Why Your Office WiFi Is Slow (And It's Probably Not Your Broadband)

When a client tells us their office WiFi is slow, the first thing they usually blame is the broadband. Nine times out of ten, the line coming into the building is fine. The problem is what happens to that connection once it hits the airwaves.

It's usually the wireless design, not the line

Access points fitted years ago, placed wherever there happened to be a cable, fighting interference from neighbouring networks and the office microwave. That's the reality inside most buildings we survey.

Key Point

AP placement matters more than AP count. More access points in the wrong places makes WiFi worse, not better.

What a proper survey finds

  • Dead zones and weak coverage areas, mapped on a heat map
  • Co-channel interference between your own access points
  • Capacity problems in meeting rooms and dense seating areas
  • Rogue networks and external interference sources

We replaced 274 access points across 92 sites in four weeks — and the design work up front is what made that possible.

If your WiFi is frustrating your team, a survey will tell you exactly why — with the evidence to back it up. No guesswork, no "try turning it off and on again."
