3.1 Safety Precautions
- Ensure your device is powered off and unplugged from all power sources before installation.
- Discharge any static electricity from your body by touching a grounded metal object.
- Handle the module by its edges to avoid touching sensitive components.
- Refer to your device's manual for specific instructions on accessing the M.2 slot.
3.2 Hardware Installation Steps
- Power off your computer and disconnect the power adapter and battery.
- Open the computer casing to access the internal components, specifically the M.2 slot.
- Locate an available M.2 slot (typically labeled for WWAN or 5G modules).
- Carefully align the EM9291 module with the M.2 slot's keying notch.
- Insert the module into the slot at a slight angle (approximately 30 degrees) and gently push it in until it is fully seated.
- Press the module down and secure it with the retaining screw provided by your device manufacturer.
- Connect appropriate 5G antennas to the module's antenna ports (ANT1, ANT2, etc.) if required by your device. Refer to Figure 3 for port locations.
- Close the computer casing and reconnect the power adapter and battery.

6. Troubleshooting
If you encounter issues with your EM9291 module, try the following troubleshooting steps:
6.1 No Network Connection
- Check SIM Card: Ensure the SIM card is correctly inserted and active with your cellular provider.
- Driver Installation: Verify that the correct drivers are installed and up to date. Check Device Manager (Windows) or `lsusb`/`lspci` (Linux) for the module's presence and driver status.
- Antenna Connection: Confirm that the antennas are securely connected to the module's ports.
- Network Settings: Review your operating system's cellular network settings to ensure proper configuration (APN settings, network selection).
- Module Reseat: Power off your device, open the casing, and carefully reseat the EM9291 module in its M.2 slot.
6.2 Slow Speeds
- Signal Strength: Check your signal strength. Weak signal can lead to slower speeds. Try moving to an area with better coverage.
- Network Congestion: 5G network performance can be affected by the number of users and network congestion in your area.
- Driver Issues: Ensure drivers are optimized for performance.
- Antenna Quality: Ensure you are using high-quality, 5G-compatible antennas.
6.3 Module Not Detected
- Physical Installation: Double-check that the module is fully seated in the M.2 slot and secured.
- BIOS/UEFI Settings: Some devices may require enabling the M.2 slot or WWAN functionality in the BIOS/UEFI settings.
- Compatibility: Confirm that your device's M.2 slot is compatible with WWAN/5G modules and provides the necessary PCIe lanes.
7. User Tips
- Verify Dimensions: Before purchasing, always confirm the physical dimensions of the EM9291 module (approximately 12cm x 12cm x 3cm) to ensure it fits your device's M.2 slot and internal space.
