|I had this problem with a novatel 3G stick. It turned out that the old drivers from a verizon card were loading for the novatel that was on a different carrier. Have you installed a different wireless broadband card in the past? |
Anyway, if you uninstall the driver for the card you have now, reboot, plug your card back into the computer and it installs without you having to install the drivers from the disc, then it is installing a previous driver.
You need to find that driver and delete it. With the card installed on your computer, you need to go to the device manager, right click on your card, go to properties, click on the driver tab, then click on driver details. This will give you a list of files you need to delete.
