I had something similar. They replaced all the cabling in my house but it didn't do a thing. Then the next tech came to my house and found one cable that wasn't replaced. He replaced that, and changed the connectors at the box down the street and the problem was fixed. We're not entirely sure which one of those fixed the problem.
A tech will likely come out with a new modem if you request a service call. He'll be able to tell right away if it is the modem. If the new modem acts the same way prepare for a baffled tech or two to come to your house to try to solve the problem.
