4. Installation and Setup
Follow these steps to install the RTL8822CE Wireless NIC into your compatible device:
- Prepare Your Device: Ensure your device (e.g., Jetson Xavier NX, Jetson Orin NX/Nano) is powered off and disconnected from any power source.
- Locate M.2 Slot: Identify the NGFF (M.2 A/E Key) slot on your device's motherboard or expansion board. Refer to your device's manual for exact location.
- Insert the Module: Gently insert the RTL8822CE module into the M.2 slot at an angle. Once seated, press down the module and secure it with the screw (if provided by your device's motherboard).
- Connect IPEX Cables: Carefully connect the IPEX connectors of the provided cables to the corresponding Main and Aux ports on the RTL8822CE module. These are small, delicate connectors, so apply gentle, even pressure.
- Attach Antennas: Route the SMA ends of the cables to an appropriate location on your device's chassis or an antenna bracket. Screw the two antennas onto the SMA connectors. Ensure they are finger-tight.
- Power On: Once the installation is complete, reassemble your device if necessary, connect the power, and power it on.
- Driver Installation: For Windows 10/11, drivers are often automatically detected. For Linux systems, you may need to install specific drivers. Refer to the Realtek RTL8822CE driver documentation for your specific Linux distribution.
