can't can't connect to the network wifi

[Gerard ROBIN <g.robin3@free.fr>]

Hello,
I tried to install 
debian-testing-amd64-CD-1.iso 2014-03-31 08:54  648M 
and 
debian-testing-amd64-xfce-CD-1.iso 2014-03-31 08:10  643M
but the step : network connection failed.

My ESSID is ok but when I give my key WPA the process failed.

However, With the wheezy installer the connection successful.

Thanks.
