Newbie trying to establish wifi connection between ESP8266 and computer

Hi!

I've followed the setup instructions on using Arduino IDE and A Beginner's Guide to the ESP8266 - https://tttapa.github.io/ESP8266/Chap01%20-%20ESP8266.html

I got an ESP Access Point to show on my wifi network dropdown window. but on the next step, I could not get the mDNS to ping back.

In an attempt to find another way to setup wifi, I looked on the web and found this and installed it and uploaded to my ESP8266 - https://www.digikey.com/en/maker/blogs/2017/configure-your-esp8266-wifi-module-with-new-wifi-manager

And now I can neither see my ESP_0AA540 or the ESP Access Point in the wifi network dropdown.

What did I do wrong? How do I move forward?

Thank you everyone!

Solved!

Thank you!
