4.3. Power Connection
Connect the power adapter to the DC Input port (9-48V) on the front panel and plug it into a power source.
4.4. Carrier APN Information
Correct APN settings are crucial for cellular connectivity. Configure these in the router's web interface:
- AT&T APN: broadband
- Verizon APN: vzwinternet (Confirmed compatible since July 2024)
- T-Mobile APN: fast.t-mobile.com
If you experience connectivity issues, confirm the correct APN settings with your carrier, especially if your SIM card has static IP provisioning or requires specific APNs.
4.5. Mounting Options
The IOT-R32L router supports both DIN Rail and Wall Mount installations.

- DIN Rail Mount: Attach the provided DIN-rail mounting bracket to the router and secure it onto a standard DIN rail.
- Wall Mount: Use the screw bag and mounting holes on the router to secure it directly to a wall or flat surface.
5. Operation
5.1. Initial Access to Web Interface
- Connect your computer to the router via an Ethernet cable to either LAN1/WAN or LAN2 port, or connect to the router's Wi-Fi network (SSID: SSID_XXXXXX, where XXXXXX is the last six digits of the router's MAC address).
- Open a web browser and enter the default IP address: 192.168.1.1
- Log in using the default credentials: Username: admin, Password: password. It is highly recommended to change the default password immediately after the first login.
5.2. Checking Online Status
After configuring your SIM card and APN settings, navigate to the "Status > Cellular" page in the web interface. If connected correctly, the status will show "Connected" and display the IP address assigned to the router.
5.3. Wi-Fi Functionality
The router supports IEEE 802.11b/g/n Wi-Fi standards and can operate in both Access Point (AP) and Client modes. It provides a Wi-Fi hotspot from both cellular and wired network connections.
5.4. Automatic Failover
The IOT-R32L ensures highly reliable connectivity through automatic failover. It can seamlessly switch between local LAN, cellular, and Wi-Fi networks based on configurable priority settings, maintaining continuous internet access.

8. Troubleshooting
This section addresses common issues you might encounter. For more detailed troubleshooting, please refer to the full User Manual PDF available for download.
- No Cellular Connectivity / "Registration Denied":
- Ensure SIM cards are correctly inserted and are the appropriate 2FF Standard size.
- Verify that the APN settings in the router's web interface match those provided by your cellular carrier (refer to section 4.4).
- Check the cellular signal strength indicators on the router. If signal is weak, consider relocating the router or using external antennas.
- Confirm with your carrier that the SIM card is active and provisioned for use in a router (not locked to a phone or other device). Some carriers may restrict data usage or require specific plans for router devices.
- If the IMEI is locked, contact your carrier for assistance in unlocking it or confirming compatibility.
- No Internet Access via Wi-Fi/LAN:
- Ensure the router has active cellular or WAN connectivity.
- Check network cable connections for LAN.
- Verify Wi-Fi settings (SSID, password) on your connecting device.
- Confirm that your device is obtaining an IP address from the router (DHCP).
- Router Unresponsive:
- Check the power connection and ensure the Power LED is on.
- If the router is unresponsive, perform a hard reboot by disconnecting and reconnecting the power.
- If issues persist, use the reset button to restore factory default settings (this will erase all configurations).
