Replacement router for FTTC, will it autosetup?

[#1]

I have received the replacement router TG582n to put in place of the TG582n that keeps resetting and dropping wifi performance. Should this autosetup or will I need to do so manually, just want to know so I can find details before i unplug the old one if its manual.
Cheers

If it has been ordered properly, it should autoset up.
