My hot spot on my iPhone 12 won’t connect to my Surface since I upgraded to iOS 15.

The problem is that iOS15 only supports WPA3. The older Surface Pro 3 wifi driver does not allow for WPA3 connection.


You need to MANUALLY update the Surface Pro 3 wireless driver so it will allow WPA3 connection. The drivers will not pull in through the normal updates because Microsoft does not update drivers for Surface Pro 3's anymore. I found the driver for our SP3's here: Microsoft Update Catalog (the 2nd item down in the list).


If you are not sure if you can do this update - do not proceed! Call your local IT friend to help..

This will update the driver for the Marvell AVASTAR Wireless-AC Network Controller to version 15.68.17015.112

If you do not see the 'Marvell AVASTAR Wireless..' device, do not proceed with the following...


Download and extracted the drivers to a folder. Microsoft Update Catalog (the 2nd item down in the list)


Open device manager --> Network adaptors and right click on the Marvell AVASTAR Wireless-AC Network Controller

Click on 'Update Driver'




Then click on 'Browse my computer for drivers'




Then browse for the folder you created with the extracted downloaded driver files:




When it is done updating - reboot and you should be able to connect to your iPhone/iPad iOS15 Hotspot.
