How to Set Up a Network Switch
Set up an unmanaged or smart managed Ethernet switch: connect the router LAN uplink, read link speed LEDs, prevent switching loops with RSTP, and set VLANs.
Ethernet Switch Setup & Planning Guides
Expand your wired LAN ports reliably using unmanaged, smart managed (802.1Q VLAN), and 802.3af/at/bt PoE+ switches for workstations, access points, and cameras.
Adding an Ethernet switch is the single highest-ROI upgrade you can make for a home office or small business. Moving desktop PCs, NAS appliances, printers, Apple TVs, and WiFi access points off congested wireless airtime and onto dedicated full-duplex Gigabit or 2.5GBASE-T switch ports immediately eliminates packet loss and frees wireless bandwidth for laptops and phones.
Whether you are plugging in a 5-port fanless unmanaged desktop switch or designing an 802.1Q VLAN trunk with PoE+ power budgeting for ceiling access points and IP cameras, these guides walk through physical topology, uplink wiring, Spanning Tree (RSTP) loop protection, and link verification.
