+                By default, all networks will get same priority group (0). If some of the

+                which wpa_supplicant goes through the networks when selecting a BSS. The
+                priority groups will be iterated in decreasing priority (i.e., the larger the
+                priority value, the sooner the network is matched against the scan results).
+                Within each priority group, networks will be selected based on security
