A WiFi router is the small box that takes the internet coming into your home and shares it, without wires, with your phone, laptop, smart TV and Explora. If you've just moved into a cottage in the Franschhoek village or taken over a guest farm, this plain guide explains what the box does, what the lights mean and how to get decent signal in every room.
Quick answer: A WiFi router turns one internet line (fibre, LTE or satellite) into a wireless network your devices can join. Put it high and central, keep it away from thick walls and metal, change the default password, and add a mesh router or cabled access point if one box can't reach the far end of the house.
What a WiFi router actually does all day
Think of the router as a traffic officer at a busy crossing. Data arrives from the outside world on one road. The router sends each piece to the right device and sends the replies back out.
It does three jobs at once. It hands every device a local address, it broadcasts the wireless signal, and it keeps strangers out with a password and a built-in firewall. Most models also have a few network ports at the back for devices you'd rather plug in with a cable, which our guide to decoder cables and connections explains.
What it doesn't do is create internet on its own. If the line from your provider is down, the router can still show a strong WiFi signal while nothing loads. That catches a lot of people out.
Modem, router or both? The boxes in your cupboard
Many homes have two boxes and don't know which is which. Here's the plain version.
| Box | What it does | Where you'll usually find it |
|---|---|---|
| Fibre box (ONT) | Turns the light signal in the fibre into a normal network connection | On the wall where the fibre enters, often near the front door |
| WiFi router | Shares that connection with all your devices, wired and wireless | Next to the fibre box, or in a study or lounge |
| LTE router | A router with a SIM slot that gets its internet from the cellphone network | Near a window facing the nearest tower |
| Satellite internet kit | A dish outside plus its own router indoors | Dish on a roof or pole, router in the house |
| Mesh unit | An extra node that works with the main router to cover more rooms | Halfway between the router and the dead zone |
Some providers supply a combined box that does both jobs. If you see only one box with a fibre cable going in and WiFi coming out, that's probably what you've got.
Reading the lights on your WiFi router
Every brand uses its own colours, so check the little picture guide that came in the box. Still, most follow a similar pattern.
- Power: solid means it's on. No light means check the plug and adapter.
- Internet or WAN: this is the one that matters. Red or orange usually means the line from outside isn't connected.
- WiFi or wireless: on or flickering means it's broadcasting.
- LAN ports: a light next to each port shows a cable is plugged in and live.
A red internet light is usually a provider or line fault, not a broken router. Restart the fibre box and router, wait two full minutes, and phone your provider if it stays red. After a power cut, our notes on restarting after load-shedding help too.
Where to put the router in a Franschhoek home
WiFi is radio, and radio hates thick walls. The older cottages around Bo-Dorp and the village have solid stone or double-brick walls that swallow signal. A router tucked in a cupboard at one end of the house will barely reach the other.
- Place it as central as the fibre point allows, at shoulder height or higher.
- Keep it out of cabinets, away from fish tanks, mirrors and the microwave.
- Stand the aerials upright if your model has them.
- Don't hide it behind the TV. Big screens and metal brackets block signal.
- Give it air. A hot router slows down and drops connections.
Farms and estates add distance. On a property near La Motte or Wemmershoek the cottage, the office and the main house can be 50 metres apart, and WiFi simply won't jump that gap. That's a job for a cable or an outdoor link, which we cover in our WiFi and network cabling work.
Technician tip: Walk the house with your phone and a free speed test app. Note where the speed drops sharply. Those spots tell you where the next access point belongs, far better than guessing.
The two WiFi bands in plain words
Most routers sold today broadcast on two bands, 2.4 GHz and 5 GHz. Some newer ones add a third. You'll often see two network names, one ending in "5G" or "5GHz".
- 2.4 GHz travels further and through walls better, but it's slower and more crowded.
- 5 GHz is much quicker over short distances, but drops off fast through brick.
- Newer bands on WiFi 6E and WiFi 7 routers are quicker still, but only help if your devices support them.
