Minimal home WiFi/wired router @ Orange Pi RV2 SBC

Fast and simple way to make your Orange Pi RV2 SBC device as a home WiFi and wired router running on Irradium OS (based on CRUX distribution), in few steps. Fully functional, secure by default, and suitable for internet exposure.

Installation

1. Prepare image by single command:

   ./build.sh

   Alternatively, you can customize your SSID and WiFi password as:

   WIFI_SSID="MyRouter" WIFI_PASSWORD="SuperSecret!" ./build.sh

2. Format 16GB+ SD Card and burn image generated above by next one-liner:

   mintstick -m format && mintstick -m iso -i irradium-opi-router.img && sync

3. Insert SD Card into SBC.

   Connect your computer to the left from top Ethernet port (eth1, LAN: 192.168.10.1).

   Connect your ISP modem to the right from top Ethernet port (eth0, WAN).

   Power on.

4. Wired clients require static IP configuration.

   On your host configure DHCP manually.

   • Under Network Manager:

     • Method: Manual,
     • Address: 192.168.10.10,
     • Netmask: 24,
     • Gateway: 192.168.10.1,
     • DNS: 192.168.10.1,8.8.8.8.

   • Or, just from CLI (my example below):

   sudo ip addr add 192.168.10.10/24 dev enp130s0         # set static IP in LAN subnet
   sudo ip route add default via 192.168.10.1             # set SBC as a default gateway
   echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf  # set DNS

   WiFi clients receive IP, gateway, and DNS automatically via DHCP.

5. Now you can always SSH to your new Orange Pi RV2 router from host box without password (key-only auth):

   ssh [email protected]

6. Auto-login without password with using minicom and USB-to-Serial converter (PL2303):

   sudo minicom --baudrate 115200 --device /dev/ttyUSB0

   Done!
