Most switches are compatible with cable modems and can be connected directly, provided they have the necessary Ethernet ports and support the same networking standards as the cable modem, such as Ethernet or Gigabit Ethernet. I understand that a Router is a device that can connect multiple networks between them, so I find no problem understanding how it can make the nodes from the local network to interact with Internet. But how does this works with a Hub and Switch, that are a bit more straightforward and simple. With a fiber ONT can I go straight into a switch? I have multi gig internet coming into my house via a fiber ONT. I am thinking of getting the deco x75 pro mesh routers that offers (1)- 2. 5gbps port and (2) gigabit ports. Unlike tudor -Reinstate Monica-, I'm on the FTTP (Fibre To The Premises) connection option, which effectively means that I have a completely fibre-based connection. Instead of upgrading my router, I'm considering placing an unmanaged 10gb switch between my modem and router (switches seem to be a LOT cheaper then routers) to allow other wired devices to take advantage of the full 10Gbps speed while still using my router for WiFi and DHCP. Do not connect your network switch directly to the modem because most modems do not have enough security to keep your.
