Case study: Office Wi-Fi stabilisation for a small business

Improving a patchy office network with new access points and secure setup.

4 min read By PC Macgicians

A small business in Battersea SW11 was experiencing constant Wi-Fi dropouts during video calls and unreliable connectivity across two floors. We replaced the router, added access points, and configured secure staff and guest networks.

Case Summary

Device
Small business office network — router, access points, and connected devices
Problem
Wi-Fi dropouts during video calls and unreliable coverage across two floors
Diagnosis
Ageing consumer router with no access points to extend coverage to the upper floor
Fix
Site survey, router replacement, two access points added, and secure staff and guest networks configured
Outcome
Consistent Wi-Fi coverage across both floors, stable video calls, and a tidy managed network
Timeframe
Single visit

What Was Happening

A small business in Battersea SW11 contacted us because their office Wi-Fi had become a source of daily frustration. Video calls were dropping out mid-meeting, connections were unreliable in parts of the office, and the upper floor had noticeably worse coverage than the ground floor. The team had been working around the problem with mobile data hotspots on particularly important calls, but this was not a sustainable solution.

The existing setup was a single consumer router positioned near the entry point of the ground floor, which was too far from significant parts of the office to provide reliable signal.

Our Diagnosis

We completed a site survey of the office space, walking both floors with signal strength tools to identify the areas of poor coverage. The ground floor was adequately covered near the router but weakened towards the rear. The upper floor had consistently poor signal throughout.

The root cause was straightforward: one consumer router was insufficient for a two-floor office. The existing router also used a shared SSID for all devices, with no separation between staff devices and any visitors who might be given the password.

How We Fixed It

We replaced the consumer router with a business-grade unit and added two access points — one on each floor — positioned to provide overlapping coverage without channel interference. The access points were configured to use the same SSID for seamless roaming between floors, so devices automatically connected to whichever access point provided the strongest signal.

We configured separate staff and guest networks: the staff network has its own secure password and provides access to shared resources, while the guest network provides internet access only and is isolated from internal network traffic. Both networks were tested across the office before handover.

The Result

The Battersea office now has consistent Wi-Fi coverage across both floors. Video calls run stably and the team can work from any area without connectivity dropping. The guest network means visitors can connect easily without the business network password being shared.

Why This Is a Common Business Problem

Consumer routers are designed for residential use — typically one or two rooms at most. They do not have the transmit power, antenna design, or management features needed for multi-floor commercial use. Many small businesses start with a consumer router and never upgrade it as the office grows, until the connectivity problems become impossible to ignore. A properly designed small business network with appropriate access points is not significantly more expensive than a consumer setup, and the reliability improvement is substantial.

Prevention Tips

  • Conduct a site survey before purchasing hardware — the number and placement of access points depend on the building’s layout and materials
  • Separate staff and guest networks from the outset; it is easier to set up correctly from the beginning than to reconfigure later
  • Keep router and access point firmware updated; manufacturers release updates that improve stability and close security vulnerabilities
  • Replace consumer-grade networking equipment with business-grade hardware when an office grows beyond two or three rooms
  • If video calls are dropping out, check whether the issue is Wi-Fi signal strength before assuming the internet connection is at fault — these are two different problems with different fixes

Key Takeaways

  • A single consumer router is rarely adequate for a multi-floor office environment
  • A site survey identifies dead zones and the best access point placements before hardware is purchased
  • Separating staff and guest networks improves security and prevents guest devices consuming bandwidth
  • Video call stability is one of the first things to improve when signal strength and interference are addressed
