I have a Raspberry Pi from this summer that is part of a Gopigo. I just received it now. I followed the instructions on your website and set up the wifi over the ethernet cable. The wifi was working and showing up when I clicked on Wifi Setup (in dex.local.)
Then I followed the instructions to update the software, which may have been for the Gopigo2. After updating, I no longer have wifi (adapter and network not showing up in Wifi Setup.
An error message had appeared during the update and a log.txt file appeared in the GUI. (See attachment below; I have included from where things seem to not be working.)
Might the drivers in my Wifi dongle, which were working before the update, have been affected during the update? I teach at a school and hope to start teaching 7th grade students how to work with the Pi and Gopigo.
