According to Cisco Meraki's technical documentation, a maker of business networking gear, a Wi-Fi access point running in repeater mode loses half its throughput at every hop back to the main router — the second repeater in the chain already delivers only a quarter of the original speed, and the third, an eighth. That happens to be the most common way small companies "fix" their Wi-Fi: buy the same router used at home and keep adding repeaters down the hallway, across the room, into the warehouse.

The result is familiar to anyone who works in a small or mid-size company: the Wi-Fi drops out at the back of the warehouse, the video call freezes right as someone starts presenting, and the handheld scanner in the stockroom loses its connection in exactly the aisle where most of the inventory sits. Nobody can say for sure whether the culprit is the internet plan, the router, or the laptop — and every guess turns into a phone call, a swapped device, or one more complaint.

For whoever approves the IT budget, the right question isn't "which router should we buy." It's whether the company's wireless network was actually designed — with the right number of access points in the right places — or whether it just grew by patchwork, one repeater after another, room after room.

Why a Home Router Doesn't Scale

A home router is built for a house: a handful of rooms, a small number of devices, people using Wi-Fi at different times of day. In a company, dozens of people use the network at once, on the same floor, often in the same meeting room — and the equipment that can handle that is a different category altogether.

Cisco Meraki itself, when guiding customers on how many devices an access point can hold, is direct about it: the numbers it publishes — from a couple hundred devices on an older access point to close to a thousand on a recent model — are a theoretical ceiling. In practice, the interference created by everyone using the network at the same time pushes that number down well before it gets there.

That interference grows when neighboring access points share the same radio channel — two nearby floors, two adjoining rooms, each competing for the same airtime. It works like two people talking over each other in the same room: the more devices fighting for the same channel, the slower the conversation moves for everyone.

The cost doesn't show up as a single line item. It shows up as an employee's hour lost waiting for a page to load, as the same support ticket filed again, as a meeting rescheduled because the video call dropped halfway through.

Why Adding More Repeaters Doesn't Fix It

The common way to grow the network is to buy one more router just like the one at home and set it up as a repeater, picking up the signal from the previous one instead of running its own cable. It works for a while — until the company opens one more room, hires a few more people, or the warehouse grows another aisle.

That's when the hop problem shows up again: each repeater in the chain cuts speed in half relative to the one before it. On a far end of the building with two or three repeaters stacked in a row, the signal still reaches, but too slowly for a video call or for the system running the warehouse floor.

There's a second, less visible problem: the laptop doesn't switch access points on its own when the signal weakens. It tends to "stick" to the farthest one until the connection drops entirely, instead of quietly moving to the closer one as the person walks through the building — because home equipment was never built to hand off connections smoothly while someone is on the move.

And then there's the visitor. Without a network of its own for outside guests, the vendor who asks for the Wi-Fi password joins the same network as the company's computers, competing for bandwidth with finance and seeing the same devices any employee would see.

What Has to Be in Place

An environment built for this relies on verifiable mechanisms, not on buying one more router whenever the last one seems weak.

A coverage plan before any purchase. Someone measures signal strength across the office or the warehouse — including wherever the inventory scanner travels — and defines how many access points are needed and where, instead of buying equipment and testing it in the dark.

Access points wired in, not chained as repeaters. Each access point connects straight to the company's network over its own cable, without depending on a neighbor's signal. That's what avoids the speed loss at every hop.

Radio channels planned across rooms and floors. Nearby access points use different channels, so they aren't competing for the same airtime.

Smooth handoff between access points. The laptop or the handheld scanner switches access points on its own as someone moves through the building, without dropping the connection or freezing the screen for a few seconds.

A separate network for visitors. Anyone coming from outside connects to a network of its own, without competing for bandwidth or seeing the company's internal devices.

Someone watching before the complaint comes in. A dashboard shows how many devices are connected and where the signal is weak, instead of waiting for an employee to call it in.

This is how Skills IT works: with a coverage plan before installation, wired access points instead of chained repeaters, and a separate network for anyone visiting the company.

The Payoff for Whoever Decides

The payoff shows up first in the daily routine: the video call doesn't freeze mid-presentation, the warehouse scanner keeps its connection in the farthest aisle, and employees stop wasting time guessing whether the problem is their device, the router, or the internet.

Newer equipment helps, but it doesn't replace the design work. Recent standards like Wi-Fi 6E and Wi-Fi 7 promise more simultaneous capacity, partly by using the 6 GHz band — except in Brazil, that band sits in the middle of a regulatory dispute: in December 2024, Anatel reversed its 2020 decision that had opened the whole band for Wi-Fi, and restricted it to a single channel, setting the rest aside for a future carrier auction. Buying the newest equipment without a coverage plan solves less than it appears to.

The financial payoff is the usual one in well-run IT: less staff time lost, fewer repeat tickets for the same dead spot in the building, and a network budget that gets decided once, with an estimate before the purchase, instead of turning into an emergency buy every time a new complaint comes in.

There's also a payoff at decision time: with a coverage map in hand, it's possible to tell whether the problem is the internet plan, the cabling, or the placement of one access point — instead of swapping parts one at a time until something works.

A Starting Checklist

Before buying one more router or one more repeater, these are worth bringing to the next meeting:

  1. Is there a map of where the signal is weak, including the warehouse, storage areas, and outdoor spaces? Without that map, every complaint turns into a fresh guess about which piece of equipment to replace.
  2. How many access points exist today, and is any of them acting as a repeater for another? Every hop in the chain is speed already cut in half before it reaches the user.
  3. Is there a separate network for visitors and vendors? If the answer is "everyone uses the same password," there isn't.
  4. What happens when someone walks from one room to another with a laptop or scanner in hand? If the connection drops or freezes for a few seconds, the access points aren't delivering the smooth handoff they should.
  5. Who decides how many access points the company needs: an actual measurement, or that month's budget? The right answer is the first one.
