Hi

I have a dell xps l502x running on windows 7 home premium. I recently bought a 5550 wwan card ( Ericsson F5521gw 2XGNJ) for which i tried installing dell wireless 5550 driver. it was not successful and i got the message saying authentication failed and no compatible device detected!

Windows device manager identifies the card as "unknown device F5521gw" which probably means that the hardware is installed properly.

I have tried installing this  http://dell.to/ZS24H1  driver multiple times and every single time i got a message saying

"Driver installation failed. No compatible Dell Wireless HSPA Mini-Card has been found on this computer. Please insert hardware and restart the driver installation.

I would appreciate it very much if you can provide a solution.

Thanks
