Network Connection Services

Your cloud services are only as good as your office network. Microsoft 365, Teams calls, VoIP, cloud backups: all of it depends on a network and cabling infrastructure that works reliably. Most businesses set up their networks just to get things working, which is understandable when the priority is getting the team online. But a network designed only to "work" is not the same as one designed to handle cloud services well. The result is dropped Teams calls, slow file syncs, dead spots in the office, and staff switching to mobile data because the WiFi cannot keep up. If any of this sounds familiar, our guide to common network connection problems covers what to check first.

TechCloud handles office networking as part of our IT service. Not as a standalone cabling company, but as the team that understands what your network needs to support. We know how much bandwidth a 15-person office running Teams video calls actually requires. We know which access points handle that load and which ones fall over. We set up networks that make your cloud services work the way they should.

What Office Networking Actually Involves

For a small business with 5 to 50 staff, office networking means three things working together:

• Structured cabling comes first. Cat6 Ethernet cables run from a central patch panel to each desk, meeting room, and access point location. This is the backbone of your network and should be the primary connection for anyone sitting at a desk most of the day. Cabling does not fight interference the way WiFi does, which makes it faster and more reliable for cloud services that need consistent speed, such as Teams calls, OneDrive sync, and cloud backups. Properly terminated and labelled cables mean any port can be traced back to the patch panel without guesswork.
• WiFi is for mobility. Business-grade access points mounted on ceilings or walls provide wireless coverage for laptops, phones, and tablets when staff move between meeting rooms, common areas, or hot desks. Not the consumer router your ISP gave you, which was designed for a three-bedroom house. A typical 200m2 open-plan office needs around two to three access points to maintain consistent coverage, depending on layout and device count. WiFi supplements your cabled network. It should not replace it for staff who work from a fixed desk.
• Switching and patching. A managed switch connects everything: wired devices, access points, your fibre router. VLANs separate guest WiFi from your business network so visitors cannot access shared drives or printers. For more on how network segmentation protects your business, see our guide to firewalls and network security. A tidy patch panel inside a secured wall-mounted cabinet keeps all networking equipment out of the way and protected from accidental interference. Adds and moves take minutes, not hours of cable tracing.

None of this is complicated technology. But it needs to be planned around your office layout, your staff count, and the cloud services your business depends on. A cabling contractor can pull cables. They cannot tell you whether your network will handle 10 concurrent Teams video calls.

Why Your IT Provider Should Handle Your Network

Most small businesses get their office network set up by whoever installed the fibre line. The ISP technician runs a cable from the fibre box to a consumer-grade router, plugs it in, and leaves. This works for email and web browsing. It does not work when your business depends on cloud services.

The difference between a cabling contractor and an IT provider who handles networking:

• A cabling contractor installs cables and access points to a specification. They can run Cat6 to every desk and mount access points where you point. What they cannot do is tell you whether your network is ready for VoIP, whether your switch needs PoE for the access points, or how to segment guest WiFi from your business traffic.
• An IT provider who understands cloud knows what your network needs to support. TechCloud sets up networks knowing exactly what will run on them: Teams calls, OneDrive sync, SharePoint collaboration, VoIP handsets, cloud backups running overnight. This is why we pair networking with our Microsoft 365 setup. We configure Quality of Service so voice and video traffic gets priority over someone downloading a large file. We size the access points for the actual number of devices, not the number the box claims it can handle.

This is not about being a networking specialist. It is about understanding the full stack, from the cable in the wall to the Teams call on your screen, and making sure nothing in between causes problems.

What TechCloud Sets Up

TechCloud provides networking services for small businesses across South Africa. In Johannesburg and Gauteng, we handle installations onsite. For businesses elsewhere in the country, we project-manage the work remotely. We procure a local cabling company, brief them on the specification, oversee the installation via video calls and photo verification, and ensure everything meets the standard before sign-off.

