Well that is quite involved.  I did watch a youtube that talked about what looks to be the same.

I used to have that address to do the unlink but lost it.
I made a shortcut and placed it on my desktop so all I have to do is click the icon and
it disconnects my hotspot.   I have the 2 zero boards and will make up to shortcut icons for
each of the pi zero boards.

I'll have to think about if I want to get into making new channels with the leading numbers
so it knows which server to deal with using the gateway. 
I heard Prime is getting closer to taking over.
I would still have the problems trying to disconnect when tethering off my cell
phone unless that web address will work on the cell.  If it does I have to figure out
how I can get around having to type that out every time I need to disconnect

Thanks
