Hi Chris,
I use the Skywatcher wifi dongle with SynScan pro on my android phone and SkySafari on my iPad to control my AZEQ6. Also have everything connected to a little wifi travel router, so not quite the same as you. However, the key thing I have found is that SkySafari needs to connect to the SynScan app not the wifi adapter. In your case, using SkySafari and SynScan on the same device (can’t do that with Apple devices) you need to tell SkySafari to use the address 127.0.0.1 and port 11882 (127.0.01 always resolves to the local device).
I think
this link covers it.
Can’t speak for CDC, Stellarium etc but you don’t need ASCOM for Android/Apple iPad with SynScan/SkySafari etc.
The other key point I have found is don’t let your SynScan device go to sleep, I use an app on mine to keep it awake. Once I have finished alignment the phone is out away and not used again.
