Hello LMichel,



Since the issue is only happening to some systems when they try to connected with your corporate network, we advise to perform the following:



- Delete the network profile, then recreate it accordingly.



If the issue persists, it may indicate a problem in the driver and a clean installation would be the best option. You can follow these steps to remove the driver components before installing the recommended version:



1. As first option try using the latest driver available from your http://www.intel.com/content/www/us/en/support/topics/OEMs.html Computer Manufacturer Support.


If the issue is not solved with the OEM driver, you can repeat the process using the generic driver version from https://downloadcenter.intel.com/ Intel® Download Center:



https://downloadcenter.intel.com/download/26346/Intel-PROSet-Wireless-Software-and-Drivers-for-Windows-10?product=86068 Intel® PROSet/Wireless Software and Drivers for Windows® 10 [19.20.0]



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. In Control Panel, Device Manager, Network Adapters, right click on the Intel® Dual Band Wireless-AC 8260 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 wireless driver is detected and installed, repeat the actions to uninstall and delete it as well. Repeat this process until the OS does not allow deleting the driver, or until the controller shows as Unknown Device.


5. Remove temporary files: Press the Windows Key + R to open the run box. Type Cleanmgr.exe. Press OK. Select the main drive, usually C:\. Check Temporary Files and uncheck everything else. Press OK.


6. Install the Intel Wireless driver. During the first steps of PROSet/Wireless installation, make sure to customize the installation and install all driver components.
