🛠 Configure a reliable WiFi 6 network with BPI-RT2
Objectives
This tutorial aims to configure the Banana Pi BPI-RT2 as the main router for a home network. You will learn to connect cables, access the interface, and enable WiFi 6. It is an ideal project for starting with modern networks.
Required Materials
- Banana Pi BPI-RT2 board
- 12V DC power adapter (barrel jack connector)
- RJ45 Ethernet cable (for WAN connection)
- Computer or smartphone for configuration
- Additional Ethernet cables for LAN ports if needed
Steps
- Physical Connection: Plug the 12V adapter into the barrel jack port. Connect your internet box to the WAN port (often distinct from LAN ports). If you have a PC, connect it to one of the three LAN ports.
- First Boot: Wait 30 seconds for the system to start. LEDs indicate network activity. OpenWrt firmware is pre-installed.
- Interface Access: On your LAN-connected PC, open a web browser. Type the default IP address (usually 192.168.1.1). If access fails, check the address via
arp -acommand in a terminal. - Wireless Configuration: In the web interface, go to the "Network" tab then "Wireless". Enable 2.4 GHz and 5 GHz bands. The AX3000 module supports 2x2 MIMO.
- Security: Set a strong WiFi password. Choose WPA3 encryption if available, otherwise WPA2. Save settings.
Verification
Connect a WiFi 6 compatible smartphone. Verify it connects to the 5 GHz band for optimal speeds. Run a speed test to confirm stability. Check that the four antennas are properly screwed in for maximum coverage.
Going Further
Explore the GPIO headers to add sensors. Check the source code on GitHub to customize the Realtek BSP. Note that OpenWrt 22.03 is old; consider an update if support allows.
