Here's two no driver required devices for Windows 10.
$7.98 @ Amazon https://www.amazon.com/TP-LINK-TL-WN725N-Wireless-Adapter-150Mbps/dp/B008IFXQFU

PS. Both are units I carry in my PC Rescue Kit and were used today to test the no driver hunt statement I made here on Windows 10 Home and Pro versions.
The second unit is for those that want more range.
I have a Dell Inspiron Duo Laptop that originally came with Windows 7. I upgraded it to Windows 8.1 and finally Windows 10, which I've had been running for about, I don't know, a year? All of a sudden it quit connecting to the internet. A very tech-minded fried of mine told me that Windows 10 was not compatible with the Qualcomm Atheros WiFi Adapter that came with the computer. I gave it to him to see if he could find a new driver for the adapter and he said he could not. His only solution was to roll back Windows 10 to either Windows 8.1 or Windows 7. I've tried going to Settings, Update & Security, Recovery, Reset this PC, Get Started, but I don't see an option to roll back to a previous version of Windows. This is a PC that is used for mostly getting email and playing an occasional online game so nothing is lost if I have to reformat it. Right now it's a brick. By the way it only has two USB ports and no DVD drive. Any ideas? Thank you.
