I'm sorry for the issues you've been having. You said you've tried the current driver but have you tried deleting that driver, rebooting, and seeing if Win10 has a native driver that might work better? Or does it just end up installing the same driver version?
Also, have you checked the card itself to make sure it's physically seated correctly in the system, and that the antenna leads are tightly connected?
I'm curious, and trying to find out if there is a solution. I've asked a few contacts here internally and if i hear anything I'll let you know. In the meantime, to make it easier for me to provide information can you click on my Dell Todd username and send me a PM with the service tag of your system?
