I have a Dell E6420 with Windows 7 64-bit.
I have installed a wireless 5530 HSPA mobile minicard. Now I can't find drivers for it. I have downloaded R242754, R251154, R251276 and they all say: "Authentication failed. This card cannot be installed on this computer. Contact Dell Support".
Is it a 32/64 bit problem? R251276 is supposed to be for E6420 64-bit.
