Solution for this problem i very easy, start setup driver, go to temp folder, coppy manual drivers from temp folder, instal drivers manualy
 I tried to download this drivers, not working after all, it's says: "Autentication failed. The Dell Wireless HSPA Mobile Boradband Mini-Card cannot be installed on this computer. Plaease contact the Dell support for further information."  No solution for this problem :/
