Wifi Adapater issue with Fedora 17

view story

http://forums.fedoraforum.org – Hey, I am new to Fedora (I require it for some work) and installed it on my Dell XPS l502x. After installation my wifi adapter is not being detected at all. Could anyone tell me what needs to be done for this? I thought installing some firmware/driver might resolve the issue, but like I mentioned I am new to linux systems so don't know much. I tried find some information on some threads but none helped me. Thanks! (HowTos)
