Brian, I've used the Wi-Pi USB wifi adapter on a few different RPi models and it has worked well but I've only used it on Raspbian. https://www.element14.com/community/docs/DOC-69361/l/wifi-usb-dongle-for-raspberry-pi If you want to test one, let me know and I can lend you one. There is also the "official" wifi adapter from the Raspberry Pi Foundation: https://www.raspberrypi.org/products/raspberry-pi-usb-wifi-dongle/ Regards Graeme