What we handle:

• Office WiFi installation. Business-grade access points (Ubiquiti, Reyee, or equivalent) positioned for your office layout. We survey the space (onsite or via video walkthrough for remote projects), identify dead spots and interference sources, and install access points where they provide consistent coverage. Single SSID across all access points so devices roam seamlessly between them.
• Structured cabling. Cat6 cabling from a central patch panel to desks, meeting rooms, and access point locations. Properly terminated, tested, and labelled. We plan cable runs around your office layout to avoid power lines and other interference sources. For staff who sit at the same desk most of the day, a wired connection is always the better option for cloud services.
• Network cabinet setup. Wall-mounted or floor-standing cabinet positioned in a secured location away from general foot traffic. Patch panel, managed switch, fibre router, and UPS inside, all labelled and cable-managed. Keeping network equipment enclosed and out of the way prevents accidental disconnections and unauthorised access.
• Switch configuration. Managed switches with VLANs for network segmentation (business traffic, guest WiFi, VoIP). PoE switches where access points or IP phones need power over the network cable.
• VoIP readiness. If your business uses or plans to use a cloud PBX system, we configure the network for voice traffic: QoS policies, dedicated VLANs, and switch ports pre-configured for IP handsets.
• ISP coordination. We do not install fibre lines or provide internet connectivity, but we help you choose the right ISP and package for your needs, coordinate the installation, and configure your network equipment to work with the service. See our internet connectivity services for more detail on how we help with ISP selection.

Power Protection for Your Office Network

Whether during load shedding or an unexpected power outage, your network equipment needs to stay on. Even if your laptops run on battery, they cannot reach Teams, OneDrive, or your VoIP system if the network equipment has no power. A UPS (uninterruptible power supply) for your network cabinet is a standard part of any properly designed office setup.

What to protect and how TechCloud sizes the UPS:

• Fibre box and router. These draw very little power (typically under 30W combined). Even a small UPS keeps them running for several hours during an outage, meaning your internet stays up as long as your ISP's infrastructure has power.
• Network switch and access points. A PoE switch that powers two to three access points draws significantly more than the fibre box and router alone. TechCloud sizes the UPS to cover the combined load of all your network equipment, not just the router. The runtime depends on the total draw, which we calculate during the site survey or remote assessment.

With network equipment on UPS and laptops on battery, your team can continue working through a power outage using your fibre connection. If the ISP infrastructure goes down too, staff can switch to mobile data as a fallback, and because your files live in OneDrive and SharePoint, everything syncs automatically when the connection recovers.

Frequently Asked Questions

How much does office WiFi installation cost?

The cost depends on your office size, the number of access points needed, and whether cabling is already in place. A typical small office (10 to 15 desks, 2 access points, patch panel and switch) generally falls between R15,000 and R30,000 for equipment and installation. TechCloud provides a quote after an onsite survey or a remote video assessment of your office.

Should I cable desks or just use WiFi?

If your staff sit at the same desk for most of the day, cabling is always the better option. A wired connection does not compete with other devices for bandwidth, does not suffer from interference, and provides consistently faster speeds for cloud services like Teams and OneDrive. WiFi is ideal for mobility, such as moving between meeting rooms, working from a couch area, or connecting phones and tablets. The best setup combines both: cabled desks for daily work and WiFi for everything that moves.

Can you set up WiFi in a warehouse or workshop?

Yes. Warehouse and workshop environments need different access points (outdoor-rated or industrial units) and different mounting positions than a standard office. We assess the space for coverage, interference from metal structures, and the number of devices that will connect. The same principles apply: structured cabling to access point locations, business-grade hardware, and proper network segmentation.

What is the difference between a consumer router and business WiFi?

A consumer router is an all-in-one device designed for a home: router, switch, WiFi, and firewall in one box. It handles a small number of devices adequately. A business WiFi setup separates these functions: a dedicated router, a managed switch, and ceiling-mounted access points that each handle dozens of concurrent connections with features like band steering, seamless roaming, and centralised management. The difference becomes obvious when you have 20 staff on Teams calls simultaneously.

Do you install fibre lines?

No. Fibre installation is handled by the fibre network operator (Vumatel, Openserve, MetroFibre, etc.) and your chosen ISP. TechCloud helps you choose the right ISP and package for your business needs, coordinates the installation timeline, and configures your network equipment to work with the fibre service once it is active. See our internet connectivity page for detail.

Can you help if my business is outside Johannesburg?

Yes. For businesses outside Gauteng, TechCloud project-manages the networking installation remotely. We design the network specification, procure a local cabling company in your area, brief them on exactly what needs to be done, and oversee the work through video calls and photo verification at each stage. You get the same standard of work with TechCloud managing the quality, regardless of location.

How long does a network setup take?

For a typical office with 15 to 20 desks, cabling and WiFi installation takes two to three days. Configuration and testing adds another half-day. If your office already has cabling in place and you only need access points and switching, the work can be completed in a single day. Your team can continue working during installation with minimal disruption.
