Tp link 8817 modem setting

My ptcl zte 831 stop working. As i already have wireless router. So i bought just a modem rotuter

Can any one know the exact ptcl settings for it.

Adsl mode u can select only 1 at a time

Not like zte where i could select g.mat, adsl+ etc

Here i can select one like auto sync up or g.lite etc.

Should i select pppoe or dynamic io
