Is your network switch the bottleneck?

What a switch actually does

If you've got more wired devices than your router has ports (or your router and PC are in different rooms with a switch somewhere in between), a switch extends your wired network. Most home setups don't need one at all — but if you've got one in the chain, it's worth ruling out as a cause.

Signs your switch might be the problem

What to buy instead

You don't need anything expensive or "gaming-branded" — a switch either forwards packets correctly or it doesn't; marketing tiers mostly add unnecessary features like managed VLANs you won't use at home.

Look for: - Gigabit (1000Mbps), not just "Fast Ethernet" (100Mbps) — this is the single most important spec - Unmanaged is fine and simpler for home use — you don't need the "managed" switches aimed at businesses - A reputable brand (TP-Link, Netgear, and similar all make perfectly good basic unmanaged gigabit switches) - Enough ports for what you actually need, plus one or two spare

A basic 5 or 8-port gigabit unmanaged switch is inexpensive and will comfortably outperform anything a decade old, regardless of price point.

Installing it

  1. Connect one port on the switch to a free port on your router (this is the "uplink").
  2. Connect your other wired devices to the remaining switch ports.
  3. No configuration needed — unmanaged switches work immediately, there's nothing to set up.
