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.
I am also having this issue. It worked with my husbands iPhone (ios15) but I will not work with my daughters older iPad. No issues before the update
Not helping , tried all , on iphone12 ios 15.1
Jack you are a genius! Works... thank you.
This worked great for 20 of our systems thank you @jack123654
Thank you, this was helpful and it worked!
I finally got it to work. Thanks for the info!
This works, thank you!!
I think in your case I would go and check on a USB wifi card which supports wpa3. or if if you ok to take it apart do reseaech on which card supports it and change the one you have inside.
