If you have received the message: "unknown error has occurred" or "network error", it is possible your ISP's "Advanced Security" is blocking the connection. Both Cox and Comcast/Xfinity have this feature on there respective WiFi devices. You have two options; a) allow access to the blocked sites, but for both Cox and Comcast/Xfinity, you can only do this for one (1) hour at a time, b) disable "Advanced Security" while accessing Foundations. Please see the ISP web pages for instructions to manage your "Advanced Security".
