Hi Dispee, Thank you for providing the details, I appreciate it. I have checked the details and here is the direct link for the Wi-Fi driver. In case you do not get prompts on the screen for instructions, then Please reply if you have any questions.
Hi, I have problems with wifi. When I install windows 8 or Ubuntu wifi works fine, but with windows 7 even adapter not working. Windows 7 can't find update automatically and wifi driver from dell support site closes installation without finishing it.  I would stay with windows 8, but there is another problem. Radeon drivers not working same as wifi on windows 7..........  So any ideas ?  P.S. Sorry for my bad English.
