CentOS 7 Hotspot Setup

This applies to the Hotspot setting in CentOS 7’s Gnome 3 desktop > System Tools > Settings > Network > Wi-Fi Hotspot:

In terminal get root access and

nano /etc/sysconfig/network-scripts/ifcfg-Hotspot

HWADDR=???
ESSID=”???”
SSID_HIDDEN=yes
MODE=Ap
TYPE=Wireless
BOOTPROTO=shared
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
NAME=Hotspot
UUID=??
ONBOOT=yes
KEY_MGMT=WPA-PSK
WPA_ALLOW_WPA=no
WPA_ALLOW_WPA2=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_PRIVACY=no

Adjust ???.  This is not complete.  DNS customization doesn’t stick.  WPA2 key is same as root user’s password.  But it gets the Hotspot working and changes from WEP to WPA2.
