It is assumed you configured the 'wifi-device' depending on your requirements and your hardware. The interesting part is the 'wifi-iface' stanza with its options:
- * 'device' points back to your radio (wifi-device) interface

- * 'network' points to the corresponding stanza in '/etc/config/network'
