This guide draws on our workshop experience fixing network equipment alongside Apple devices. We've helped more than 18,000 customers across Sandton and Hyde Park resolve connectivity issues, and we've seen the same patterns repeat. Let's walk through what actually works.
Why UniFi Systems Fail in Johannesburg
Sandton's climate and infrastructure create specific challenges. Load shedding causes unexpected power cycles. Rising temperatures in server rooms stress equipment. Fibre backhaul connections occasionally degrade without obvious signs. And when your UniFi access points lose contact with the controller, the whole network feels broken—even though individual components often work fine.
We've also noticed that many Sandton businesses run UniFi without proper initial commissioning. Access points are installed, a password is set, and people assume it works. That's when problems emerge: weak channel planning, overlapping SSIDs, poor placement of controllers. Six months later, someone notices drop-outs in the boardroom.
The repair assessment we run costs from R599 and includes network diagnostics, controller status checks, and a clear explanation of what's degraded. Most jobs require only reconfiguration, not replacement.
Common UniFi Problems We See in Our Workshop
Controller Connectivity Loss
Your access points light up but show "disconnected" in the UniFi interface. This usually means the controller—the brain of your network—has lost contact with the access points. The fix often involves rebooting the controller and checking network routes. If your controller runs on a local server or Raspberry Pi, a power failure during load shedding might have corrupted its database.
We check controller logs first. Most customers don't realise their controller is trying to reach access points on a different subnet, or firewall rules are blocking communication on port 8080. A simple network audit finds this within minutes.
Weak Signal or Intermittent Drops
You're sitting in your Sandton office with a strong Wi-Fi signal, but video calls stutter. This points to RF interference or overcrowded channels. The 2.4 GHz band in busy areas like Sandton is often crammed with neighbouring networks. Our workshop uses a spectrum analyser to map channel occupancy and recommends changes that immediately improve throughput.
We've also found that access point placement matters far more than people expect. A UniFi AP mounted in a metal ceiling bracket won't perform like one with clearance. We reposition equipment and see drop-out rates fall from 15% to near zero.
Slow Internet Despite Strong Signal
Your speed test shows 50 Mbps down, but browsing feels laggy. This usually isn't a UniFi problem—it's a WAN issue. We check your fibre or fixed-line connection directly and compare it to speeds through the UniFi network. If the gateway (your modem or router feeding UniFi) is throttling, we identify it and escalate to your ISP.
How We Troubleshoot at ZA Support
When you bring a network issue to our Hyde Park workshop, our process is methodical:
For more complex issues like liquid damage affecting network equipment or failed PoE injectors, we extend our service to component-level repair. We've also written guides on logic board repair for customers who've had networking devices fail due to power surge damage.
Preventive Maintenance Saves Money
Most UniFi problems are preventable. We recommend:
We offer support packages starting at R599 per assessment, with ongoing monitoring available. Most customers find that a single professional audit—and our recommendations—save months of frustrating drop-outs.
Getting Help in Sandton
If you're experiencing UniFi problems, you have options. If your issue is straightforward—a forgotten password, access point not booting—a call to Ubiquiti support may be enough. But if you need someone to walk your office, test your network under load, and optimise it for Johannesburg's specific environment, that's where we step in.
Our team at ZA Support has fixed networking issues for businesses across Sandton, Rosebank, and the greater Hyde Park area. We carry replacement access points and PoE injectors. We can often resolve issues the same day. Repairs and upgrades come with up to a 3-year warranty, and we're transparent about pricing from the start.
Book online at zasupport.com/book to schedule a network audit, or WhatsApp us on 064 529 5863 with details of what's happening. We typically respond within an hour on weekdays.

Frequently Asked Questions
Q: How much does UniFi troubleshooting cost in Johannesburg?
Our initial assessment is R599 and includes a full network audit, controller diagnostics, and a written report with recommendations. If you need us to implement fixes—such as firmware updates, channel optimisation, or access point repositioning—we quote those separately. Most jobs fall between R1,200 and R3,500 depending on network size.
Q: Can I troubleshoot UniFi myself?
You can try basic steps: restart the controller, reboot access points, and check that all devices are on the same subnet. But channel planning, interference analysis, and performance optimisation require specialist tools. If you've spent more than an hour on the issue, it's worth bringing in someone who can use a spectrum analyser and load-test your network properly.
Q: What if my UniFi equipment is damaged, not misconfigured?
We repair and replace PoE injectors, damaged access points, and failed controllers. If a power surge or liquid damage has affected your equipment, bring it in. We diagnose the failure and advise whether repair or replacement makes sense. Most jobs are repairable at component level.
Q: How long does a network audit take?
A basic audit of a small office (up to five access points, 30 devices) takes 45 minutes to an hour. Larger deployments may take two to three hours. We usually complete the work and have you back online the same day.
Q: Do you offer ongoing network monitoring?
Yes. We offer quarterly check-ups and can set up alerts on your UniFi controller to notify us of issues before you notice them. This is popular with businesses in Sandton that depend on reliable connectivity for client-facing work.
Q: What's your warranty on network repairs?
Component repairs and replacements carry a three-year warranty. If an access point we've repaired fails again within that period, we fix it at no cost (excluding accidental damage or water exposure).
