Hey there dj003,
Welcome to the Apple Support Communities! You've come to a great place to sort the issues you're having connecting to your iPhone's Personal Hotspot. I know how handy that feature is, and I'll be glad to provide you with the resources you need to resolve this.
Take a look at this support article and the steps listed at the very top first:
Get help with Personal Hotspot in iOS
Since you're trying to access your hotspot using the Wi-Fi connection, if the above steps don't work, check out this section specifically:
On the device that needs to connect to Personal Hotspot, follow these steps. Try again after each step:
- Check that you're using the correct Wi-Fi network. The network name should be the same as the iOS device providing Personal Hotspot (You can check the name of your iOS device in Settings > General > About).
- If you see a password error when you try to join Personal Hotspot, check the Wi-Fi password: On the device that provides Personal Hotspot, go to Settings > Personal Hotspot to see the Wi-Fi password.
- Check how many devices are using Personal Hotspot by looking in the status bar of the device that provides Personal Hotspot. Some wireless carriers limit the number of connections you can have.
- On the device that needs to connect to Personal Hotspot, turn Wi-Fi off and back on.
You could also try one of the other connection methods to see if you get a different result.
Have a wonderful day!
