How to Update ALTA Gateway Firmware

Keeping your ALTA Gateway’s firmware updated is essential to resolving unexpected issues. Firmware updates for Ethernet and cellular or IoT Gateways are available periodically through iMonnit.

To update a gateway’s firmware, it must communicate with iMonnit. A gateway can’t be updated locally or through iMonnit Enterprise/Express or Monnit Mine. This article shows you how to update gateway firmware.

Update Gateway Firmware

Updating a gateway’s firmware may reset its configurations to default settings. If your gateway is programmed with a static IP address, this may clear it out and reenable the Dynamic Host Configuration Protocol (DHCP). You should prepare to reconfigure the gateway on a network with DHCP enabled if you perform an update on a gateway with a static IP address.

Likewise, if you are using a Monnit 3G or 2G Cellular Gateway with a custom APN, this APN will need to be resent to the gateway as per the steps at the following link:

This applies to the ALTA Ethernet Gateway 3, 2G, and 3G Cellular Gateways with firmware up to version and Ethernet Gateway 4 firmware earlier than The 3G Cellular Gateway with firmware version and later and Ethernet Gateway 4 with firmware version and later won’t lose configurations during the update procedure.

  1. Log into iMonnit as an administrator.
  2. Click Gateways in the left-hand sidebar menu.
  • If an update is available, you will see a download arrow icon by Gateways.
  1. Click the download arrow icon to see the gateways to update.
  2. If you only want to update a few gateways, click on them, then click Update Selected.
  • The green check mark indicates you’ve selected the gateway(s).
  • The update will only install for the gateway(s) you’ve selected.
  1. If you’re updating all the gateways, click Update All without clicking every gateway.
  • The gateway’s firmware will update to the most recent version. Updates generally take less than 10 minutes, and the gateway will check in normally after the update.

If you have multiple gateways, the download arrow may take longer to appear as the system verifies the status of all your gateways.

You will see many consecutive Gateway Management messages under the gateway’s History because the gateway is processing the firmware update.

After the firmware update, you should see Data messages reported as usual.
