This issue is more on the computer rather than on the router. The computer can identify a network/router/device uniquely and assign a profile name to that device. And when it detected your new router it automatically added a  profile name to it with a numeric value of 2 since it detected it as a router but not the same one as before even though you have the same wifi name on it. There's an easy fix on for it, just follow the steps on the site below, I recommend to follow the 2nd set of instructions using Local Security Policy or "secpol.msc".

I hope this helps.
