Hi, While testing WPS we have encountered below scenario: AP: 2.4 and 5GHz radios have same SSID (WPS enabled on both) but different BSSID. First our DUT Connects to 2.4GHz Radio, does the WPS handshake and disconnects after EAP-Fail. After that when it attempts to connect again, based on the scan results it attempts connection to 5GHz Radio. This is because the wpa_supplicant is treating this connection as a fresh attempt and follows normal rules for choosing an AP. Shouldn't we make the SSID/BSSID with which we have completed the WPS handshake as a preferred network and try to connect to it first and only then attempt a fresh connection?
