Comcast Business SecurityEdge and Wired Devices

I can not get my wired device, specifically Network Attached Storage (NAS), to work with my new Comcast Business network install.

I just recently had Comcast Business SecurityEdge installed. It has a modem (the modem is setup in Router Mode, this can not be changed) and two Arista OEM-AP-C75 access points (AP).

I have several Windows 10 computers, that are all connected on the Private wireless network configured on the access points. The computers can see and communicate with each other. I am just pointing this out to show that the wireless Private network is set up properly.

I have a NAS that I wold like to be available to the Windows computers. I first installed it on the modem (it has 8 network ports), but none of the wireless computers could see it. After a little investigation it appears that the AP's set up their own subnet. With this understanding I plugged the NAS into the LAN2 port of one of the AP's, but still none of the wireless computers can see it.

Is it possible to hook up wired devices that can be visible over the private network? The NAS I am trying to hook up (as with most [or all NAS's?]) is wired only.

Additionally is there a way to see what devices are connected to the AP's? In all of my past networks there was a configuration web page I could go to, usually under DHCP, where I could see all ofthe attached devices and their assigned IP addresses, but it appears with this cloud configuration set up no such detail configuration exists.

Thanks,

Dan
