My Goliath is connected with Slingshot but in the next step (sensors channel) when i choose configuration , nothing happens. There is no connection with the towers.
I had similar problem it is probably wifi issue try different options, once the connection established it should work well. Mine work with local net work but not all the time. Some one suggested a TP link dongle. Or use phone wifi.
The connection problem solved when I used existing network. You need to power cycle the robot to establish the wifi connection the log will look like this
