i'm running ubuntu 12.10 on a samsung 535u laptop.
i have installed ndiswrapper for connect my usb netgear wnda3100v2 to internet. but it is bugging and my internal wifi card and the usb i fighting to get the network and sometimes ubuntu is asking for network password, but is not connecting anyway, just still going on asking for password.. i get crash report all the time also. i think its a bad kernel mix.
