Hy, thank you for your answer.
I actually found a solution that is good for me and increases a lot the wifi speed.
I bought a wifi usb adaptor for 10€ on a local store and it solve my problem.
I boght a Dlink DWA-131, but i’am sure that for the same money or some more you could buy something better.
Like i said, my problem are solved.
Regards
