更改 Linux 中的无线适配器驱动程序

我正在使用 openSUSE Tumbleweed。我购买了新的 PCI-E 无线卡，支持 5G WiFi（Intel 5100 AGN）。它没有出现在lspci 即使我取出旧适配器，它仍然看不到我的新适配器。我尝试在 BIOS 中将其关闭然后再次打开，但没有任何帮助。必须根据固件文件夹安装驱动程序

如何使内核使用新适配器或与旧适配器一起使用？

答案1

您的笔记本电脑有 BIOS 白名单，但 Intel 5100 不在其中

我建议致电 Lenovo 并从他们那里订购一块 5 Ghz 的 Intel wifi 卡，该卡可与 X220 配合使用，因为可以选择使用消除白名单的版本来更新 BIOS，这可能会使笔记本电脑变得无用。

我找到了 X220 和 Centrino Wireless-N 1000 的维护手册，肯定是它所用的卡，并且它在维护手册的列表中，所以这就是它工作的原因

看http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/0a60739.pdf第 114 和 115 页显示了可用的 wifi 卡。 Intel 6205 和 6300 均已列出，但 6300 可能需要 3 个天线。我仍然建议从 Lenovo 订购，因为白名单可能正在寻找该卡的一种变体，而从 eBay 购买的一款可能仍然无法使用

答案2

您应该查看日志或中是否有相关消息dmesg

寻找像这样的行missing firmware file xxxx/xxxx

在此输入图像描述

（由于我手头没有Linux机器，所以这只是网上找到的示例）

然后您就会知道要下载哪个文件。
