Can't understand Sparkfun ESP8266 tutorial

I try this experiment with the link below. I cannot understand due to my stupidity.

https://learn.sparkfun.com/tutorials/esp8266-thing-development-board-hookup-guide/example-sketch-web-server

I manage to upload without error. But when I try to access the webpage with thing.local/read, i get error loading webpage. As it mention, the links will only work if your device is on the same network. But i couldnt find my wifi in my notebook and also couldnt find any wifi with my mobile phone.

So, kindly help me to understand how to make this work.
