Ethernet
5B Ethernet
ROCK 5B is equipped with one 2.5G Ethernet port. You can use a network cable (one end connected to the external network port or route) to connect your ROCK 5B to the network. The ROCK 5B will automatically configure the network for your surfing on the Internet.
Ethernet throughput test result table.
| Direction | Bitrate |
|---|---|
| Upstream | 2.34 Gbits/sec |
| Downstream | 2.35 Gbits/sec |
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 or enP4p65s0 , 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 or $ sudo dhclient enP4p65s0
