Hi, I am subscribed to DiGi home fiber and I recently bought a new TP-link Deco M4

I want to replace the existing Wifi router (ZTE ZXHN H198A) with the tp-link.

using default settings I was able to set up the wifi but I am not getting internet access.

I believe there is a communication issue between the Modem(ZTE ZXHN F600) and the tp-link using the default settings (dynamic IP and VLANs)

Can someone help me with this issue? Is there something that I need to change manually during the setup?

Thanks in advance
