使用 CentOs 6.5 的 Lenovo ThinkPad X201 無法使用無線功能

  • September 4, 2014

我的Thinkpad X201筆記型電腦上的無線連接有問題。我安裝了CentOs 6.5 Minimal. 有線（有線）網際網路完美執行。但是沒有檢測到無線。我查看了以下連結，但對我沒有幫助。

通過執行ifconfig -a我看不到wlan0，儘管我通過NetWork Managerin設置了無線Gnome。

哦，順便說一句，我的筆記型電腦上裝有 Windows7，我將其完全清除並安裝了 Linux。

通過查看您的 lspci -v 輸出，我假設“Intel Corporation Centrino Wireless-N 1000”是您的無線適配器。

您能否檢查下頁面中提到的韌體是否有幫助？

http://www.intel.com/support/wireless/wlan/sb/CS-034398.htm

英特爾® 迅馳® Wireless-N 1000 3.2+ iwlwifi-1000-ucode-39.31.5.1.tgz 2.6.30+ iwlwifi-1000-ucode-128.50.3.1.tgz

我看到 iwlwifi 模組已經安裝在您的 lsmod 輸出中。但不確定它是否是正確的版本。此外，如果您的核心早於 2.6.30，我想它可能無法正常工作。
