I have just installed CentOS 7 over an old windows PC. The CentOS 7 image was of minimal install as I had only 4 GB of pendrive available.
The wifi driver named wlp18s0b1 shows in the list if I do ip link
but it's configuration file is not there in the /etc/sysconfig/network-scritps/ so I can't enable this interface using ifup
. ifup wlp18s0b1
says the following.
/sbin/ifup: configuration for wlp18s0b1 not found.
Usage: ifup
The option nmcli d
shows the wifi device wlp18s0b1 listed along with the ethernet card but when I do nmcli conn up
it says the following .
Error: unknown connection wlp18s0b1
I am not sure how to bring this device up with nmcli
and I don't have any extra network tools such as iw, iwconfig, ifconfig, dhclient
available as it was a minimal install.
I only have access to wifi from here so can't use ethernet to install these as well.

You can quickly connect to a wireless network using
nmcli
:This will connect to the specified SSID, ask you for the passphrase, and configure the entire connection for you.
You are meant to use the literal word
wifi
, not the interface name. NetworkManager will find your WiFi interface on its own.
