补丁说明

我刚买了一台 HP Pavilion g6 笔记本电脑，并在 Windows 7 的同时安装了 Natty Narwhal。在 Windows 7 中，我的 WiFi 运行正常，但在 Ubuntu 中，它绝对（无论我做什么）都无法检测到我的家庭 WiFi 网络。

以下是“lspci”的输出：

当前 Natty 内核不直接支持 RT5390PCIe。

您将需要下载一些驱动程序源代码并修补 Natty 内核。

不幸的是，您需要注意，每次更新 Natty 内核时，您都需要重复以下说明：

  1. 从以下网址下载 Linux 驱动程序 (RT5390PCIe)雷凌。

  2. 解压。文件将被解压到 2010_1216_RT5390_LinuxSTA_V2.4.0.4_WiFiBTCombo_DPO 文件夹。

  3. 下载除 x64_86 补丁之外的所有补丁（假设您有 32 位系统），请访问openSUSE网站。

  4. 将补丁复制到文件夹 - 2010_1216_RT5390_LinuxSTA_V2.4.0.4_WiFiBTCombo_DPO

  5. 转到文件夹。

  6. 在 /os/linux/config.mk 文件中进行以下更改 - HAS_ANTENNA_DIVERSITY_SUPPORT=y（最初为 n）

  7. 现在在终端中运行以下命令：

为此需要连接到互联网。您是否已经进入系统->管理->硬件驱动程序并查看是否列出了 WiFi（如果没有列出）。我为您找到了制造商的网站和驱动程序。 http://www.ralinktech.com/en/04_support/support.php?sn=501 您的 WiFi 卡是 RT5390PCIeaka Ralink corp. Device 5390希望这会有所帮助！
