When to refresh your office network (and what good looks like now)

Almost nobody blames the network first. When video calls stutter and files crawl, people blame their laptop, then the internet plan, then the day. The network itself - the access points on the ceiling, the firewall in the comms cupboard, the switch nobody's looked at since the fit-out - is the last thing anyone suspects, partly because it's invisible when it works and partly because refreshing it feels like spending money on plumbing. But the network is exactly where a surprising amount of "everything's slow" actually lives.

The symptoms that point at the network, not the laptop

A few patterns tell you the problem is shared infrastructure rather than one person's machine. If the trouble follows the location instead of the device - the back meeting room is always bad, that corner of the office always drops - it's coverage, not hardware. If it gets worse as the office fills up, it's capacity: too many devices for the access points to handle. If calls drop when someone moves between rooms, it's roaming the consumer gear can't do well. And if a single heavy upload can choke everyone else, you've got no traffic management. When the complaint is plural - "everyone's slow" rather than "my machine's slow" - it's the network.

What good looks like now

A network worth keeping in 2026 has a few traits, none exotic. Business-grade access points with enough density and modern Wi-Fi (Wi-Fi 6, or 6E where the device mix justifies it) so capacity holds up when the office is full. A proper firewall rather than the all-in-one box the broadband provider shipped. Segmentation so guests, staff devices, and any internet-connected building kit live on separate networks and a compromise in one doesn't reach the others. And centralised management, so the whole estate is visible and updatable from one place instead of device by device. We design, deploy, and operate UniFi networks for this reason - it gives an SMB that managed, single-pane setup without an enterprise budget.

If you're weighing specific hardware, we've written up the head-to-head between UniFi and Cisco Meraki for small offices, which covers the licensing and reliability trade-offs we see in practice.

When to refresh, and when to limp on

You don't refresh on a calendar, you refresh on symptoms and risk. If the access points are past end-of-support, if the firewall no longer gets firmware updates, or if the network is flat with no segmentation, that's a refresh regardless of how it feels day to day - those are security and reliability gaps, not just speed ones. If it's only the occasional slow patch and the gear is still supported, targeted fixes (an extra access point for the dead corner, better traffic rules) can buy you a couple of years honestly. The line to watch is support status: once your network kit stops getting updates, the question stops being performance and becomes exposure.

Where to start

A short site survey usually tells you in an afternoon whether you've got a coverage problem, a capacity problem, or aging gear - and which of the three is worth spending on. That's the front end of our Network & Comms service, which covers the Wi-Fi, firewalls, and Teams voice as one managed estate, and it sits alongside the day-to-day Managed IT that keeps it healthy afterwards.

The network is the one bit of your office everyone depends on and nobody looks at. Diagnose the symptoms honestly, hold it to the modern baseline, and watch the support dates - do that and "the Wi-Fi's slow again" stops being a weekly event.
