Have you tried to clean uninstall from Device Manager and then, once you have uninstalled every thing you can go ahead and install it again.
Is this the card that came installed when you bought your computer? If so, we recommend that you install the drivers from you computer manufacturer.
Let us know if you need anything else regarding this issue.
Thank you for the response.
I had assumed that the later driver would install, even if an earlier driver had been previously installed. I've now done as you suggested, and a new driver has been successfully installed. Thank you.
However, the version that is being reported for the device is now 184.108.40.206, whereas the download page for the 64-bit Windows 7 drivers (https://downloadcenter.intel.com/download/24652/Intel-PROSet-Wireless-Software-and-Drivers-for-Windows-7-) shows file name Wireless_17.14.0_Ds64.exe - "Version: 17.14.0 (Latest)" (but file properties properties state Product Version 220.127.116.11).
Is this 18.104.22.168 the correct / latest driver, or is there a problem with the file?
Intel® PROSet/Wireless Software is a software package that contains the management software as well as the drivers for multiple Intel wireless adapters. In most cases, the driver version shown in device manager will not be the same as the version of the PROSet package you downloaded.
The driver version installed on your computer depends on the Intel wireless adapter and Operating system installed in your PC.
Currently, the driver 22.214.171.124 shown in device manager is the most recent driver available for the Intel® Centrino® Ultimate-N 6300 and Windows 7. This is the version that should be installed if you used Intel® PROSet/Wireless Software 17.14.0.
