CentOS7은 lsmod를 사용하지만 nmcli를 사용하여 Wi-Fi 장치를 찾았습니다.

lsmodCentOS 7에서 커널을 버전 4.10으로 업데이트한 후 이 명령(rtl8188eu)을 사용하여 무선 장치를 찾을 수 있습니다.

# uname -r
4.10.2-1.el7.elrepo.x86_64

# lsmod | grep 8188
r8188eu               425984  0
cfg80211              593920  1 r8188eu

nmcli하지만 AP를 사용하거나 AP에 연결하여 찾을 수 없습니다.

# nmcli d
DEVICE      TYPE      STATE      CONNECTION 
virbr0      bridge    connected  virbr0     
enp0s25     ethernet  connected  enp0s25    
lo          loopback  unmanaged  --         
virbr0-nic  tun       unmanaged  --       

이 문제를 어떻게 해결할 수 있나요?
