I've just checked with our developers if they had heard from the problem and they have. Apparently, all it takes to solve this problem is to take the ROCKI and walk out of your wifi range with it. (Take it out of the house for exemple).
Make sure ROCKI is powered on while you do this. This will force ROCKI into hotspot mode. While still being out of range of your router, connect to the hotspot ROCKI created using your phone (or laptop). The hotspot will be called ROCKI_XXXXXX and the standard password is 87654321.
Once connected, open a browser and go to the ROCKI web config page:
http://192.168.0.1*Now walk back into range of your network.*
In ROCKIs web config page, fill in the SSID (network name) and password of your WI-FI network manually then click Save Settings. ROCKI will start up again, wait for 20 seconds and you should hear “Successfully connected to your wireless router”.
Give it a try and let me know if that helped!
