UniFi by Ubiquiti has become the de facto standard for small-to-medium enterprises (SMEs) in South Africa. It's affordable, scalable, and doesn't require a degree in network engineering to maintain. But it's not without its quirks—particularly in our Johannesburg climate and load shedding environment.
What Is UniFi and Why Does Johannesburg Choose It?
UniFi is Ubiquiti's software-defined networking platform. Unlike traditional enterprise gear from Cisco or Arista, UniFi bundles access points, switches, routers, and a central management console into one ecosystem. You buy the hardware (access points, typically), install the UniFi Controller software (on your own server or via their cloud service), and manage everything from a web dashboard.
For Johannesburg businesses, the appeal is straightforward: you get enterprise-grade features at SME pricing. A decent three-access-point deployment runs between R8,000 and R15,000—substantially less than traditional Cisco equivalents. Most importantly, UniFi works beautifully with load shedding. Many of our clients in Sandton, Rosebank, and the surrounding suburbs use UniFi precisely because the modular design means a power cut to one access point doesn't collapse the entire network.
We've assessed and deployed UniFi systems for everyone from architectural firms in Parkhurst to logistics companies in Kempton Park. The consistency is remarkable. But consistency doesn't mean "zero problems."
UniFi Setup: What Actually Happens in Our Workshop
When a client brings us a stack of UniFi hardware, the first step is always the same: site survey. We walk the premises, measure distances, identify interference sources (microwaves, cordless phones, neighbouring networks), and map out access point placement. This takes two to four hours depending on building size and construction.
Then comes the actual installation. We mount the access points, run Ethernet cabling back to the central switch, configure the UniFi Controller, and run performance tests. A basic three-access-point deployment in a Johannesburg office typically takes one full day. We charge from R599 for an initial assessment, then R4,500–R8,000 for the full installation depending on cabling requirements and complexity.
What surprises many clients is the importance of the controller. UniFi's web-based controller is where all your network intelligence lives. It tracks connected devices, bandwidth usage, security events, and guest access. Many people ask whether they can run this on their main office PC. We advise against it. A dedicated controller—either a small UniFi Dream Machine or a virtual instance on a backup server—pays dividends. If your PC crashes, your network doesn't follow suit.
Load shedding has forced us to rethink deployment strategies. We now routinely recommend UPS (uninterruptible power supply) units for the central switch and controller. A modest 1kVA UPS keeps your network alive through Stage 4 or 5 loadshedding events—critical for businesses that can't afford downtime during the afternoon blackout windows.
Common UniFi Problems We Solve
Over the years, we've developed a mental checklist of the most frequent UniFi issues. Most are software-related, not hardware failures.
Slow Guest Networks: Clients often complain that their guest WiFi crawls while the main network zips along. This is usually a bandwidth limitation you've accidentally set in the controller settings. We've fixed this hundreds of times—it takes minutes once you know where to look.
Intermittent Dropouts: A device connects, then disconnects every few minutes. This is typically caused by channel interference or power-saving settings on the client device itself, not the access point. We troubleshoot with a WiFi analyser app, adjust the UniFi channel settings, and often advise clients to disable power-saving on their laptops.
Controller Disconnection: Your access points lose contact with the controller. We've discovered this often stems from firewall rules on your main network blocking the controller's communication ports. A liquid damage assessment may be necessary if hardware is involved, but usually it's a software configuration issue.
Slow Speeds on Distant Access Points: The farthest office from your main switch reports poor throughput. This is bandwidth bottlenecking—your backhaul (the link between the access point and your central switch) can't keep up. We solve this by either running dedicated cabling or recommending mesh-capable access points that distribute load more intelligently.
Why Our Clients Choose ZA Support for UniFi
We're not a massive IT support firm. We're a hands-on workshop in Hyde Park where the technician who assesses your network is often the same person who installs it. That continuity matters. When your network hiccups at 2 p.m. on a Wednesday, you get someone who remembers your site layout, your device inventory, and your specific load shedding schedule.
We also understand Johannesburg's unique constraints. Water ingress from our summer storms, dust in industrial areas, and the electrical stress of load shedding transitions—these aren't theoretical problems for us. They're weekly troubleshooting cases.
For businesses requiring ongoing support, we offer warranty packages extending up to three years, covering replacement parts, emergency call-outs, and quarterly health checks. This is far cheaper than the downtime cost if your network fails during a critical client meeting.
Getting Your UniFi Assessment
Ready to evaluate UniFi for your Johannesburg business? Book online at zasupport.com/book for your R599 assessment, or WhatsApp us on 064 529 5863 to discuss your specific setup before booking. We'll walk you through site requirements, pricing, and timelines.
If you're already running UniFi and experiencing issues, we repair and optimise existing deployments too. Many of our clients initially installed their own systems, then brought us in when performance degraded. We'll diagnose the problem, often for less than you'd spend on a full rebuild.
For those keen to dive deeper into UniFi's technical side, Apple Support's networking resources offer useful context, though UniFi documentation itself is excellently written.
Frequently Asked Questions
Q: Do I need the paid UniFi Cloud Key controller, or can I run the software on my own server?
The controller is free software—you can run it on a Mac, Linux machine, or even a Raspberry Pi. Many of our clients do this. However, if that device fails, you lose network visibility and can't make configuration changes. We recommend a dedicated controller device (like the Dream Machine Mini) for businesses with more than five access points or those that can't afford controller downtime.
Q: How many access points do I need for my office?
A rough rule: one UniFi 6 access point covers approximately 100–150 square metres of open office space reliably. In Johannesburg offices with concrete walls, expect 60–80 metres per unit. We perform a site survey to give you an accurate number.
Q: Can UniFi handle guest networks securely?
Yes. UniFi's guest network feature isolates guest traffic entirely from your main network. Guests can't see your servers, printers, or company devices. It's one of UniFi's strongest security features and comes standard across all models.
Q: What's your warranty on a UniFi installation?
We offer one-year parts and labour as standard. Extended warranties up to three years are available, covering hardware replacement and twice-monthly health checks. Pricing depends on your deployment size.
Q: Does UniFi work during load shedding?
UniFi access points need power. During load shedding, they'll go offline unless backed by a UPS. We routinely install small UPS units (1–2kVA) for the switch and controller, ensuring your network survives Stage 4 and Stage 5 cuts. This typically adds R3,000–R5,000 to your deployment cost but is worth it for business continuity.
Q: Can you migrate us from an old Cisco or TP-Link system to UniFi?
Absolutely. We've migrated dozens of Johannesburg businesses. We'll run both networks in parallel during transition, so you experience zero downtime. Migration cost depends on your current setup but typically ranges from R2,000 to R6,000 for labour alone.
