the designers did not foresee there being other WiFi networks nearby that to which we want to connect. And since they have not planned this, taking tends to not connect to the closest and most powerful network, but randomly the first network overview, then HELLO PROBLEMS! designer have understood since they propose to go through a program they added later, "Management of AP" to connect to the proper wireless network. The connection for this management is anything but obvious !!! Most importantly, when we eventually find a way to change the AP restarts when the setting, it forgets the connection chosen !! normal, since the setting of restart disable erase everything and brings it back to the mode "factory", barring accidents, which unfortunately did not happen. So it is useless because it recovers again its AP chosen at random! So in short, very bad design practice, because he can kick off qu'n top of a mountain where there was only one WiFi network! Finally, I turned off all WiFi networks, I have asked my two neighbors énteindre their WiFi networks for an hour and ouff! I could then connect to my WiFi network propore! But not everyone has the opportunity to turn off the Wi-Fi networks in his neighborhood !!
