WiFi Range Extender Question

[NavJitsU4]

I have an Asus RT-AC66R, I've set it up to send two WiFi signals (guest and private).

I need a range extender to reach the far corners of my office, my question is will a range extender extend both guest and private signals?

You'll have to read up on the manual. Some repeat all and others allow you to limit the SSID it repeats.
