What do the LED lights mean on the Telstra Smart Modem Gen 3

The Smart Modem Gen 3 is Telstra's newest Smart Modem, bringing the latest hybrid technology to your home broadband and allowing you to:

• Upgraded Wi-Fi:

  Telstra Smart Modem 3 has next-gen Wi-Fi 6 technology to let you connect many more devices at greater speeds. It’s perfect for today’s busy homes:

  Stream on up to 12 devices at once
  Up to 4 times more Wi-Fi capacity
  Up to 60% faster than our previous modem
  Longer battery life for your connected devices

• Connect sooner - Get online even before your home broadband is activated with your Telstra Smart Modem Gen 3. Its inbuilt, pre-activated SIM can connect to Telstra's mobile network right out of the box.

• Have a built-in backup plan - No home broadband due to network upgrades or bad weather? Your Telstra Smart Modem Gen 3 will automatically switch to Telstra's mobile network if required, so you’ll be back online in minutes, as long as 4G coverage is available.
  Mobile speeds are limited to 6/1 Mbps and will vary with local conditions and content. You can put in your own Telstra full size data sim to get uncapped speeds.
