Network Connection

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

Ethernet Connection

ROCK Pi E provides dual ethernets. You can use two network cables at the same time to connect your ROCK Pi E to the network. The ROCK Pi E 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 two network cards, eth0 and eth1, and the Ethernet IP address. Also, use tool, ping, to connect to a normal domain.

 $ ifconfig
 $ ping -I eth0 www.baidu.com
 $ ping -I eth1 www.baidu.com

WiFi Connection

When there is not a network cable for your ROCK Pi E the WIFI connection is another good choice. ROCK Pi E supports 2.4G/5G WiFi 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.
