Stuck into "Obtaining IP address" when connecting to WiFi I have a Nexus 4 with Android 4.4.3 on it.

I can't connect anymore to my home WiFi. I've done no update, and I was actually able to connect several weeks ago. I've done anything special.

Today I've tried to change my WiFi access name, reboot many times, turn on and off the WiFi, change the name of my phone but nothing works. I'm stuck at "Authenticating..." or "Obtaining IP address" when connecting to the WiFi.

I saw I'm not alone to have this problem on the Internet but I can't find a solution to my problem, so if anyone knows !
After new problems on other devices, I decided to reset my Livebox. There is no problem anymore ! My phone can connect to the WiFi :)
