Router vs Switch: What Each Device Does on Your Network
Routers and switches both have rows of Ethernet ports, so they are easy to confuse. They do different jobs: a router connects your home network to the internet, while a switch adds more wired connections inside your network.
Pros of a router
- Connects to the internet: links your network to the modem or provider equipment.
- Manages the network: assigns addresses, provides a firewall and usually creates Wi-Fi.
- Traffic control: features like parental controls and quality of service.
Cons of a router
- Limited ports: many routers have only three or four LAN ports.
- Placement constraints: usually sits near the modem, not always near your devices.
Pros of a switch
- More Ethernet ports: connect TVs, consoles, desktops and NAS drives with stable wired connections.
- Simple: unmanaged switches are plug and play.
- Affordable: basic gigabit switches are inexpensive.
Cons of a switch
- No internet routing: a switch cannot replace a router or create a network on its own.
- No Wi-Fi: switches handle wired connections only.
Managed vs unmanaged switches
Unmanaged switches work without configuration, ideal for homes. Managed switches support advanced features like VLANs and traffic monitoring, useful for home labs and small offices.
PoE switches
Power over Ethernet switches supply power through network cables to devices like security cameras and wireless access points, reducing the need for separate power adapters.
Speed considerations
Gigabit switches suit most homes. If your router or internet plan supports multi-gig speeds, consider a 2.5 Gbps switch for devices that can use it.
Typical setup
Connect the switch to a LAN port on your router, then plug wired devices into the switch. For a home office or entertainment center far from the router, run one cable to a switch there and connect several devices locally.
Switch vs more Wi-Fi
Wired connections through a switch give consoles, streaming boxes and desktops lower latency and steadier speeds than Wi-Fi, and they free up wireless capacity for phones and laptops. If a room already has one Ethernet outlet, a small switch is often the cheapest network upgrade you can make.
Verdict: which to choose
You need a router for internet access. Add a switch when you run out of Ethernet ports or want several wired devices in another room.
