yesterday I installed Ubuntu 13.04 on my mother's netbook, Samsung NP-NC210 (http://www.samsung.com/in/support/model/NP-NC210-A01BD).
The problem is that it connects to my WLAN router only when I have disabled security. When I enable my WPA+WPA2 password, I cannot get the netbook connected.
I have tried changing the channel but the problem continues.
Any help would be very appreciated!
Thank you very much,
