Network Connection

There are two methods for network connection. One is Ethernet and the other is WIFI.

Ethernet Connection

You can use a network cable (one end connected to the external network port or route) to connect your ROCK 3 to the network. The ROCK 3 will automatically configure the network for your surfing on the Internet.

To test the Ethernet, we need to follow the steps:
  • Switch to super user mode by command
$ sudo su
  • Check whether the Ethernet is normal by command, ifconfig, which would show us a network card, eth0, and the Ethernet IP address. Also, use tool, ping, to connect to a normal domain.
$ ifconfig
$ ping www.baidu.com
  • If failed to connect to a normal domain, try
$ sudo dhclient eth0

WIFI Connection

When there is not a network cable for your ROCK 3 the WIFI connection is another good choice. ROCK 3 supports 2.4G/5G WIFI and Wi-Fi 6 wireless network.

To test the WIFI performance, we need to follow the steps:
  • Switch to super user mode
$ sudo su
  • Open the WIFI
$ nmcli r wifi on
  • Scan WIFI
$ nmcli dev wifi
  • Connect to WIFI network
$ nmcli dev wifi connect "wifi_name" password "wifi_password"
  • Test WIFI perpormance by tool iperf.
