Windows*10 provides its own inbox driver for the Intel® Centrino® Ultimate-N 6300. For the time being, Intel does not provide support for this adapter using this version of the OS. We recommend that you contact your computer manufacturer to see if they have any updates that might resolve this issue. On our best effort to help you, you may try the following:
1 - Download the Windows*8-compliant drivers: Intel® PROSet/Wireless Software and Drivers for Windows 8*
2 - Go to Control Panel, Programs and Features and Uninstall "Intel® PROSet/Wireless Software", if it is installed. When prompted, choose the option to "Discard settings".
3 - Reboot the PC or scan for hardware changes, check device manager and if an older driver is detected and installed, repeat the actions to uninstall and delete it as well.
4 - Repeat this process until the OS does not allow deleting the driver, or until the controller shows as Unknown Device.
5 - Once you have done this, proceed with the installation of the software from the link above.
Yes, Windows 10 has a built-in driver for the Intel Centrino Ultimate-N 6300. However, the driver seems to be having some significant problems on Windows 10. When will an Intel-supported update be released for this device? Installing a Windows 8 compatible driver doesn't sound like a good idea to me. Is this explicitly supported by Intel?

We would like to provide you a date but for the time being we have no information if there will ever be a driver update for Windows*10 on this adapter. The only available driver on our download center available is the one suggested above and yet there is no guarantee that it will work. We recommend that you use the inbox driver provided by the OS.

I also encountered reliability issues with inbox driver 126.96.36.199. Workaround which appears to be working is simply turning off high performance 802.11n mode within device manager. Driver is now connecting to access point at 54 Mbps which is sufficient for my use.
