Router, Modem, Switch or Access Point?
ABC of network for small business
Setting up a network for small business can be confusing—especially with so many different devices like routers, switches, modems, and access points in the mix. At Turbo IT Solutions, we’ve seen many clients mix these up, which can lead to performance issues and connectivity headaches.
So, let’s break it all down in simple terms—without the tech jargon—so you understand what each component does and how they all fit together to build a strong, reliable business network.
Router: Your Network’s Post Office
In a network for small business, the router is your main device. It connects your internal office network (known as a LAN – Local Area Network) to the internet. Think of the router like a post office—it sends your data (emails, files, etc.) out to the world, and also receives information and delivers it back to your devices.
Modem: The Bridge to the Internet
Between your router and the internet is a modem. Its job is to translate the signal coming from your internet service provider (ISP) into something your router can use. Depending on your internet type, this could be a DSL modem (with an RJ11 jack) or a cable modem (using a coaxial connection).
Some ISPs, like Shaw or TELUS, provide all-in-one modem-router units. These combine both functions in a single box.
Turbo IT Tip: If performance from your all-in-one device isn’t great, we often recommend configuring it to function as a modem only, then using a higher-quality standalone router for better speed and reliability.
Switch: For Growing Networks
Most routers come with 4–5 Ethernet ports—perfect for a few computers and printers. But what if you’ve got 20+ devices to connect? That’s where a network switch comes in.
Think of a switch as a LAN extender. You plug it into your router, and then plug all your additional devices into the switch. Simple, effective, and scalable.
Access Point: For Wireless Connectivity
Prefer WiFi? So do most people. An access point (AP) bridges the gap between wired and wireless by turning your Ethernet connection into a WiFi signal.
Most modern wireless routers include a built-in access point, offering router + switch + AP functionality. But if you have a large office or lots of wireless devices, you might need to add extra access points to maintain strong coverage.
📶 Turbo IT Tip: Too many devices crowding one access point? Add more APs strategically throughout your office for stable and fast connections.
Can I Use a Spare Wireless Router to Extend My Network?
Great question—and the short answer is yes, but be careful. Reusing an old wireless router as a switch or access point can cause IP conflicts or network issues if it’s not configured correctly.
We’ve seen small businesses run into weeks of problems after adding a second router to extend a few LAN ports—only to call Turbo IT Solutions to untangle the mess. Don’t let that happen to you. If in doubt, consult with a professional before repurposing old hardware.
