As you can see, even with the correct password, login is unsuccessful. Only by entering the correct password and adding a valid 6-digit dynamic password after the nickname can you successfully log in. Professional hacking service. 24/7 top-tier service.

Here we choose AX's Wi-Fi and begin capturing PMKID, a relatively new method from a few years ago used to crack WPA/WPA2 protocol passwords for wireless networks. Previous methods required attackers to capture the complete handshake packet when a user connects to the router. This new method, however, can obtain the PMKID by sending a request to the access point (AP) without a client, which can then be used for cracking. Furthermore, the researcher's article indicates that this attack works on all wireless networks that support and have roaming enabled, although it's unclear exactly how many routers it will be effective against.
