If necessary, remove and the reinsert the Merlin EX720 into the Express Card
If the card still is not recognized, remove the Merlin EX720 and reboot the
computer. Once the computer is booted up, insert the Merlin EX720 again.

the installation process to complete.
The drivers and software should now be correctly installed. In Windows, you
can validate this by checking the Device Manager to make sure
there are no exclamation marks ("!") showing up. If this icon
appears, there is a problem with the driver.
Open the Sprint SmartView software and, on the Mobile Broadband
tab, click Connect to verify that you can connect.
The installation of Windows is not up-to-date.
Browse to Windows Update using an alternate Internet connection to ensure that all of the latest Service Packs and updates are installed.
Another application is conflicting with the Sprint SmartView software.
Ensure that applications such as ActiveSync, HotSync, WinFax and/or other connection managers are not running in the System Tray (i.e., the icons located by the clock on the Windows taskbar) while using the Sprint Connection Manager.
