When I use the Network Manager Command Line Tool nmcli, I get the following, which indicates that nmcli has wifi enabled, but that it cannot see any wifi connections:

[root@localhost ~]# nmcli general status STATE CONNECTIVITY WIFI-HW WIFI WWAN-HW WWAN disconnected none enabled enabled enabled enabled [root@localhost ~]# nmcli connection show NAME UUID TYPE DEVICE [root@localhost ~]# nmcli device status DEVICE TYPE STATE CONNECTION eno1 ethernet unmanaged -- lo loopback unmanaged -- wlp3s0 wifi unmanaged --

[root@localhost network-scripts]# firewall-cmd --list-all public (default, active) interfaces: eno1 sources: services: dhcpv6-client ssh ports: masquerade: no forward-ports: icmp-blocks: rich rules:
