Wireless Nic configuration file

Wireless Network card configuration file-general Linux technology-Linux technology and application information, the following is a detailed description. Hello everyone! I am a newbie of Linux6. I just installed the system and everything is working properly. I can also access the Internet over wireless! (Click the link in graphic mode)
I want to change the wireless network to a static IP address and do not want to use dhcp, but I cannot see my wireless configuration file in the NIC configuration directory.
Cd/etc/sysconfig/network-scripts
Ls
Fcfg-eth0 ifdown-ipv6 ifup-plip ifup-wireless
Ifcfg-lo ifdown-isdn ifup-aliases ifup-plusb init. ipv6-global
Ifcfg-wlan0 ifdown-post ifup-bnep ifup-post net. hotplug
Ifdown-ppp ifup-eth ifup-ppp network-functions
Ifdown-bnep ifdown-routes ifup-ippp ifup-to-date-routes network-functions-ipv6
Ifdown-eth ifdown-sit ifup-ipv6 ifup-sit
Ifdown-ippp ifdown-tunnel ifup-isdn ifup-tunnel
The first three should be local wired NICs, loops, and wireless networks.
After that, I read the wlan0 file.
Vim ifcfg-wlan0.

DEVICE = "wlan0"
HWADDR = "00: 25: D3: F1: CA: 05"
NM_CONTROLLED = "yes"
ONBOOT = "yes"

I didn't see any network configuration information. Then I changed the wireless network to a static IP address in the graphic interface!

After reading wlan0, it's still the same
DEVICE = "wlan0"
HWADDR = "00: 25: D3: F1: CA: 05"
NM_CONTROLLED = "yes"
ONBOOT = "yes"


Where should I find my wireless Nic configuration file?
