Internet just stopped working

Hello, i am piggybacking off my friends internet with a cloned modem and everything was working great from the start. 3 days ago while in the middle of downloading a few thing that were going well 1mps or more the internet just stopped working. it shows connected to a pc and 2 phones and the modem shows 4 green lights and 1 orange flashing indicating sending or receiving internet and the router shows blue aswell but i have no internet. idk what to do at this point. im manually reset both, checked cables and po6wwr chords, and even went to belkins site to factory reset it that way incase the was a bad update. i have also plugs directly in to both router to pc and modem to pc with the same result. any ideas???
