Moved into home with existing set up - need help accessing network and devices

[Sjpville]

Would appreciate any help. We moved into a Lennar home with a ruckus switch and access points.I’m quite sure the WAPs are broadcasting networks.  I also have my own Wi-Fi network set up. From what I can see, there are at least one devices connected to the pre-existing WAPs. 

how do I gain access to the WAPs without resetting them? Assuming that if I reset the WAPs, those device(s) will no longer be connected to the WAPs and gaining access to those devices will be tougher.
