笔记本装上centos系统连不上无线,桌面右上角没有出现wifi图标

1.查询可用的无线网卡,发现什么都没有
[root@localhost ~]# iw dev

2.还以为是需要重新装无线网卡驱动,结果从下面链接中找到了解决办法

解决方法
  删除/lib/firmware/ath10k/QCA9377/hw1.0目录下的firmware-6.bin

3.[root@localhost ~]# iw dev
phy#0

ssid Ann_YT_DP

4.查看无线网卡连接情况
[root@localhost ~]# iw wlp2s0 link

5.查看所有可用的无线网络信号
[root@localhost ~]# iw wlp2s0 scan | grep SSID
SSID: Ann_YT_DP
SSID: Ann_YT_DP

tips:
启用无线卡
[root@localhost ~]# ip link set wls1 up
