Once again, my fritzbox 7490 is not working. On fritz.box it says “internet nicht verbunden”, even though the lights are ok (wlan and internet lights are green).

Last time i made a friend call the customer service in german and the only thing they did was reset something from there and everything was ok. It took literally 3 minutes. But they don’t understand me in english, i just need them to reset the damn thing from there!!!!!! Can someone help me please???
