What should I do to connect directly to my iPhone I tried a lot of things

On the iPhone, go to Settings>General>Reset>Reset Network Settings. That will clear all of your network and wi-fi settings. Power the iPhone off and back on again, then try to connect to your wi-fi.

Is your printer connected to your network? In other words, do you have internet coming into your home and is the printer connected to that? While a printer can create an ad hoc network, if the printer is not connected to the internet to start with, creating that wi-fi network is not going to help you with you iPhone, since it would not be an internet connection. While you may be able to see wi-fi on the printer, that may just be for connecting the printer to your network. It sounds as if your internet at home does not have wi-fi, is that correct?

Open Settings ➔ WiFI ➔ Choose your WiFi Network from the list of Networks that the iPhone will show you and then enter the password of that network and you should be logged in.

Can you unplug and plug back the power to your WiFi Router and retest?
