WiFi Gateway Configured with Wrong Network or Password

When configuring your Wi-Fi Gateway, the device will accept any credentials provided and attempt a connection. If you provide an incorrect network or password, the Gateway will not be able to connect to the Amper system. This article will provide guidance on resolving incorrect credentials depending on the status of the Gateway.

Gateway Not Connected to Network

If a Gateway is unable to make a connection with the provided network credentials, the Gateway's LED will show blue (Attempting Connection) for about 5 minutes then change to White/Light Purple (Wi-Fi Configuration Mode) and then repeat the cycle.

When the Gateway is in Wi-Fi Configuration Mode (White/Light Purple LED), the device's 3 letter code will show up in your list of Wi-Fi networks, ready to be reconfigured. Run the standard Wi-Fi configuration process found in our article below to reconfigure the Gateway with the correct 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.

Gateway Connected to Incorrect Network (With Outside Internet Access)

If your Gateway is connected to one of your networks (the device will show a Green/Yellow/Red LED representing signal strength) that allows outside internet access, we will be able to clear the device's credentials and allow you to reconfigure the Gateway.

Send an email to support@amper.xyz with the 3 letter name of the Gateway(s) along with a request to clear the credentials.

Gateway Connected to Incorrect Network (Without Outside Internet Access)

If your Gateway is connected to one of your networks (the device will show a Green/Yellow/Red LED representing signal strength) but the network blocks all outside communication, then Amper will be unable to wipe the device's credentials.

In this event, you will need to take one of two actions:

  1. Move the Gateway outside of the range of the configured network. This will prevent the Gateway from connecting to the currently configured network and after 5 minutes of not connecting to the currently configured network, will enter Wi-Fi Configuration Mode. You will now be able to re-configure the gateway.
  2. Resolve any IT Configuration issues preventing connection of the Gateway to Amper's system. This will allow you to either use the currently configured network or provide Amper connection to the device so we can wipe the device's credentials remotely.
