arduino industrial 101 wifi problems

Hello

I'm having problems with connecting the arduino industrial 101 to wifi.
At first I tried to connect it the way it was described on the getting started page of the product.
This worked at my house but not on school.
My teacher helped me but he said we shouldn't connect via the web interface. He said we need to connect via the program running on the arduino. We tried to find a way to do this but we only found how to connect other arduino's with wifi shields to wifi via code here: Arduino - WiFi
We tried but this doesn't seem to work without a wifi shield.

If anyone knows anything about this or has experience connecting to wifi please let me know.
Also any documentation on the product is welcome since this is hard to find about this arduino.
