🌐 APN configuration for 4G/LTE - notes & instructions

❓ What is the APN?

The APN (Access Point Name) is the gateway through which your device connects to your mobile provider's network.
A correctly configured APN is essential for a stable and reliable mobile internet connection.

⚠️ Why is the APN Important?

An incorrectly configured or outdated APN can lead to the following issues:

• No connection to the mobile network

• Network registration failures

• Gateway crashes

• Continuous modem reboots

🆕 APN Configuration Starting from Firmware Version 21.11

From version 21.11 onward, you can manage the APN directly via the gateway’s web interface:

1. Navigate to Status → Modem Status

2. Ensure a SIM card is inserted and connected to the mobile network (roaming is also supported)

3. Enter the correct APN provided by your mobile network operator

🧼 Common Configuration Issues

In some cases, default factory-set APNs (e.g. telstra.internet) may be preloaded.
These must be manually removed or overwritten to establish a proper connection.

✅ Recommended APN Settings for Major German Providers

* Note: 1&1 uses either the Vodafone or Telefónica network, depending on the plan. Please verify which network applies to your SIM card.

💡 Additional Tips

• Check signal strength: A signal better than –105 dBm is recommended

• Restart required: After changing APN settings, reboot the gateway to apply changes

• Roaming: If you're abroad, ensure data roaming is enabled and the APN is correctly configured

If problems persist, please contact your mobile provider’s customer service or reach out to our support team for assistance.
