D-Link Corp. DWA-140 RangeBooster N Adapter(rev.B3) connecivity issue

I cannot connect using this wifi adaptor in Live opensuse 13.1 with KDE (it's the same on GNOME):

linux@linux:~> lsusb
Bus 002 Device 013: ID 2001:3c15 D-Link Corp. DWA-140 RangeBooster N Adapter(rev.B3) [Ralink RT5372]

linux@linux:~> uname -r
3.11.6-4-default

The device is correctly recognized and scans all the network but when I try to connect to a Network, it fails. The drivers are correclty installed:
linux:/home/linux # lsmod | grep rt
rt2800usb 22485 0
rt2800lib 74211 1 rt2800usb
rt2x00usb 20041 1 rt2800usb
rt2x00lib 53042 3 rt2800usb,rt2800lib,rt2x00usb
mac80211 548058 3 rt2800lib,rt2x00usb,rt2x00lib
cfg80211 444345 2 rt2x00lib,mac80211
crc_ccitt 12627 2 rt2800lib,ppp_async

I use this device also on opensuse
12.1 and there it works perfeclty.
