我的笔记本电脑上的无线连接遇到问题Thinkpad X201。我安装了CentOs 6.5 Minimal.有线（电缆）网络运行完美。但未检测到无线。我查看了以下链接，但对我没有帮助。

通过运行ifconfig -a我看不到wlan0，尽管我通过NetWork Managerin设置了无线Gnome。
哦，顺便说一句，我的笔记本电脑上装有 Windows7，我将其彻底清除并安装了 Linux。

通过查看您的 lspci -v 输出，我假设“Intel Corporation Centrino Wireless-N 1000”是您的无线适配器。
您能否检查下页中提到的固件是否有帮助？
http://www.intel.com/support/wireless/wlan/sb/CS-034398.htm
英特尔®迅驰®无线-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 模块已安装在您的 lsmod 输出中。但不确定版本是否正确。另外，如果您的内核早于 2.6.30，我想它可能无法工作。
