Can a NetGear N600 Modem/Router work w/ mesh?

Hi, I have a NetGear N600 cable modem router. The router part doesn't work that well, so I'm thinking of getting the Tenda Nova mesh wifi system. If I do that, will the mesh system over-ride what the router does OR will the devices conflict? If they conflict, should/could I put the modem (or router?) in bridge mode and if so how would I do that? Anything else I should know before I attempt to combine these two devices?
