Overview
Wireless that just works, everywhere
Patchy Wi-Fi, dead spots and a network everyone shares with guests are more than an annoyance, they cost time and create security risk.
WhizzIT designs wireless around your actual building and how you work: a proper site survey, business-grade access points, separate secure networks for staff and guests, and seamless roaming so devices stay connected as people move around.
Wireless is designed from a site survey of your actual building rather than a floor plan, then monitored once it is live so degradation is spotted before people complain. Across 2025 our average first response time was 9 minutes and our average resolution time was 6 hours, measured across every ticket we handled. We are a team of five engineers supporting more than 30 UK businesses, from two-user teams to organisations of 150+ users. WhizzIT is Cyber Essentials certified and a Microsoft Cloud Solution Provider, so our security fundamentals are independently assessed rather than simply claimed.

Why coverage maps mislead
Full signal bars and unusable Wi-Fi are compatible
A device showing four bars is reporting how loudly it can hear the access point, not whether it can hold a usable conversation with it. Most complaints about bad Wi-Fi come from environments with plenty of signal and too much interference, too many clients per radio, or access points shouting over each other.
-
Buildings defeat assumptions
Plasterboard is nearly transparent to Wi-Fi; concrete, foil-backed insulation, plant rooms, lift shafts and metal racking are not. Older buildings with thick walls and modern buildings with foil-lined insulation both cause problems, for opposite reasons. This is why a survey in the actual building beats a plan drawn from a floor plan.
-
More access points is a common way to make it worse
Adding units to fix a dead spot frequently degrades the whole floor, because neighbouring access points on overlapping channels interfere with each other. Correct channel planning and turning power down rather than up is usually what fixes a struggling network. Density needs designing, not increasing.
-
Guests, staff and devices should not share a network
A single shared network means a guest laptop sits alongside your file server and your card terminal. Separate networks for staff, guests and equipment such as printers, cameras and building systems keeps a compromised or simply infected visitor device away from everything that matters, and lets you apply different rules to each.
-
The shared password is the weak point
A pre-shared key known to every current and former member of staff cannot be revoked for one person, so in practice it never changes. Per-user authentication removes that problem entirely and means access ends when employment does, which is also the answer to the question an auditor will eventually ask.

What a survey produces
Design first, then install, then verify
A proper survey establishes what the building does to the signal, where the users and devices actually are, and what they are doing. The design that follows specifies access point positions, mounting, channel and power plan, and the cabling each position needs. Installing first and adjusting afterwards is how sites end up with equipment in the wrong places and no way to know why it is not working.
After installation the network is verified rather than assumed, walking the site to confirm real-world throughput and roaming behaviour. Wireless depends entirely on what is underneath it, so structured cabling and network monitoring are the two services most often specified alongside it.

Frequently asked questions

020 4634 2518Why not just use consumer Wi-Fi routers?
Consumer kit struggles with many devices, larger spaces and security. Business-grade wireless gives reliable coverage, proper segmentation and central management that consumer routers can’t.
Can you give guests Wi-Fi without risking our data?
Yes. We set up a separate, isolated guest network so visitors get internet access with no route to your internal systems or data.
Will Wi-Fi stay connected as staff move around?
Yes. We configure seamless roaming so devices hand over between access points automatically, with no drops during calls or moving between rooms.
Do you cover larger or multi-floor sites?
Yes. The site survey accounts for building layout, materials and floors so coverage and capacity are right throughout, including multi-floor and multi-site premises.
Technology partners
Brands we partner with
We hold partner status with the vendors behind the tools we deploy, so your licensing, support and escalation come direct from the source rather than through a reseller chain.
