WiFi and Bluetooth Connection Guide

Hardware Preparation

1. Ensure you have the following accessories:
   • Wireless Module with M.2 E Key (e.g. Intel AX211)
   • 2.4G/5G Dual-frequency Antenna with IPEX4
2. Hardware Installation Steps:
   • Properly insert the wireless module into the M.2 E key slot on the board.
   • Connect the antenna to the corresponding port on the wireless module (usually marked as MAIN and AUX).
   • Ensure the antenna connections are secure.

2.4G/5G WiFi Connection Setup

1. After starting the Windows OS, it will automatically recognize the wireless module.
2. Click on the network icon at the bottom right corner of the taskbar.
3. In the network list that appears, select the WiFi network you wish to connect to. Both 2.4G and 5G networks are supported and can be used as needed. Generally:
   • 2.4 GHz network: Suitable for longer distance connections with better wall penetration.
   • 5 GHz network: Suitable for high-speed connections at close range, supporting higher data transfer rates.
4. Enter the network password.
5. Click “Connect” to complete the WiFi connection.

Bluetooth Connection Setup

1. Click on the Bluetooth icon at the bottom right corner of the taskbar.
2. Ensure Bluetooth is enabled (if not, click the “Bluetooth” switch to turn it on).

5. Put the Bluetooth device you want to connect in pairing mode.
6. In the list of available devices displayed, select your device.
7. Follow the on-screen instructions to complete the pairing process.

Precautions

1. Ensure the antennas are installed correctly and securely, or it may affect signal quality.
2. After the first installation, OS may take a few minutes to install necessary drivers. If installation is unsuccessful, manually download and install drivers from the wireless module manufacturer’s official website.
3. If interference occurs when using 2.4 GHz WiFi and Bluetooth, it is recommended to adjust the wireless router’s channel settings.

FAQ

Q:	A:
Can not boot up	1. LattePanda Sigma does not have onboard storage devices. Please ensure that the hard disks are installed. 2. Check again that the power adapter is tightly connected, and the input voltage is within the required range. 3. Try disconnecting the power for a few seconds, then connect it and turn on the device again.
Suddenly shuts down or restarts while running	Ensure that the power of the power adapter is not less than 90W. Otherwise, LattePanda Sigma will suddenly shut down or restart due to insufficient power supply.
Blue LED doesn’t tun off	Wait few minutes, and confirm the auto power on function in BlOS is disabled.
No screen output	1. Re-tight the display cable and wait few minutes until the system start completely. 2.Confirm the voltage of RTC battery is enough. Low voltage or no battery will cause the operating system to take too long to boot. 3. If there is no screen when using a Type C display, Pls find an HDMI display to test.

Cooling fan doesn’t start:

1. The default setting is that the fan automatically starts when the temperature reaches the startup threshold.
2. Check the BlOS Fan settings and change the cooling fan temperature setting.

Access BIOS setup:
