You have a wlp0s21f0u2 device there that looks like a wireless interface to me.

This notebook has internal RTL8821CE 802.11ac PCIe Wireless Network Adapter.
CentOS 7.6.1810 can not find it for there is no driver.

I would like to use TP-Link small USB wireless network adapter RTL8188EUS 802.11n in order to install the driver for working temporarily.

I also use external LED monitor at HDMI port, external keyboard and external mouse.

You have a wireless device listed and recognised by CentOS.

I've already installed elrepo-release-7.0-3.el7.elrepo.noarch.rpm
and kmod-8188eu-4.1.4_6773.20130222-5.el7_6.elrepo.x86_64.rpm

CentOS 7.6-1810 Desktop doesn't find this USB Wi-Fi adapter.

What might be the problem?

It DOES find it. It's listed there in your ip link show output.

I had a laptop with similar issues couple of months ago. Issue being that the built-in wireless device was recognized and a kernel module for it loaded, the network device was shown in the output of "ip link show", but the gui kept showing "no wifi adapter found" as in your posting from 2019/02/24 02:06:20.

The cause turned out to be in the handling of the key on the keyboard to enable/disable Wifi. For some reason an additional kernel module was loaded (incorrectly) that caused that the status of this key always showed up as "wifi disabled". Solution was to blacklist that module.

What is your output of:

Code: Select all

lsmod rfkill

Code: Select all

lsmod | grep wmi
