It is said !
So, I have Arduino YUN and when it starts its WIFI network, I connect there.
At the moment, no problem except that the connection time is in extremely long .........
However, when I want to go in the interface of the YUN with the address http: // arduino.local, the browser (Google chrome) load during a good minute to mark in the end that the page is inaccessible...
I would thus want to know how to solve this problem and especially where from comes it ?
So, I have Arduino YUN and when it starts its WIFI network, I connect there.
After you connected did you change anything or is the Yun still as it was when you recieved it?
The first time you power up the Yun it will open a WiFi access point and the configuration page should be available at 192.168.240.1.
And is it possible that I have to make a special script for the arduino?
No.
The adress 192.168.240.1 don't work.
What is the IP of your hosts PC you are trying to connect from?
This can of course only work if your host PC is in the same 192.168.240.0/24 subnet as the Yun is by default. And of course that you did not change the configuration of the Yun.
The use of a URL (http://arduino.local) will only work if there is some kind of name resolution available and for that it s recommended to have the Apple Bonjour service installed. But using the default IP address with a Yun in default Access Point mode has to work or you have a more basic networking issue, likely with your host PC...
