  3. Hi, my device already unlock and i forgot admin user name and password, because already change by me previously.

    If i reset this device, it will be lock again or not? And user name and password will be back to default (admin ; admin)?

    Please help me. Thx.

    • Once the device is unlocked, reset will not lock it again. So without any worry you can reset it and the user name and password will change back to admin

    • Without LAN Port the process is complicated and requires to open and solder the USB cable on the board. So, we don’t recommend that process as it is risky. If you still want to do that way on your risk, kindly pay 6 USD. We will send you the detailed instructions.

    • No tested on b310s-925. If you want you can test it on your own risk. For testing purposes the code is free. If you want to test, send us an email with the complete system information of your router.
