Imagine six people with megaphones
They’re standing close together, all trying to speak to different people in the same room. Everyone turns up the volume so they can be heard.
Would adding a seventh person with a megaphone make the conversations easier?
Probably not. The room already has plenty of sound. What it needs is a better arrangement: where people stand, how loudly they speak and when they talk.
Wi-Fi can have a similar problem. More equipment and stronger signals do not automatically give you a better connection.
Your phone needs to talk back, too
Now imagine you’re trying to answer someone with a megaphone using only your normal voice.
You can hear them clearly. That does not mean they can hear you just as well.
Your Wi-Fi equipment and your phone, laptop or smart device need to communicate in both directions. Turning up the equipment’s signal does not necessarily help your device answer it.
That is one reason you can see plenty of Wi-Fi bars and still have a frustrating connection. It is not the only possible cause, but it explains why signal strength alone does not tell us everything.
A real assessment with six Wi-Fi access points
During a recent visit, Jonathan found six access points—the devices that provide Wi-Fi—installed close together. They were transmitting at high power, using overlapping channels and taking up more radio space than suited the setting.
In megaphone terms, several speakers were standing near one another, talking loudly and getting in each other’s way.
The useful next step was to look at how the existing equipment was arranged and configured, before deciding whether more was needed.
This does not mean six access points is always too many. A large home, busy office or building with difficult walls may need that many or more. The number only makes sense in the context of the space.
Sometimes the answer is a quieter, better-organized room
A Wi-Fi specialist can look at the equivalent of:
- Where the speakers stand. Would moving a device put it closer to the people who need it?
- How loudly they speak. Is each device reaching the area it needs to, without unnecessarily crowding the others?
- How the conversations share the room. Can the equipment use the available radio space more effectively?
- How information gets into the room. Is the connection behind the Wi-Fi working properly?
The analogy has limits: Wi-Fi devices follow rules to share airtime, rather than simply shouting over each other. But they still have a shared resource to work with. Adding another device without a plan can add competition instead of solving the problem.
Should you buy another router or mesh point?
Maybe—but first, find out what is causing the trouble.
If a room has little or no coverage, another well-placed device may help. If the existing devices are poorly positioned or competing with each other, a change to the setup may be a better first step.
And sometimes the issue is elsewhere: the internet service, a cable or the device you’re trying to use. More Wi-Fi equipment would not resolve those problems.
You do not need to work out which explanation is right before contacting us. Tell us what you notice:
- “Video calls freeze in the back office.”
- “The bedroom has full bars, but nothing loads.”
- “We added another mesh point and it didn’t help.”
- “It works in one room and falls apart in the next.”
Those observations give us a place to start.
Get the equipment working together
Our job is to understand what is happening, explain it clearly and recommend a sensible next step. That might mean moving existing equipment, adjusting settings, fixing a connection or planning a different installation.
