Cable buried, then problems

We had our cable buried yesterday, as soon as it was buried we started to have problems with random loss of internet.  Phone agents unable to connect to the router. Internet intermittent loss.   Comes and goes.  One time it was out we went outside and pushed the connector together and the internet started.  Since then random outage.  I don't know if it is a exterior cable connection problem or the XER10 router issue.
