rbr750 working, but now have two wifi networks of the same name, should I rename the old wifi?

I've just set up my rbr750 network.  Now I have two wifi networks with the same name.  Should I change the name of my original wifi network?  This would make it easier to tell the difference between the two wifi signals.  More importantly would my devices stay with the newer and hopefully stronger Orbi wifi signal?

Please post about this over inthe Orbi AX forum:

Turn OFF the old wifi router and just use the new Orbi system using the same SSID name and PW you have been using.
