I mentioned it should be likely found by its mac-address, so you could attempt to connect to that or you can make the network temporarily visible. I have no idea if that works, what I do know is that we are not going to look at it, since keeping a stable wifi network connections for normal networks is already hard enough, and simply keeping issues open without someone looking in to it, is just a waste of time.
