In this tutorial I will show you how to install WiFi drivers in Linux Mint. Install driver for WiFi adapters. When you install Linux Mint on a desktop or laptop with a WiFi adapter there is a chance that this adapter is not being recognized during the installation process. 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. If your wireless card has not been detected automatically by the RHEL 8 / CentOS 8 kernel you can search for it first in the repositories. Do a $ sudo dnf search wireless and you will be presented with a list of wireless drivers. Most of the drivers you will find in the official RHEL 8 / CentOS 8 repositories are for Intel cards. This is the main source of Documentation for the Linux wireless (IEEE-802.11) subsystem. This wiki features information for end-users, developers and vendors. This site covers all the new 802.11 drivers, the new core mac80211 and cfg80211 components along with the new userspace and in-kernel nl80211 configuration interface.

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.
Shrewsoft failed to attach to key daemon windows 10. The other name for the key daemon is IKED and IKEEXT these need to be running for the VPN manager to connect to the key daemon.
/sbin/ifup: configuration for wlp18s0b1 not found.
Usage: ifup <configuration>
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.

The ifup command is the really old way of doing things and requires manual configuration. For wireless on CentOS 7 you almost certainly want to use NetworkManager directly either through GUI (Gnome/KDE settings or nm-applet and nm-connection-editor for lightweight WMs) or using nmcli.
The following example (as root) creates a connection configuration for your WiFi:
Centos 7 Broadcom Wireless Driver
But next time you don't want to create it again but you rather want to work with connection profiles:
Centos Wifi
Easy embroidery digitizing software. Once you are up and running on your WiFi network, you can learn more about the tools.
