I cannot modify the ONT WAN configuration

Hello, friend!

There may be no option changes due to the permissions of the account you are logged in to.

You need to log in to the HG8447 as an administrator.

Because the HG8447 is a carrier product, and the forum also imposes restrictions on us, we cannot provide your administrator account and password. However, we explicitly instruct you to consult the ISP and they will tell you the administrator account and password of the HG8447.

At the same time, you can have them provide you with a solution for WAN configuration.

If you have any other questions, you are welcome to continue posting and asking questions. We will reply to you as soon as we see it.

the HG, EG, DG, MA, and EA products are access network products.
