4. Installation Guide
Hardware
- Interface Compatibility
- Only supports M.2 Key E slot (commonly found in ultrabooks or industrial PCs).
- Ensure the motherboard supports both PCIe x1 (Wi-Fi) and USB 2.0 (Bluetooth) signals.
- Antenna
- Use dual-band antennas (2.4GHz/5GHz) and connect them securely via IPEX connectors.
- Avoid contact between the antenna and metal components to prevent signal degradation.
