我是 Ubuntu 新手。我今天安装了它，但我遇到的第一件事就是我只能通过 wifi 连接到互联网。有人能帮我吗？
iwconfig 结果：
eth0 no wireless extensions.
lo no wireless extensions.

相同的无线芯片（和非常相似的笔记本电脑）；无线功能在 Trusty 和 Vivid 中都无法开箱即用；我一直都是这样安装的：
- 从以下位置下载无线芯片的驱动程序这里；
- Ctrl使用++打开Alt终端T；
- 跑步
cd ~/Downloads; unzip MT7630E-release.zip; cd MT7630E-release; sudo bash install
如果驱动程序安装到 UEFI 管理系统，则应在 UEFI 设置中禁用安全启动以加载模块。
