问：如何安装wifi驱动？

Answer 1

您的 WiFi 卡显然是这样的：

03:00.0 Network controller [0280]: Intel Corporation Centrino Wireless-N 1030 [Rainbow Peak] [8086:008a] (rev 34)

它由iwlwifi包含在标准内核包中的驱动程序支持。自内核版本 2.6.36 起，您的适配器就支持这种方式。对于某些内核，驱动程序模块可能会被命名iwlagn。

您需要的是适配器的固件文件。在 Debian 9 中，如果您在安装 Debian 时没有启用它，您首先需要启用 Debian 存储库的非自由部分。（这里的非免费意味着“你没有得到它的源代码”，而不是“你必须为此付费”。）

然后firmware-iwlwifi使用您最喜欢的包管理实用程序安装包，然后重新启动，驱动程序应该会自动加载并准备好使用。
