在 Linux 中更改無線適配器驅動程序

我正在使用 openSUSE Tumbleweed。我買了一個新的 PCI-E 無線網卡，它支持 5G WiFi（英特爾 5100 AGN）。它沒有出現在lspci中 ，即使我取出舊適配器，它仍然看不到我的新適配器。我曾嘗試在 BIOS 中將其關閉再打開，但沒有任何幫助。必鬚根據韌體文件夾安裝驅動程序

如何讓核心使用我的新適配器代替舊適配器或與舊適配器一起使用？

您的筆記型電腦有 BIOS 白名單，而 Intel 5100 不在其中

我建議打電話給聯想並從他們那裡訂購一個 5 Ghz 的英特爾 wifi 卡，它可以與 X220 一起使用，作為使用消除白名單的版本更新 BIOS 的選項，這可能會使筆記型電腦無用。

我發現 X220 和迅馳 Wireless-N 1000 的維護手冊一定是它製作時使用的卡，並且它在維護手冊的列表中，所以這就是它起作用的原因

請參閱第 114 頁和第 115 頁的http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/0a60739.pdf，它顯示了可以工作的 wifi 卡。列出了 Intel 6205 和 6300，但 6300 可能需要 3 個天線。我仍然建議從聯想訂購，因為白名單可能正在尋找卡的一種變體，而從 ebay 購買的卡可能仍然無法使用
