Hi I have have a XPS L502X. I decided to make a clean installation based on Windows 7 Ultimate.My problem is when I instal the driver for the 'Dell Wireless HSPA 5540' it fails with then warning: 'Authentication failed. The .... driver cannot be installed on this computer....' Do anyone have an idea how to install driver for this ? Thanks RegardsBQJ
