I got a GoPiGo for Christmas with most of the extras including the wifi dongle. However, although the instructions made it seem like the WiFi dongle would work out of the box it didn’t. I was able to get it working and I’m posting the steps I took in case anyone else has the same problem.
The instructions I followed were found on this page:
The “Installing the rtl8188eu based wifi adaptor driver for Raspbian.” section.
To determine if your WiFi dongle is using the Realtek 18188EU chipset use ‘lsusb’.
If lsusb doesn’t tell you the chipset, run ‘update-usbids’ while connected to the internet and try it again.
