I have no doubt this worked for you. However, sitting in my car in front of the Apple store (an irony I cannot make up) and on the phone with Apple Support (since I was unable to get seen by the support staff at the store), my iPhone was (or had been) connected to my home Wi-Fi (which works fine).
As noted in my prior post, my iPad refused to cooperate with my "hotspot" on my iPhone. The iPad preferred the public Wi-Fi, which it could not connect to--again, a technological confusion I cannot explain. I had to drop the public Wi-Fi (all of this at the guidance of Apple Support, I add) to try to get to my iPhone as the preferred connection.
I wish that had worked. I really do.
Again at the prompting of Apple Support, after dropping the public Wi-Fi, I then had to drop the iPhone "hotspot" when the iPad found that as the preferred source (remember, my iPad would not allow me to enter the password even when it found my iPhone as a Wi-Fi source). I had to search for it as one of the network options in order to enter my password. Even then, there was no connection. I could not even link the two devices, another suggestion from Apple Support.
Now both Apple devices were unable to connect and there was no "hotspot". Exactly the worst of both worlds. Some support....
If this comes across as somewhat jumbled, I agree. Imagine being me, sitting in my car, in front of an Apple Store that offered no help, on the phone with Apple Support, which also offered no help, and with no Wi-Fi connection on either device. I'd add this is in a suburban location, not in some rural area lacking connectivity.
I am not a technologist, nor do I think I need to become one to operate my iPhone or iPad. This should be automatic or at most a one or two-click solution.
Apparently the iPhone "hotspot" works for someone somewhere. My friends use it and cannot figure out why it fails for me (offering suggestions similar to Apple Support, I may add, and just as useless).
I welcome being one of those people whose iPhone performs that function as well as my VERIZON hotspot works for my PC and Laptop. If my Apple devices worked as well, I'd be delighted. They seemed designed well, at least to the buyer's eye, but the technology, at least in my experience, underperforms consistently.
All hope is not lost and I am trying to keep the faith.
I will read the article you suggested. I have an appointment several days from now with one of the tech people at the Apple Store (there is a long line for help with Apple products, apparently--maybe Apple should take the hint they need better coders and designers). We'll see if they can fix it. In fact, I'll bring the article with me.
I will close with this. If they ask me to first connect my iPhone with the Apple store Wi-Fi, I will refuse. I will quote the article you presented, that I don't need a local Wi-Fi connection to use "hot spot" because, after all, if I need to connect one Apple device to a local Wi-Fi in order to use it as a "hot spot" so another Apple device can connect to the iPhone versus the local Wi-Fi, what is the point of using the iPhone as a "hot spot" for Wi-Fi?
Thank you for your thoughts here. I will keep you appraised of the outcome of all this.
In the interim, I will continue to use my Verizon "hotspot" and my PC and Laptop.
They connect. They work.
