Cisco Wireless issue w/ Network devices that aren't PCs.

I'm... not the most versed network admin... but i was handed the network and need to resolve it... and googleFu has left me high and dry.

Essentially i have an ASA handing out 60 vlans, to a switch stack of Cisco C3650s and a few 1702I access points.

On the network, PCS work great. Wifi and wired. However.. Wireless Printers, Sonos, Google Home, ChromeCast, any IoT device has issues. They don't see the cell phones on the network that control them or the ipads.

I can't seem to narrow down what could be the cause but its across all the vlans... (this is a residential managed wifi deployment... it was from the person previously in this position, going forward we;ve been using Ruckus/Brocade systems w/o issue in this type of envrionment, i'm just... cisco stupid)
