实在没辙了，centos如何启用无线网络？谢谢各位大侠了

iwconfig

在这儿回吧～
1.rfkill list，看看输出是不是
Soft blocked: no
Hard blocked: no
2.ifconfig XXX up
3.连wifi
我是用: wpa_supplicant -B -D wext -i XXXX -c <config_file>
config_file 是 wpa_passphrase 生成的
4.dhclient XXXX

驱动会不会有问题，看你描述，好像网卡射频模块的发射功能没开

来看看

broadcom的驱动，centos7.0自带。之前版本需要自己去官网下载。话说你的是什么版本！broadcom的网卡就是坑，以后记得买电脑不要买broadcom网卡的
