Thank you for the post. I will forward your concern to the wireless support group for them to better assist.
I Am having the exact same issue with a Thinkpad 410S. Looking forward to a solution ... My laptop is essentially unusable without Wifi.
Having what I think is same issue on a Dell E4310 Latitude Windows 7 Pro . Started a day ago during windows updates
Updates to Proset wireless software and drivers failed 15.15.01
Intel Chipset Device software also failed 18.104.22.1682
Wireless modem does not even open . Working off hardwire connection
If this was caused by Windows Updates, you might want to disable Automatic Updates. Also, you might be able to undo the changes if your system had a previously saved restore point.
Another option is to do a clean installation of the wireless driver. Please follow these steps to remove any previously installed drivers before installing the recommended version.
1- Contact the PC manufacturer support to download and save their recommended version of Intel® PROSet/Wireless Software. As second option, you can download the generic driver from Intel® Download Center.
2- Go to Control Panel, Programs and Features and Uninstall "Intel® PROSet/Wireless Software", *If it is installed.
3- In Control Panel, Device Manager, Network Adapters, right click on the Intel® Centrino® Ultimate-N 6300 and Uninstall it, make sure you mark the option to "Delete the driver software for this device".
4- Reboot the PC or scan for hardware changes, check device manager and if an older driver was detected and installed, repeat the actions to uninstall and delete it as well.
5- Repeat steps 3 and 4 until the OS does not allow deleting the driver, or until the controller shows as Unknown Device.
6- Install the Intel® Wireless driver downloaded before. During the first steps of PROSet/Wireless installation, make sure to customize the installation and install all the 3 driver components.
That worked for me. I repeatedly uninstalled using the delete driver software option, rebooted, and then finally installed the latest using the Intel Driver Update Utility. Wireless access restored.
I've now got two "Microsoft Virtual WiFi Miniport Adapters" showing in the device manager, but I'm guessing that will not cause a problem.
