I didn’t receive a support ticket either. I’ll post my email to you below:
Hi, I have had many problems on and off with my wifi connection. However I decided to go with the USB- it was working and then after some time, 20-30 minutes it was spiking to 5000ms and cutting out. When I would view the connection in Astro Pad and see this spiking, it would also flash the usb icon off and show the WiFi icon. This was really odd. I decided to turn off wifi on both my iMAc and my iPad but this would still happen.
What could cause this over a usb connection?
