It’s obviously the user, who may or may not have an understanding of the problem and its solution.
Once again, no matter what I did, I couldn’t make my iPhone a hotspot.
I would turn on Cellular Data. The slider may or may not work. I thought maybe it was the extra hard screen cover I have. But other sliders don’t seem to have the same problem. If the slider for Cellular Data came on, then the Personal Hotspot slider may or may not come on. Sometimes it would; sometimes it would not. If it didn’t, then the Cellular Data slider would turn off.
If I gave up and asked my MacBook Air to join a network, it might or might not. I think, but can’t be sure, if I make mistakes twice in entering the password, then I can’t get on at all.
Now, comes the kicker. How many users know about General>Reset>Reset Network Settings? You have to be a user who visits the Apple “Community” or can think of keywords to find other sites with the appropriate answers.
But once you reset your problems are not over. If you ask to join the network on your other device, it won’t work. Why? Because the name you thought your iPhone had has now become iPhone. Either you use iPhone from now on, or you go to General>About>Name and change iPhone to the name you had given your phone.
“The Computer for The Rest of Us” from 1984 slogan has long disappeared. We are almost back to the nightmare of “1984” in that we don’t really have a clue what Big Brother Apple wants us to do.
