Time taking to download ESP8266.

I am trying to download the NodeMCU Board by following all the exact steps on the internet but it takes a lot of time (Approx. 10-12hrs) and in between the downloading process it shows a error and the download starts again which again takes a lot of time. I put this link into the additional boards manager : http://arduino.esp8266.com/stable/package_esp8266com_index.json

And after this I go to Tools>Board>Board Manager and download the esp8266 by the esp8266 community and it takes a lot of time.

What should I do? Please help.


When I was installing all this a few of years ago, I was having some trouble, too (but not the "10 hours" part). I couldn't find anything about it at the time and I was going to give up till I looked under the hood a little more.
Under the Network tab, in Preferences, I clicked (without a clue) the Auto-detect proxy settings button and then it worked out.

Wait a minute...
I went back a found the posts that I made about it all
back then (different windows, different laptop)
I had to click "No Proxy"
