Hi @SSJV 

Thanks for posting in our business forum.

Don't get any suggestions based on your description.

Have you changed the ONT recently? If yes, you might wanna reboot your ONT. This might be a MAC address issue.

But anyway, I would recommend you consult with your ISP about what should be done. Rebooting would be a very common step in fixing a new router/ONT. MAC clone basically equals rebooting because it flushes the existing MAC address on the router.

  @Clive_A Thanks for your reply.

From where I can check the ONT setting? 

I did the reboot for all the router, but it still not working.

Then you might contact the tech support of the ONT or your ISP to check this.

The router is only dialing the Internet and if we need to dig into this, I might need a result of the Wireshark, which seems not proper in your case. I don't think we should go into this so deeply and make you confused.

Just contact your ISP and ask about this.
