Eu pude encontrar meu dispositivo sem fio (rtl8188eu) usando o comando lsmod
após atualizar o kernel para a versão 4.10 no CentOS 7
# uname -r
4.10.2-1.el7.elrepo.x86_64
# lsmod | grep 8188
r8188eu 425984 0
cfg80211 593920 1 r8188eu
Mas não consegui encontrá-lo usando nmcli
ou conectar-me ao meu AP
# nmcli d
DEVICE TYPE STATE CONNECTION
virbr0 bridge connected virbr0
enp0s25 ethernet connected enp0s25
lo loopback unmanaged --
virbr0-nic tun unmanaged --
Como posso resolver este problema?
############## após a atualização 20170317
saída do comando "ip link", o dispositivo pode ser encontrado:
