"Our Wi-Fi keeps dropping out" is one of the most common complaints we hear, and it's almost never actually the internet connection. The real causes tend to be a small set of predictable issues in the office network itself.
Cause 1: Too Many Devices on One Access Point
A single consumer-grade router or access point can technically connect dozens of devices, but performance degrades sharply well before that limit, especially with video calls and other bandwidth-heavy use running simultaneously. If dropouts get noticeably worse during busy periods or meetings, this is a strong candidate.
Cause 2: Coverage Gaps and Building Materials
Concrete walls, metal framing, and even some types of glass significantly weaken Wi-Fi signal. A single access point that covers the reception area fine can leave meeting rooms or the far end of an open-plan office with a weak, unreliable connection that keeps dropping as staff move around.
Cause 3: Channel Interference
In a busy commercial building with many businesses running their own Wi-Fi, overlapping channels between neighbouring networks cause interference that consumer equipment handles poorly. Business-grade access points can automatically manage channel selection to minimise this, which most consumer routers do not do well.
Cause 4: Outdated Firmware or Ageing Hardware
Access points running old firmware, or simply reaching the end of their realistic working life, become increasingly unreliable over time. If the hardware is more than five years old and hasn't been updated recently, this is worth checking before assuming the problem is something more complex.
Cause 5: Roaming Handoff Issues
With multiple access points, devices are supposed to hand off seamlessly as staff move around the office. Poorly configured or mismatched access points (especially a mix of different brands or models) can cause devices to hold onto a weakening signal too long instead of switching, which feels like a dropout even though coverage technically exists nearby.
How to Actually Diagnose It
- Note whether dropouts happen in specific locations, or everywhere - this points toward coverage versus a broader configuration issue
- Check whether dropouts correlate with busier periods - this points toward a capacity issue
- Check access point age, firmware version, and current device count per access point
- Consider a proper site survey if the cause isn't obvious - guesswork on access point placement is a common reason fixes don't stick
The Real Fix
In most cases, the fix isn't a single better router - it's a properly designed network with enough business-grade access points, positioned correctly for the building, and configured to manage channels and roaming properly. See our guide on business Wi-Fi design for how this should actually be planned.
Frequently Asked Questions
Is my internet plan the problem if Wi-Fi keeps dropping out?
Rarely - a dropped Wi-Fi connection and a dropped internet connection are usually different problems. Wi-Fi dropouts most often come from access point issues, interference, or too many devices on one access point, not the internet connection feeding the network.
Will simply buying a more expensive router fix constant dropouts?
Sometimes, but often not on its own - if the underlying issue is coverage gaps, interference from neighbouring networks, or too many devices per access point, a single better router in the same spot won't solve a coverage or capacity problem that needs multiple access points instead.
Why does Wi-Fi seem to get worse as more staff join meetings or video calls?
This is a strong sign of a capacity issue - a consumer-grade access point can technically connect many devices but degrades badly under real simultaneous load, particularly with bandwidth-heavy uses like video calls. Business-grade access points are built to handle this kind of concurrent load properly.
Could our office's building materials be causing the dropouts?
Yes, this is a common and often overlooked factor - concrete, metal framing, and even certain glass types can significantly weaken Wi-Fi signal between rooms. This usually means more access points are needed, positioned to work around the building's structure, rather than relying on signal alone to punch through.
We run proper Wi-Fi site assessments for Perth offices to find the actual cause of dropouts, not just guess and swap hardware.
