I am switching Internet providers and the one I am switching to only provides a modem. With my current provider they provide a modem/router to which I hard-wired a Linksys MX 4000 series mesh system (3 nodes). Do I need to get a router or can I connect the Linksys Mesh system to the modem? i.e. is the Mesh system also a router? If I need a router, do I have to stick with Linksys or can I get any router (looking at Asus RT AX88u)?
