
    • If your gateway is still not powering on, please email support@amper.xyz with the subject line "Broken Gateway" and include the Gateway's 3 letter code along with the steps you have taken to reach this determination in the body of the message.

White/Purple LED 

Gateway is in Configuration Mode and will need to have the credentials for your local network entered.

  • See our articles below for more information on entering your network credentials.

    • If opting for Wi-Fi devices, there are a few steps your IT team will need to take to ensure our devices can properly connect to your network.

    IT Setup Configuration

    Amper Gateway Configuration

    In order to connect Amper Gateways, your network will need to be configured for the following:

    • Network must be 2.4 GHz (Our devices do not support 5GHz-only networks).
    • Supported network types are WPA2 (most common), WPA, WEP, and Unsecured/Open. Devices do not support WPA-2 Enterprise.
    • Hidden SSID networks are not supported for 2nd Generation Devices (with the button).
    • Amper Gateways do NOT support networks that require a captive portal log-in (such as a guest network that requires logging in).
    • Amper Gateways require DHCP and do not support static IP assignment.
    • All device connections are outbound but devices both send and receive data on each connection.
    • You may need to ensure that the below ports and domains are properly allowed through both DNS filtering and any NAT settings.
    • TCP Ports Open (Outbound Connections)
      • 1883
      • 8883
      • 5683
    • UDP Ports Open (Outbound Connections)
      • 5684
    • Domains Open (Outbound Connections) - note that DNS domain filtering must use DNS group filtering not single-host DNS filtering
      • device.spark.io
      • device.nodes.spark.io
      • device.udp.particle.io
      • device.tcp.particle.io
      • a1z2vcintpz3vi-ats.iot.us-west-2.amazonaws.com
    • Device MAC Addresses White Listed
      • If your network restricts access to unknown devices by MAC Address, contact support@amper.xyz to obtain your device Device MAC Addresses to provide to your Network Administrator.

    Web & Tablet App Access

    In order to fully access Amper’s web and tablet app, your network must be configured for the following:

    • TCP Ports Open (Outbound Traffic)
      • 443
      • 80
    • Domains Open (Outbound Traffic)
      • *amper.xyz
      • sentry.io
      • *looker.com
      • *.lookercdn.com

    If any of the above information seems confusing or daunting, do not worry! These are standard IT configurations that your factory's IT team will be familiar with. For requirements & recommendations related to the Gateway configuration process, please also see the article below.

Blue LED

Gateway cannot connect to your Wi-Fi network.

  • If this is the first time configuring your Gateway, you may have selected the wrong network or entered the password incorrectly. Try running the configuration process again to ensure the credentials were entered properly.
    • Note: If the Gateway is unable to connect with the provided credentials, the LED will cycle between Wi-Fi configuration mode (white/light purple LED) and trying to connect (blue LED).
  • Your network may be blocking the device from making a connection with the Gateway. Please check with your IT team to see if you are using MAC Address Filtering which will prevent unknown devices from making any connection. If you are in need of your devices' MAC Addresses, send an email to support@amper.xyz with the subject line "MAC Address Request" and include the three letter code on the front of the devices you need MAC Addresses for.
  • The gateway may lack the required reception to maintain a connection to our network. Please see our article Improving Gateway Reception for help on improving your device's connection.
  • The Access Point(s) are not able to handle the number of concurrent connections.
  • The network may be hitting DHCP limits for the number of devices connected.
  • The Access Point(s) may intermittently go down interrupting connection.

Red LED

Gateway may lack the required reception strength to maintain a connection to our network.

Green or Yellow LED

Gateway is connected to your local network with acceptable strength

  • If your Gateway is showing as connected to your local network, the issue may lie with a different component of our hardware. Please see our articles Aggregator Not Connected and Sensor Not Collecting Signals for guidance on checking the other hardware components.
  • Verify that your IT team has implemented the appropriate configuration changes so our devices can communicate with our system. Please provide your IT Team our article below to verify the configuration steps have been taken.

For More Information

Check out to the Hardware Module in your Settings to review when the gateway became disconnected. You can also remotely evaluate your gateway signal strength and see if the aggregator is connected.

Gateway Connectivity in the Hardware Module

You can see the gateway is connected to our system by looking at the "GW Connected" column. It will take one of the following values:

  1. Connected

The gateway is currently connected to our system and is shown by the Green check mark.

image
  1. Disconnected (Less than 30 days)

If a gateway has been disconnected for less than 30 days, you will see the red circle and the date/time the device was last connected to our system.

image
  1. Disconnected (More than 30 days)

If a gateway has been disconnected for more than 30 days you will see the yellow triangle icon along with with last connected date/time.

Use the "Get Stats" Button to Check Signal Strength

image

For more detailed information on the current state of the devices, you can press the "Get Stats" button. This will populate the "GW Signal Strength" and "GW Has Aggregator" columns if the device is connected to our system and we are able to retrieve the current state of the device.

‼️
Note: If the Gateway is not connected, the "GW Signal Strength" and "GW Has Aggregator" columns will NOT populate.
image

GW Signal Strength

The "GW Signal Strength" will populate with Strong, Moderate, or Weak that represents the strength of the connection. If you see the gateway showing a Weak signal then you may need to adjust the position of the gateway to achieve a stronger signal.

GW Has Aggregator

The "GW Has Aggregator" column will show if an aggregator is properly connected to the gateway.

‼️
Note "GW Has Aggregator" showing Connected does not mean that the sensors are properly connected or connected at all. This value only represents the connection of the Gateway and Aggregator through the CAT5 cable.

Example

Hitting the "Get Stats" button will also refresh the "GW Connected" and "GW Last Connected" values which can be useful for monitoring the status of the gateway as you work to resolve any issues with a specific gateway.

  1. Okuma #2 shows as disconnected.
    2. image
  2. Do work to connect the gateway and click "Get Stats". Gateway is now showing as connected with a strong signal, but Aggregator is not.
    3. image
  3. Plug in Aggregator and click "Get Stats". Aggregator is connected.

If Issue Continues to Persist

If you have tried all of the above options but are still unable to resolve your issues, please email support@amper.xyz with the subject line "Amper Gateway Issues" and include the device name, color of the light, and the steps already taken to resolve the issue in the body of the message.
