Bob has the Orbi Mesh Router and has a second router for work. Leo says you want one router to be in charge. Leo says your cable ISP wants to be in charge because they use their router to provide WiFi to anyone walking by. Then your work wants to be in charge because it can control everything. In general, you only want one router handling all the DNS address assigning. Leo recommends putting the Orbi in Bridge Mode, and that will prevent both routers from fighting to run the network (called "double natting").
