Wi-Fi that reaches. Internet that stays up.

Wi-Fi assessment and improvement

Dead spots, video calls that freeze, a router that "needs a restart" every week? Most Wi-Fi problems come from where the equipment is and how it's set up, not from the internet line. An assessment finds out which.

What the assessment covers

• Signal survey: we measure signal strength and speed room by room, and mark the weak spots on a floor plan.
• Interference check: neighbouring networks, crowded channels and devices that drown out your Wi-Fi.
• Equipment and cabling review: your router, extenders, switches and network points, and whether your ISP's router is holding you back.
• Internet line test: so we can tell you honestly whether the problem is the Wi-Fi or the line.
• A written report: what's wrong, what to fix first, and a fixed-price quote. Sometimes the fix is just moving or reconfiguring what you already have.

Improvement work

• Access points placed and wired for full coverage, with sensible channel and power settings.
• Separate networks for staff, guests and devices such as cameras, TVs and smart-home gear.
• Backup internet with automatic failover (see below).
• Remote monitoring of UniFi networks, so we often spot problems before you do.

Multiple WAN and automatic failover

"WAN" is your internet connection. A multi-WAN router connects to two (or more) internet lines at once, for example fibre plus an LTE/5G router, or fibre from two different providers.

• Failover: when the main line drops, traffic moves to the backup within seconds and moves back when the main line recovers. Card machines, VoIP phones, Teams calls and cloud apps keep working.
• Load balancing: both lines are used together, spreading traffic across them. Useful when one line alone isn't enough.
• Different paths matter: two fibre lines on the same street cable fail together. A wireless (LTE/5G) or different-provider backup gives real redundancy.
• Power matters too: during loadshedding the fibre box (ONT), router and switch need a small UPS or DC backup, otherwise failover has nothing to fail over to.

The UniFi Cloud Gateway Ultra handles fibre plus an LTE backup for a home or small office. The Cloud Gateway Max has five 2.5 GbE ports, any of which can be a WAN, for busier offices. Both alert you in the UniFi app when a line goes down.

Getting good signal through walls

South African homes and offices are hard on Wi-Fi: double brick, concrete slabs, foil roof insulation and burglar bars all block signal. Here's what actually helps:

• Know your bands. 2.4 GHz travels further through walls but is slower and crowded. 5 GHz and 6 GHz (WiFi 6E/7) are much faster but weaken quickly through brick and concrete. Good coverage puts a fast signal close to where people work.
• Know what blocks signal: concrete and brick walls, floor slabs, metal (doors, burglar bars, fridges, filing cabinets), mirrors, foil-backed insulation, and water (fish tanks, a full room of people).
• More access points, not a stronger router. One "powerful" router in a corner can't push through three brick walls, and your phone can't shout back that far anyway. Two or three access points at normal power, one per zone, beat one router at full blast.
• Wire them where you can. Each access point connected by a network cable (and powered over it with PoE) gives full speed everywhere. Wireless mesh is the fallback where cables can't go, because each wireless hop costs speed.
• Ceiling, central and in the open. Mount access points on the ceiling in the middle of the area they serve, not in a cupboard, behind the TV or on the floor.
• Outside areas get outdoor gear. Signal from inside rarely makes it through an exterior wall well. A weatherproof unit like the UniFi Mesh covers patios, gardens and outbuildings properly.
• One network name. With UniFi, all access points share one Wi-Fi name and devices move between them as you walk around. No more "Office_EXT".

A simple UniFi Protect camera setup

UniFi Protect records your cameras on a recorder in your own building and lets you watch live or recorded video in the UniFi Protect app. A typical small-office or home setup:

• UniFi Protect NVR Instant: the recorder. It runs UniFi Protect and stores the footage on site.
• UniFi Switch Lite 8 PoE: powers up to four cameras over their network cables, so no plug points are needed at the camera.
• 2 × G5 Turret Ultra for the front door, reception or passages.
• 2 × G5 Bullet for the driveway, gate or back yard.

Already have a Cloud Gateway Max? Add an NVMe SSD and it can run Protect itself, without a separate recorder. Installation, cabling and mounting are quoted separately after a quick site check.

Why local, licence-free recording is more secure

• Your footage stays on your premises. It isn't uploaded to a third-party cloud, so a breach at a camera company can't expose your video.
• No licences, no subscriptions. No per-camera fees and no monthly cloud plan. You buy the hardware once and add cameras any time.
• Keeps recording when the internet is down, including when someone cuts your line, which burglars sometimes do. Cloud-only cameras stop recording when the internet stops.
• Cameras can be cut off from the internet entirely. We put them on their own network with no internet access, so a camera can't be hijacked from outside or quietly "phone home".
• Remote viewing is optional and encrypted through the UniFi app, protected by your UniFi account with two-factor sign-in. You can switch it off and keep the system fully offline.
• Protect the recorder: mount it out of sight in a locked cabinet with the router, on a UPS, so it keeps recording through loadshedding and can't simply be carried off.
