Wifi Problem Liquid Jade S Lollipop

Seiton

Hello,

First, sorry for my very bad english (i'm french).

 

I have bought a Acer liquid Jade S and I updated the smartphone directly to lollipop 5.1. (I have not use the smartphone with android kitkat).

When the smartphone is update, I have reset to factory data. (I have read a advice when we update to lollipop).

 

My problem is : 

(With WIFI) Sometimes my smartphone don't load a internet page, and I don't have a error message, just a blank page. 

If I disconnect and reconnect the wifi, the page load without problem. (I say "the page", but I have the problem with all internet connection like facebook app).

I tried to :

- disable IPv6 on my router (it's a freebox v6)

- give a static ip

- change WPA2-PSK/AES to WPA2-PSK/TKIP

- change channel of wifi

- fill DNS of free (my internet access provider) inside the smartphone.

 

But nothing change. 

 

The problem is unpredictable, somestimes that work and somestimes i have this problem ...

 

Thank for your help

(Need a teacher in english !!! )
