This is why I called AMPED support, because the instructions were a bit unclear. They don't recommend this. But, yes, you can use the same SSID; just overwrite the pre-filled info in the provided entry box. But, you may not want to. I've typically setup my add-on router with the same SSID/Password to allow roaming. (In theory . . ) Your Wi-Fi connected devices will jump to the stronger signal. But, you only know for sure if you run tedious tests or use a network analyzer. I never see the "jumping" happen unless I turn off Wi-Fi and then put it back on. And maybe not then, either . . and more testing. AMPED offers to clone your settings during setup, appending a few letters to the SSID to identify this new network. I let this happen (with a simpler ID), and used the same password. I now have to intentionally select this new network (but the password is saved for auto-connection). I no longer wonder if I'm using the better/nearer WiFi source. And, it really takes little effort to switch between networks.
