I'm trying to use a wireless USB key on a RHEL7 NUC. The adapter shows up in 'ifconfig':
eno1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.0.21 netmask 255.255.255.0 broadcast 192.168.0.255

ether 00:14:d1:d8:cc:0f txqueuelen 1000 (Ethernet)
...
but there is no wireless configuration options available in NetworkManager, so I'm not able to select an SSID/wpa2-password and so forth.
I found a thread that discussed a similar issue for centos. Following advice there, it appeared that I did not have the kernel module loaded for the wireless adapter:
# lspci -nn | grep -i net

However after following the advice in that thread for restarting the NetworkManager:
# service network stop
# service wpa_supplicant stop
# chkconfig --level 12345 network off
# chkconfig --level 12345 wpa_supplicant off
# chkconfig --level 2345 NetworkManager on
# service NetworkManager restart
there are no still no wireless configuration options showing in NetworkManager. I do have the NetworkManager-wifi package installed:
# rpm -qa | grep NetworkM

What else do I need to do to make the wifi adapter available to NetworkManager. Or, perhaps simpler, how can I configure the wireless adapter on the command line?
