A network switch adds wired Ethernet ports to your network when your router runs out. They’re inexpensive, plug-and-play, and indispensable for homes with multiple wired devices. This guide covers when you need a switch, what type to buy, and how to set it up.
What Is a Switch?
A network switch is a device that connects multiple devices to your network via Ethernet. Like a power strip but for network ports.
| Component | Function |
|---|---|
| Router | Connects to internet, manages local network |
| Switch | Adds Ethernet ports |
| Devices | Plug into router or switch |
Most home routers have 4 Ethernet ports. If you have more wired devices, you need a switch.
Types of Switches
Unmanaged Switch
- Plug-and-play
- No configuration
- Cheapest
- Good for most homes
Smart Switch
- Web interface for basic config
- VLANs (separate networks)
- QoS (traffic prioritization)
- Mid-range price
Managed Switch
- Full enterprise features
- VLANs, QoS, link aggregation
- Web/CLI configuration
- More expensive
- For business / advanced users
PoE Switch
- Powers devices via Ethernet
- Used for cameras, WiFi APs, VoIP phones
- Various port counts and PoE budgets
Common Port Counts
| Ports | Use |
|---|---|
| 4 | Apartment, basic expansion |
| 5 | Slight expansion |
| 8 | Most homes |
| 16 | Power user / small office |
| 24 | Office / professional |
| 48 | Large office |
For most homes, 5- or 8-port unmanaged switch suffices.
Speed Tiers
| Switch Speed | Compatible With |
|---|---|
| 100 Mbps (10/100) | Outdated, avoid |
| 1 Gbps (Gigabit) | Modern standard, recommended |
| 2.5 Gbps (Multi-Gig) | High-end home, future-proof |
| 10 Gbps | Power users, NAS, businesses |
For most homes, gigabit (1 Gbps) is right.
Top Network Switches for Home
| Switch | Type | Best For |
|---|---|---|
| TP-Link TL-SG105 | 5-port unmanaged | Basic expansion, $15 |
| TP-Link TL-SG108 | 8-port unmanaged | Most homes, $25 |
| Netgear GS308 | 8-port unmanaged | Quiet, fanless, $30 |
| TP-Link TL-SG1016 | 16-port unmanaged | Power users, $50 |
| TP-Link Omada SG2008P | 8-port PoE smart | Cameras + smart features, $130 |
| Ubiquiti UniFi Switch | Various | Pro-style home networks |
When You Need a Switch
| Scenario | Switch Needed? |
|---|---|
| 4 or fewer wired devices | No (router suffices) |
| 5+ wired devices | Yes |
| Wired streaming devices in entertainment center | Yes (4-port near TV) |
| Home office with multiple wired devices | Yes |
| Security cameras (PoE) | PoE switch |
| Mesh nodes wired | Yes |
| All-WiFi household | No |
Setting Up a Switch
| Step | What to Do |
|---|---|
| 1 | Plug switch power adapter |
| 2 | Run Ethernet cable from router to switch |
| 3 | Plug devices into switch ports |
| 4 | Verify devices get internet |
| 5 | Done — no configuration needed for unmanaged |
Unmanaged switches are truly plug-and-play.
Where to Place Switch
| Location | When |
|---|---|
| Near router | Centralized hub |
| Behind TV / entertainment center | TV, streaming devices, console |
| Home office | Computer, NAS, printer |
| Server / network closet | Professional setup |
You can have multiple switches at different locations.
Cascading Switches
You can connect switches together:
| Method | Use |
|---|---|
| Switch A → router; Switch B → Switch A | Extend coverage |
| Multiple switches per location | Lots of devices |
Unmanaged switches cascade automatically.
Smart vs Managed Switches
For most homes:
- Unmanaged is sufficient
- Smart if you want VLANs (separate IoT network) or QoS
- Managed rarely needed for home
For small business:
- Smart often appropriate
- Managed for advanced configuration
VLANs (Smart / Managed Only)
VLANs separate networks logically:
| VLAN | Purpose |
|---|---|
| Main | Trusted devices |
| IoT | Smart home devices |
| Guest | Visitors |
| Cameras | Security |
Useful for security but adds complexity.
PoE Switches
For cameras, WiFi APs, VoIP phones:
| PoE Standard | Power per Port |
|---|---|
| PoE (802.3af) | Up to 15.4W |
| PoE+ (802.3at) | Up to 30W |
| PoE++ (802.3bt) | Up to 60–90W |
Match PoE budget to total device needs.
Common Mistakes
- Buying 100 Mbps switch — gigabit-bottleneck
- Too few ports — needing another switch immediately
- Cheapest switch that has issues — pay slightly more for quality
- Buying managed when unmanaged suffices — overcomplicated
- Old Cat 5 cables with new gigabit switch — bottleneck
- Mixing speeds — slower devices don’t slow others on switch
Switch vs Hub vs Router
Often confused:
| Device | Function |
|---|---|
| Hub (obsolete) | Broadcasts everything to all ports |
| Switch | Sends data only to intended port |
| Router | Connects networks, often includes switch |
Hubs are obsolete. Switches are smart hubs.
Cost Comparison
| Type | Cost |
|---|---|
| 5-port unmanaged gigabit | $15–$25 |
| 8-port unmanaged gigabit | $25–$40 |
| 16-port unmanaged gigabit | $50–$80 |
| 8-port smart switch | $80–$150 |
| 8-port managed switch | $150–$400 |
| 8-port PoE switch | $100–$200 |
| 24-port managed | $200–$500 |
Switches are inexpensive for what they enable.

When Switch Doesn’t Help
| Issue | Why Switch Doesn’t Solve |
|---|---|
| Slow internet plan | Switch doesn’t speed up internet |
| Bad WiFi | Switch is for wired connections |
| Specific device problem | Switch doesn’t fix device |
| Old Cat 5 cables | Replace cables |
Switches add Ethernet ports — they don’t fix WiFi or internet.
FAQ — Network Switches
Q: Do I need a network switch? A: Only if you have more wired devices than your router has ports.
Q: Unmanaged or managed switch? A: Unmanaged for most homes. Smart/managed for VLANs, QoS, business needs.
Q: How many switch ports do I need? A: Count your wired devices, add 30% for growth. Most homes fit 5–8 ports.
Q: Will a switch slow my internet? A: No — gigabit switches handle full home internet speeds easily.
Q: Can I daisy-chain switches? A: Yes — connect them via Ethernet. Avoid cascading too many (latency adds).
