I'm new on OpenWrt.
I try to create image file for my device U7621. I can get it once it works well but I added some interfaces on LUCI after, I want to edit config files and add these in image.
First like editing etc/config/wireless to create interface for wifi devices
config wifi-iface 'default_radio1' option device 'radio1' option network 'lan' option mode 'ap' option encryption 'psk-mixed' option ssid '...... option key '.....'
Also I want to add interface as shown default on LUCI, /like editing cat /etc/config/network
config interface 'UMTS option proto '3g' option ipv6 'auto' option service 'umts' option device '/dev/ttyUSB2'
I use the way SDK / make menuconfig for creation of image file.
To get these interfaces as default on LUCI,I could not find the correct files to edit these configuration in openwrt files. Could you show the path of these config files please?
