报告站长，openSUSE上不了网了，似乎重装也不行

[xqzyxb]

事发是我重装了主机的W系统，然后在中文页上能找到的是说改为桥接，但这个方法完全超过我的能力。我一直是用的网络地址转换NAT连接。现在全局中的网络里"网络地址转换NAT"这个选项下面的界面名称栏是灰色的，改为"NAT网络"，界面名称：未指定。点击里面没有选项。改为"桥接网卡"，界面名称：Intel(R) Ethernet Connettion I217-V.

我在读了也是白读的网上看到，说这个是没有网卡，我就扣脑壳了，这个没得网卡，导入的其它W系统可以上网。如果是这个原因，我重装openSUSE是否还是上不了网。

能开机的话你就可以在 TW 客户机里看看是不是有网卡硬件（网络控制器，Ethernet controller 或者 Network controller）。例如，

sudo lspci -vnn

我记得那个 NAT 是需要在安装的时候就配置启用的，然后在「网络 Network」的适配器标签页里面还需要看看「高级」区域（默认是没有展开的吧）里面的网卡类型是否有选以及线缆是不是连接了。安装的时候 TW 系统就会自动配置了。

现在可以上网了

[lonelicloud]

哈，原来是客户机系统的网络配置没有设置好

[xqzyxb]

我不知道问题在哪，我是按站长给的sudo lspci -vnn 用这个搜了后，再从里面的内容再搜，搜出来的一大堆，然后就像在迷宫里乱转，乱试出来了。

[lonelicloud]

你的探索精神非常棒

[xqzyxb]

报告站长，您给我的表扬使我无地自容，不过万恶地辨证法告诉我，探索能力是动物的本能，我又可以苟且。