A simple rule: use 5 GHz for the smart TV and laptop in the same room as the router, and let far-off devices like a gate camera from a CCTV installation sit on 2.4 GHz. Many routers can merge both into one name and choose for you.

Router prices: what changes the cost
People in Simondium and Groendal often ask us why router prices range so widely, from a basic box at a supermarket to a premium unit at a computer shop. The short answer is that you pay for range, speed and how many devices it can juggle.
| What you pay for | Why it adds to the price | Who really needs it |
|---|---|---|
| Newer WiFi standard (WiFi 6 or 7) | Faster chips, better handling of many devices | Busy homes and guesthouses |
| Mesh support | Lets you add nodes later as one network | Long or multi-level houses |
| More and faster LAN ports | Better hardware inside | Homes with cabled TVs, decoders and offices |
| Guest network and parental controls | Extra software and updates | B&Bs and families |
| SIM slot or built-in LTE | Includes a cellular modem | Spots without fibre |
We don't quote wifi router prices as fixed numbers because shop specials change week to week. Compare on the day, check the box lists your connection type, and ask our team for a current quote if you'd like our home network installers to fit and set it up.
Good to know: The router your fibre or LTE provider gives you is often fine for a flat or small cottage. It's in bigger homes, with lots of guests or devices, that a better unit starts to pay off.
When one box isn't enough: mesh router or access points
A single router, however good, can only cover so much. When a home has dead zones, there are three common fixes.
A mesh router system uses two or three matching units that talk to each other and share one network name. You walk around and your phone hops between them. It's the simplest upgrade for a double-storey house or a long single-level home.
Cabled access points are the sturdier option. A network cable runs from the main router to each point, so every room gets full speed. Guesthouses with rooms across a courtyard do best this way, as we explain in our post on guesthouse WiFi and access points.
A range extender is the cheap fix. It repeats the signal but usually halves the speed. Our WiFi extender buying checklist covers when that's good enough.
Safety first: Outdoor access points and cable runs between buildings often go under eaves or along walls. Leave ladder and roof work to a technician, and never run network cable alongside mains power.
Set up a new WiFi router: first-day checklist
Whoever plugs it in, a few steps on day one keep the network safe and running well.
- Change the default admin password printed on the sticker.
- Give your WiFi a name that doesn't include your surname or address.
- Use a strong WiFi password with WPA2 or WPA3 security.
- Switch on a guest network if you host visitors or rent rooms.
- Let the router update its software, and leave automatic updates on.
- Plug the decoder or smart TV in with a cable where you can.
That last point matters for TV. A cabled connection is the steadiest way to keep streaming and Catch Up working, and our guide to connecting an Explora to the internet shows both the wired and wireless routes. If you're still choosing between a decoder and an app, read DStv Stream or a decoder first, because streaming leans heavily on your router.

WiFi router: FAQs
What is a WiFi router used for?
A WiFi router shares one internet connection with all the devices in your home, either wirelessly or through network cables. It also gives each device an address and keeps outsiders off your network with a password and firewall.
What is the difference between a WiFi router and a modem?
A modem or fibre box brings the internet into the house from your provider's line. The router takes that connection and spreads it to your phones, TVs and laptops. Some providers supply one box that does both jobs.
Can I move my WiFi router to another room?
Yes, as long as it can still reach the fibre box or phone line, either by moving that too or by running a network cable between them. Moving the router to a central spot is often the cheapest way to improve coverage.
Why is my router light red?
On most routers a red or orange internet light means the router isn't getting a connection from outside. Restart the fibre box and router, wait a couple of minutes, check the cables, and call your provider if it stays red.
Do I need a mesh router for a house in Franschhoek?
Not always. A flat or small village cottage often works fine with one well-placed router. Long farmhouses, double-storey homes and properties with thick stone walls or separate cottages usually need mesh nodes or cabled access points to cover every room.
