Internet connection keeps dropping (Telus)?

Lately My internet connection keeps dropping, ill be in the middle of something then bam my connection is lost. The internet can stay on from 2 minutes - 6 hours, and is getting really annoying... I recently got a new modem, thinking it might be faulty I tried my old one that I know works and the connection is still lost. I called Telus but still had no luck the guy i spoke to thinks the modem is still faulty even though I explained that it wasn't the modem.. :/ Problem is I need the internet to get my work done... Not sure what the problem could be, pretty sure its not the modem.. Anyone have suggestions?
