Newbie trying to establish wifi connection between ESP8266 and computer


I've followed the setup instructions on using Arduino IDE and A Beginner's Guide to the ESP8266 -

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 -

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!


Thank you!
