You might be suffering from what UK owners of Evolutions and SkyPortal external WiFi accessories have known for a long time. Celestron WiFi uses the 2.4Ghz channel, and in the densely urban populated South of the United kingdom, this channel has become so cluttered with interference it is almost unusable for telescope control. Smart houses where lazy folk cry "Alexa shut my curtains" or "Google turn on my central heating" are commonplace, all using the 2.4 Ghz channel. This clutter is now overwhelming.
If downloading a movie a few "lost packets" won't matter. But they will kill connectivity with a scope. The 2.4 Ghz channel is also prone to interference from nearby USB3 devices. I have a first generation Evolution and have tried second and third generation Celestron WiFi dongles. All failed. I now enjoy 100% reliable connectivity (using twin computers and RDP) over the 5Ghz channel that Celestron doesn't support. It is time Celestron upgraded to at least 802.11ac standard and offered dual-band options.
