Thank you very much.
Now that we tried in many ways, I suspect that my PC hardware (Toshiba dynabook EX/33J, 2009) is too old to be supported by CentOS 7.

Did you install iw package also?
Yes, iw package is already installed.

Looking into your log again,

It seems to miss ifcfg-enp2s0 in the /etc/sysconfig/network-scripts. Has it been there right?

If not exist, you create it also as you did for wlp3s0.

I have deleted /etc/sysconfig/network-scripts/ifcfg-enp2s0 on March 12 as posted at that time.
Now I have recreated the file as shown below.

Hi

I found such a string in the /etc/sysconfig/network-scripts/network-functions

140 Wireless)
141 DEVICETYPE="eth"

I don't understand why it is mapped to "eth". I am not sure but, it would be "wireless".

Can you modify it and try again?

Thank you.
But it made no change.

# vi /etc/sysconfig/network-scripts/network-functions

# cat -n /etc/sysconfig/network-scripts/network-functions
.....
140 Wireless)
141 # DEVICETYPE="eth"
142 DEVICETYPE="wireless"
.....

# reboot

# nmcli d

Hi,

I am looking into NetworkManager.

I got a conclusion that if make_wireless_security_setting get an error, wireless connection would not created and then, NetworkManager create unhandled connection.
Mar 13 16:16:05 yokohama NetworkManager[895]: <warn> [1584083765.0901] ifcfg-rh: loading "/etc/sysconfig/network-scripts/ifcfg-wlp3s0" fails: Invalid WEP key length.
The above error is from make_wep_setting function which is called make_wireless_security_setting and make_wireless_security_setting is called by wireless_connection_from_ifcfg which make connection for wireless.

You can see this procedure as follows.
2 5974 /home/bchoi/work/NetworkManager/src/settings/plugins/ifcfg-rh/nms-ifcfg-rh-reader.c <<<unknown>>>
connection = wireless_connection_from_ifcfg (filename, main_ifcfg, error);
So, I think your WEP key would not correct. If you modify it correctly, you will get correct type as "wireless"

I checked the key again, but it is correct.

You need to find out what/who decides that your wlan device is an ethernet device. Candidates are kernel/driver, systemd, NetworkManager. I'd start with looking at the output of dmesg.

How about try again without WEP key?

"nmcli con add" command would not function with WEP key, "nmcli device" command handle WEP key.
