![无法连接到 802.1x,尽管 DHCP 没有设置 IPv4](https://linux22.com/image/1079252/%E6%97%A0%E6%B3%95%E8%BF%9E%E6%8E%A5%E5%88%B0%20802.1x%EF%BC%8C%E5%B0%BD%E7%AE%A1%20DHCP%20%E6%B2%A1%E6%9C%89%E8%AE%BE%E7%BD%AE%20IPv4.png)
有人可以帮我设置我的互联网吗?
我全新安装了 Ubuntu 12.04 LTS。安装之前,我可以用笔记本连接互联网。
我必须使用 802.1x 来连接。
我不知道该怎么办了。
不知何故,我没有列出 IPv4,这可能是问题所在,但为什么会出现这种情况,在 Linux Mint 13 上安装之前它也有效?
