How to install wireless-tools on CentOS 7 server?

Question

Computer networks

I want to deal with linux and at the same time with the server part. I installed CentOS 7, decided to connect USB WiFi, during installation the installer's graphical interface identified the adapter and connected to the wireless network, but after installation this adapter disappeared somewhere ... I started reading on the Internet (I even began to understand some little), I came across the iwconfig command and others like it, which should show wireless network interfaces, but woe, my server told me that such a command was not found, I started looking further, Google gave me that this command is present just in the wireless- package tools, well, I think it's ok, when I typed yum install wireless-tools, I got the following "No package with the name wireless-tools was found", Google didn't tell me anything about this ... In general, I'm at a dead end.
Please help me with this package.
