Hi,

It seems to me that on the Archer C64 the settings "WAN Connection Type: Normal" and "Get IPv6 Address: Auto" are the equivalent to the setting "Dynamic IP" on other routers.

"WAN Connection Type: Normal" and "Get IPv6 Address: Static" would be the equivalent to "Static IP" then.

  @woozle I tried the NORMAL and AUTO option but it didn't connect , and I wait more then 48 hour ! It's still not working ! 

  @RehoDesign 

Then there might be another problem somewhere.

Does your Archer C64 directly connect to the Internet via a modem or similar device or is there another router before the C64 that handles the Internet connection? 

  @woozle Yes, my Archer C64 is connected directly to the internet by ONU device. 
I don't know why it is not working but now I have to use the 6to4 Tunnel option ! 

  @RehoDesign 

If you hook up a computer directly to the ONU device via network cable (without using the C64) and connect to the Internet, does that computer properly retrieve IPv6 addresses? 

  @woozle No, My isp bind the link with the Onu and Router mac address, So I can't use the connection without this 2 devices.
