If it makes any difference, I'm trying to connect to a WPA2-personal encrypted wifi on a Dlink DIR-655 Draft-N router... The last kernel that I used that works was a 2.6.24.7 series kernel (I haven't yet tried to see if the 2.6.25.x kernel works) I thought of posting it here before trying to dig into it any deeper...
