    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 "OTHER device F5521gw" which probably means that the hardware is installed properly.

    I have tried installing this Driver Details | Dell US 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 also have a problem similar to this. I installed a DW5550 into a M6700 and can not install the drivers. The card is shown in device manager as DW5550 under unknown devices. When I try the installer from Dell it says that authentication failed and no compatible device detected!!!

    I can help you overcome this problem. Can you find the driver_auth.exe file on your computer, copy it to the 5550 driver install directory and run the following command (in that directory) in a command prompt window and post the result?

    driver_auth.exe -M "dell_wwan_sysID.dat" D5550

    I have created a replacement file for the XPS 14, 15 and 17 series only and is attached, unzip & put this file in the driver install directory replacing the file and this should install the D5550 on the XPS. Let me know if this works if not run the command as above message and post here.
