There are so many things that could be affecting this, it is hard to say for sure. In your case I would probably contact support and see if they have any insight into what is going on.
It seems you are not the only one having issues with Cam Pan Connectivity lately:
From what I have read, it might be helpful to trying “Flashing” the firmware back to a previous version (there are instructions in that thread for how to do this).
If that doesn’t help, I’m not necessarily saying your issues are being caused by one the things in the following post/list, but it might help give you some ideas of other things to consider:
I don’t claim that list is ACTUALLY comprehensive on connection problems, but it is a list of things I’ve found were making a big difference back when I was having regular connectivity issues and it was driving absolutely insane. So believe, I can relate to connectivity frustration. Hopefully the firmware flashing solution will work out for you.
Let us know if you figure out something to help with your situation.
