WIFI network .

So we have this translator thing we used called Voyce it’s translates hospital language for patients that don’t speak English well but the problem is this service keeps disconnecting connects and disconnects . . I tried to look into the settings in the iPad but it looks like it’s locked down . So the doctors file a complaint about how our network is slow and that it’s on the IT side . . so what’s causing this issue ? is this the WiFi fault and how can we resolve this issue
