我已在我的 CentOS 6.5 盒子中添加了一个 wifi 适配器，但我无法在ifconfig输出中看到它。
dmesg 输出中的无线适配器
[root@testldap log]# dmesg | grep -i netgear
usb 1-1: Product: NETGEAR A6200 WiFi Adapter
usb 1-1: Manufacturer: NETGEAR
[root@testldap log]#
Linux版本
[root@testldap log]# cat /etc/redhat-release
CentOS release 6.5 (Final)
nmcli 输出
[root@testldap log]# nmcli nm
RUNNING STATE WIFI-HARDWARE WIFI WWAN-HARDWARE WWAN
running disconnected enabled enabled enabled enabled
[root@testldap log]#
ifconfig 输出（如您所见没有 wifi 接口）
[root@testldap log]# ifconfig -a
