      • Dear Sir,
        Incorrect unlock code will get displayed in the following cases:-
        1- Either you have not flashed the firmware or you have not restarted the router after firmware installation.
        2- The router is not accessible via web interface 192.168.8.1. Reset it to solve web interface issue.
        3- There is some other router connected to the network having the IP address 192.168.8.1. If yes, then remove the other router after login.
        4- Sometimes restarting the APP and router also solve the issue.
        We request you to write all the issues via email([email protected]) along with the supporting screenshots so that we can assist you in a better way.
