problem solved  I did a google serch I think and eventually found a link to dells website that gave me this file Network_Qualcomm_w7_x03_A01_WFi_BT_setup_ZPE  It worked perfectly so far The only problem was i unziped it  and then nothing . I had to go to the folder when it unziped the files and clicked on setup to get it to install. I have this file if any one needs it but im sure it can be found by serching for the exact file on this site. hope this helps some one else
