Ask HN:internet Woes

We're a smallish (under 20) people media production startup based In Toronto, and we've been getting really bad luck with our Internet. We've tried doing business with both of the monopolies in town) Bell for SSL, Rogers for coaxial), we've upgrade the router several times, but still the Internet keeps cutting off. We are ready to one to a different neighbourhood!

Is this common. Anybody overcome this without having to contract out a network engineer?
