Flash the image to a micro SD card using a disk imager, or via dd command on Linux. Once complete, insert the SD card into your Rock Pi and you're done. It will boot OpenWrt. Ethernet It might be a bit tricky to connect via Ethernet for the first time. By default the DHCP client is disabled but the IP address is configured as static 192.168.1.1 After having flashed OpenWrt like described above, you can reach the OpenWrt via Ethernet by using the IP address 192.168.1.1 Enable DHCP Another approach is to boot once, remove the SD card and edit the configuration, to enable DHCP. Edit /etc/config/network and add the following lines: config interface 'wan' option proto 'dhcp' option device 'eth0' Since you want to access it via WAN port, you also need to open the firewall. In this configuration, it could be dangerous, if it is directly accessible from outside your network! /etc/config/firewall config rule option name 'Allow-web' option src 'wan' option proto 'tcp' option dest_port '443' option target 'ACCEPT' option family 'ipv4' option enabled '1' config rule option name 'Allow-ssh' option src 'wan' option proto 'tcp' option dest_port '22' option target 'ACCEPT' option family 'ipv4' option enabled '1' Wifi It has support for dual band 2,4 / 5GHz wifi. The newer Rock Pi 4 plus versions come with an onboard uFL connector, which makes it ideal to use it with an external antenna as a wifi hotspot. The wifi module is able to be used as AP. Wifi firmware Wifi and bluetooth is provided by a AMPAK AP6256 chip. But the needed firmware (brcmfmac-firmware-43456) is currently not included in OpenWrt.
