Who I have the same questioned this topic

The iphone 7 shows up, but says it cannot connect. It is not even coming up with the box to enter password, just gives error when I try to connect. I used to connect my laptop to my iphone 5c hotspot all of the time without issue. I've tried to connect from other devices as well. Problem is with the new iphone 7.

I've followed all of the trouble shooting steps and also reset the network and restarted, software on phone up to date. HELP.
