Beaglebone 无法使用以太网线连接到互联网

我一直在尝试使用直接插入 Netgear 路由器的以太网电缆让 Beaglebone Black 连接到互联网。我尝试了很多事情，但到目前为止没有任何效果。

以下是一些相关输出。

# Today after reflashing beaglebone, internet still not working

我不知道如何解决这个问题。昨天当我开始写这个问题时它开始工作，然后它开始神秘地工作。我今天早上重新启动后，它又不起作用了。

答案1

转到/etc/network/interfaces然后添加：

auto eth0
iface eth0 inet static
    address 192.168.0.100 # or whatever static IP you want
    netmask 255.255.255.0
    gateway 192.168.0.1

重新启动后，Beaglebone 可以成功 ping Google。
