In Linux, wireless network card settings are typically stored in the /etc/sysconfig/network-scripts directory. Within this directory, you will find a separate configuration file for each network interface on the system. The configuration files are typically named ifcfg-<interface>, where <interface> is the name of the network interface (e.g., ifcfg-wlan0 for a wireless interface).
The ifcfg-<interface> files contain various settings for the network interface, including the device name, IP address, netmask, gateway, and other options. For a wireless interface, the file may also contain settings such as the wireless network's SSID (name) and security key (password).
It's important to note that the location and format of the network configuration files may vary depending on the specific Linux distribution that you are using. Some distributions may use different directory paths or file formats for storing network configuration information.
