We visit a lot of small offices across Bexley, Sidcup, Dartford, and Erith. And in the vast majority of them, we find the same piece of hardware doing the same job it was never designed to do: a consumer broadband router — usually BT, Sky, or Virgin — running the entire business network. Sometimes there is a cheap Netgear or TP-Link box bolted on as an afterthought.
Nobody is to blame for this. When a business starts out, the broadband engineer drops in a router and it works. The IT guy never shows up to replace it. Years pass. Staff numbers double. Everyone just accepts that the Wi-Fi is a bit rubbish.
So what is actually different about a managed business network? Let us be specific.
What a consumer router is actually designed to do
Consumer routers — including the equipment your broadband provider supplies for free — are engineered for a single household. One family. A handful of devices. Light, intermittent usage throughout the day.
Their design priorities are: low cost, easy setup, and adequate performance for Netflix and web browsing. They are not designed for:
- Ten staff members on video calls simultaneously
- A mix of wired workstations, wireless laptops, mobile phones, EPOS terminals, and IP cameras
- Separating guest visitors from your internal file server
- Alerting you when a device drops off the network at 2am
- Rolling out a firmware patch remotely across your whole network
None of those things are on the consumer router's feature list. They are, however, on ours.
⚠️ The 15-user tipping point
Consumer routers typically handle concurrent connections adequately up to around 8–10 devices. Once you cross 15 active users — especially with video conferencing — you will see dropped connections, slow speeds, and erratic Wi-Fi that no amount of rebooting will fix. The router is not broken. It is simply operating outside its design envelope.
What a managed business network actually gives you
1. Proper wireless coverage, not one box of luck
A managed Wi-Fi deployment uses multiple access points, placed based on a proper site survey of your building. Coverage is uniform. There are no dead spots in the back office or the meeting room. When you walk from the front desk to the warehouse, your phone stays connected without dropping — access points hand off connections seamlessly using fast roaming protocols.
With a consumer router, you get one radio transmitter on one wall. Everything outside a 10-metre radius is luck.
2. Network segmentation — your most important security feature
A managed network divides your traffic into separate logical networks called VLANs. A typical installation we do has at least three:
- Staff network: Laptops, workstations, printers. Fully private.
- Guest Wi-Fi: Visitors get internet access, nothing else. They cannot see your internal systems.
- IoT / CCTV: Cameras, door entry, smart devices — isolated from everything else.
Why does this matter? If someone connects to your guest Wi-Fi with a malware-infected laptop, on a consumer router they are on the same network as your accounts system. On a managed network, they are entirely isolated. One compromised device cannot reach anything important.
Consumer routers do not support VLANs. Some allow a basic guest network, but it is a single checkbox, not a properly architected separation.
3. Real monitoring and alerting
When your network goes down at 11pm, do you find out now or at 9am when staff start calling? A managed network runs continuous monitoring. We get alerted when a switch port drops, when an access point goes offline, or when your broadband connection fails over to a backup link. Issues are often identified and resolved before anyone in your office notices them.
A consumer router has no monitoring capability. It either works or it does not, and you find out the hard way.
4. Centralised management and remote support
Every access point, every switch, every connected device on a managed UniFi network is visible from a single dashboard. When you call us with a problem, we can see your network in real time — which device is causing congestion, which port has a fault, which access point lost its uplink. We can often fix issues remotely in minutes without needing to visit your site.
With a consumer router, remote support means talking you through a web interface that looks like it was designed in 2009.
5. Quality of Service — prioritising what matters
QoS rules let a managed network prioritise specific types of traffic. Video calls get bandwidth priority over file downloads. Your VoIP phone system stays clear even when someone is pulling a large file from your server. Your EPOS terminals process transactions without competing with someone streaming a YouTube video.
Consumer routers treat all traffic identically. First come, first served. No exceptions.
Side-by-side: consumer vs managed
| Capability | Consumer / ISP Router | Managed Business Network |
|---|---|---|
| Multi-AP seamless roaming | No | Yes |
| VLAN segmentation | No (or very limited) | Yes — per-device isolation |
| Guest network isolation | Basic checkbox | Properly segmented VLAN |
| Traffic monitoring | None | Real-time per-device |
| Remote management | No | Full remote access |
| QoS / traffic priority | None | Configurable per application |
| Concurrent user capacity | ~8–10 devices comfortably | 50–200+ depending on hardware |
| Firmware management | Manual, often ignored | Remotely managed, scheduled |
| Proactive alerting | None | Automated monitoring |
What does a managed network actually cost?
This is where most conversations stall, so let us be direct about it.
A professionally installed managed network for a small office of up to 5 people — including a UniFi gateway, a managed PoE switch, an access point, and Cat6 structured cabling — starts from £750. A medium office of 5–15 people with additional cabling runs, multiple access points, and a UPS starts from £1,900. Larger offices or multi-floor premises will cost more — a free site survey confirms exact costs before any work begins.
That is a one-time installation cost. The hardware you own outright. There are no annual licensing fees on the platform we use.
If you want us to monitor, manage, and maintain the network on an ongoing basis — covering firmware updates, remote support, and proactive alerting — our managed services plans start from £30 per user per month. For a 10-person office, that is £300/month for a network that is proactively looked after by a certified engineer, rather than one that nobody checks until it breaks.
📈 The real cost of unreliable Wi-Fi
A business with 10 staff losing one hour of productivity per week to Wi-Fi issues — dropped calls, slow connections, rebooting the router — is losing roughly 520 person-hours per year. At even minimum wage, that is over £5,000 in lost productive time annually. A properly installed network pays for itself in the first year.
How do I know if my current network is the problem?
These are the most common signs we hear from business owners before we carry out a health check:
- "The Wi-Fi is fine in reception but terrible in the back office"
- "Video calls always drop at busy times"
- "We just reboot the router and it fixes itself for a bit"
- "It works fine when there are only a few people in"
- "We had to get a second router because the first one couldn't reach everywhere"
All of these are symptoms of a network that has outgrown its infrastructure. None of them are problems you have to live with.
Not sure what you actually have?
We offer a free, no-obligation network health check for businesses across Bexley, Dartford, Sidcup, Erith and the wider Southeast London area. We visit your premises, spend 30 minutes auditing your setup, and give you an honest written report. No sales pressure. No obligation to proceed.
