hi fellas here is my problem i cant enable wireless on my samsung q310 latop in windows i can enable it using Fn+F9 but some of the Fn shortcuts dont work properly in ubuntu and Fn+F9 seems to be one of them... i tried enabling it using the network icon on the panel but nothing happens when i click the enable wireless box i suppose the wireless driver doesnt work any more here is the output i get when i run iwconfig
