After updating to kernel 4.4 my old realtek will not work anymore, so I tried wirh a TP-Link Archer TU1 but without success... I would want to ask if exist a WiFi USB dongle that works out of the box with kernel >= 4.4?
I have used the Edimax EW-7811Un adapter with elementary OS. It is advertised as supporting Linux and is a popular choice for Raspberry Pi projects, which means it's nice and small, relatively inexpensive, and well-reviewed.
