gl-b1300 wlan to fritzbox

Hello! I am new here and because I would like to move soon I would like to know whether I can only connect my gl-b1300 in my new apartment with wifi with the existing Fritzbox. I have set up the gl-b1300 as a vpn router for the whole family and would like to place it away from the Fritzbox.

Do you mean connecting B1300 to your current wifi network as repeater?

If yes then it should be simple.
