What is broadband?
What's the difference between a modem and a router?
Most homes have a modem router which is essentially both units combined into one, but there are others who may have 2 separate units.
- A modem takes the internet data and translates it into a language our devices understand.
- The router then takes this translated data and distributes it to each device.
- If you've received a free modem router from your internet provider, chances are it's quite slow. The built in router is causing this. By buying a separate router, you're overriding the built in router with a better and faster one. Bye bye buffering boxsets.
What's a band router?
- You need a band router if your modem router is rubbish (as mentioned above) to improve your wifi performance.
- There’s 3 band router strengths, single, dual or tri band. Think of these as a single or dual carriageway, or motorway. The more lanes, the more traffic can travel.
- Then you can add extra units to optimise your home wifi. The below list will help you choose which set up suits you.
- Apartment/flat – standard set up with single band router is usually fine.
- 2 bedroom – standard set up, plus dual band router, plus wifi booster/s.
- 3 bedroom – standard set up, plus tri band router, plus twin pack mesh wifi system.
- More than 3 bedroom – standard set up, plus tri band router, plus triple pack mesh wifi system.
What is the difference between N and AC routers?
- As mentioned earlier, N is simply an older generation of wifi, and AC is a more current version, with higher speeds and is capable of more connected devices.
- AC routers range from AC600 to AC3000. The higher the number, the faster the connection. All N routers are compatible with routers AC750 and higher.
- Then there’s AX. A newly released version which sends info in bulk to your device, as opposed to lots of little bits of info making their own way. This means even quicker speeds, reducing the risk of buffering and long loading times. Result!
- If you're unsure whether you have an 'N' or an 'AC', just check the packaging or the back of the unit.

What is mesh wifi?
- Mesh wifi, or whole home wifi, is a way to spread your wifi throughout your entire house - from the bathroom, to the summerhouse.
- It identifies and targets each of your devices and the speed they can handle, then gives them what they need. This method optimises speed and strength of wifi as it’s specifically targeting each device.
- Whereas a modem router just chucks out wifi at a set speed which can be patchy in areas and is essentially a 'free-for-all' for your devices.
- Some brands enable you to implement parental controls so you can manage kids' screen time and what they view.
- And some offer a mesh wifi system with security features that will protect all devices when connected to your wifi.
How to set up a mesh wifi system
- It's so easy! Just plug your new whole home wifi system into your existing modem router, then use the provider's app to set it up. It’ll suggest turning off your modem router wifi for optimum performance. Et voila! An immediate wifi upgrade.
- Mesh wifi systems always come with at least a pair of 'hubs'. Dot the hubs around the house and as you move about, your device will automatically jump from one to another for a constant connection.
- You can add extra hubs if you have a larger home or just require further home coverage.

What is a wifi booster & range extender?
- Wifi boosters and range extenders are essentially the same thing. They pair up with your modem router and pick up its existing wifi connection to send and receive signals further.
- The initial set up requires you plugging it into a socket close to your modem router and syncing them to one another. Then you're free to move it to a socket further afield.
- It's worth noting that modem routers come with different speeds, they'll either have 'N' then a number, or 'AC' then a number. The higher the number, the faster is it.
- Wifi boosters and range extenders can only send out a signal that’s the strength of your modem router. So, if its strength is N300, it weakens as the wifi booster shares the power (N150 each) between the original router and the devices that’s connecting to it.
- Just to be super clear, a wifi booster – or range extender – doesn't make your wifi more powerful. Their actual purpose is to push the wifi further out (e.g. to the garden), so you have extra range.
Mesh wifi vs. wifi booster
Mesh wifi has one single network name. You join only once and remain connected. Whereas wifi boosters each have a unique name. So if you have multiple wifi boosters in your home, then you'll have multiple network names. E.g. 'mywifi_1, mywifi_2' etc. You have to connect your devices to each one before you can gain internet from them.
