linux下无线驱动问题，找不到无线网卡
来源: 互联网 发布时间：2016-12-14
本文导语: 笔记本电脑 thinkpad t420s，之前安装fedora15，无线网卡运行完全正常，fedora15使用内核为 vmlinuz-2.6.38.8-35.fc15.i686.PAE 换用centos 6, 因为内核过，显卡、有线网卡、无线网卡都不工作，使用fedota15内核 vmlinuz-2.6.38.8-35.fc15.i...
笔记本电脑 thinkpad t420s，之前安装fedora15，无线网卡运行完全正常，fedora15使用内核为 vmlinuz-2.6.38.8-35.fc15.i686.PAE
换用centos 6, 因为内核过，显卡、有线网卡、无线网卡都不工作，使用fedota15内核 vmlinuz-2.6.38.8-35.fc15.i686.PAE，显卡与有线网卡工作正常，但无线网卡还是找不到。
自己编译2.6.39.3版本的内核，还是一样，找不到无线网卡。
机器上的无线指示灯不亮，蓝牙灯亮并工作正常（机器侧边无线开关是打开的）
查看dmesg，部分如下，其中有一行[ 12.821160] rtlwifi: wireless switch is off，不知是否哪里有问题，请老大们帮忙看看，谢谢～～

换用centos 6, 因为内核过，显卡、有线网卡、无线网卡都不工作，使用fedota15内核 vmlinuz-2.6.38.8-35.fc15.i686.PAE，显卡与有线网卡工作正常，但无线网卡还是找不到。
自己编译2.6.39.3版本的内核，还是一样，找不到无线网卡。
机器上的无线指示灯不亮，蓝牙灯亮并工作正常（机器侧边无线开关是打开的）
查看dmesg，部分如下，其中有一行[ 12.821160] rtlwifi: wireless switch is off，不知是否哪里有问题，请老大们帮忙看看，谢谢～～
