AP, even the security is not matching.
=20
I check the code, and maybe caused by wpa_supplicant_select_bss in
events.c
=20
In the block about "try to find non-WPA AP", there is no check for WPA
ie liking in block "Try to find WPA-enabled AP".
=20
Check
  if (bss->wpa_ie_len =3D=3D 0 && bss->rsn_ie_len =3D=3D 0) {
   wpa_printf(MSG_DEBUG, "   skip - no WPA/RSN IE");
   continue;
  }

I think to fix, also need reverse check for WPA ie in the block "try to
find non-WPA AP", liking
=20
  e =3D wpa_blacklist_get(wpa_s, bss->bssid);
  if (e && e->count > 1) {
   wpa_printf(MSG_DEBUG, "   skip - blacklisted");
   continue;
  }
=20
+  if (bss->wpa_ie_len !=3D 0 || bss->rsn_ie_len !=3D 0) {
+   wpa_printf(MSG_DEBUG, "   skip - WPA/RSN IE");
+   continue;
+  }
=20
  for (ssid =3D group; ssid; ssid =3D ssid->pnext) {
=20
=20
Does anyone encounter same issue?
