Brand new AC1900 - No Internet

Just got a new Archer C80, but there's no connection. I have a Huawei HG8245H where I plugged Huawei [LAN] > TP-LINK [WAN]. I tried wizard configuration, PPPoE, Access-point. But nothing seems to work.
What could I be missing?
Have you tried dynamic IP configuration ?
If Huawei HG8245H is in router mode, this should work, but you'll have a double NAT in your network.
If you want to avoid that the approach is to use the Huawei HG8245H in Bridge mode and C80 as a main NAT device.
The indication of a double NAT would be the C80 WAN (Internet) port IP address. If it's private then that's the case.
Another way to avoid double NAT is to configure C80 in AP mode.
