Slow Wi-Fi. Dropped connections. Staff walking to one particular corner of the office to get a signal. Sound familiar? Poor wireless is one of the most disruptive and widespread IT problems we see in Australian businesses — and it is almost always fixable.
Why business Wi-Fi fails
Most business Wi-Fi problems fall into one of four categories.
1. Consumer-grade equipment
Plenty of businesses start with a home router from JB Hi-Fi or Officeworks and never upgrade. Consumer routers are built for a handful of devices in a small house — not 30 staff with laptops, phones, tablets and other connected devices in a commercial building.
2. Too few access points
A single access point, no matter how powerful, cannot reliably serve a large open-plan office, multiple floors or a warehouse. Signal degrades with distance and struggles to get through walls, particularly ones with metal framing or concrete.
3. The wrong frequency band
Modern Wi-Fi runs on both 2.4 GHz and 5 GHz. The 2.4 GHz band carries further but is congested and slow. The 5 GHz band is faster but has shorter range. Without proper configuration, devices cling to a weak 2.4 GHz signal when a faster 5 GHz connection is sitting right there.
4. Interference
In commercial buildings, the neighbours' Wi-Fi networks, microwave ovens, Bluetooth devices and even old lighting can interfere on the 2.4 GHz band, dragging performance down for everyone nearby.
How to diagnose the problem
Free tools
Apps like WiFi Analyzer (Android) or Network Radar (Mac) let you see signal strength through the premises and spot channel congestion. A professional site survey goes further, mapping coverage and performance in detail.
Key things to check:
- Where does the signal drop below -70 dBm?
- How many other networks are on the same channel?
- Are devices connecting to the right access point, or roaming slowly between them?
The right solution
For most Australian businesses the answer is a properly designed enterprise wireless system. That means:
- Multiple access points positioned from a site survey — not guesswork
- A central controller managing every access point as one system
- Separate network names for staff and guests, with proper network isolation
- Band steering, to push capable devices onto the faster 5 GHz band
- Seamless roaming, so a phone stays connected as you move through the building
Systems like Ubiquiti UniFi or Cisco Meraki do all of this at a price point that suits small and medium businesses. A properly designed wireless network pays for itself quickly in recovered productivity.
