Hi,

From your post it sounds like you are not sure whether Dynamic IP or PPPoE should be used.

If that is the case, then I suggest you log into your old router, write down all settings that are related to the "Internet" connection and then configure the "Internet" settings of your Archer AX55 exactly like the old router is.

If you find something like a "VLAN ID" in your old router, then this will also have to be set on the AX55.

  @woozle I asked my provider some info about pppoe, still waiting.

I wanted to say that i found "type: VLAN 100 PPP WAN ETHERNET" and nothing more about vlan.

And i had static ip set that my provider sent me though email, but as i said getaway is starts with 81 and ip with 78 and tether app wont let me type those together.
