WiFi coverage & boosters
Proper access points placed where the signal is actually needed, so you get one network name and full strength from the gate to the back room.
WiFi that works in every room.
GreyX designs, installs and supports WiFi, networks and CCTV for homes and businesses around Sandton — and the work is as neat behind the wall as it is in front of it.
A real GreyX cabinet — not a stock photo.
The usual story
Full bars in the lounge. Nothing in the back bedroom.
Most “slow internet” is not a slow line. It is one router, sitting in the wrong place, trying to push a signal through brick, concrete, steel and a geyser.
So you buy an extender. Then another one. Then you call your ISP, who sends someone who tests the line, tells you the line is fine, and leaves.
That is usually the point at which people call us.
- Dead zones upstairs, in the cottage, or at the far end of the office
- Video calls that drop when you walk between rooms
- Streaming that buffers the moment everyone is home
- Cameras and smart devices that keep falling off the network
Signal demo
What we do
One team for the whole thing.
Coverage, cabling, cameras and the support afterwards. You are not chasing three different contractors when something stops working.
Data & LAN cabling
Hard-wired points for smart TVs, consoles, desks and access points, run back to a central, labelled data cabinet.
CCTV security systems
HD cameras with night vision, recording, and remote viewing from your phone — installed and configured, not just dropped off.
Laptop & PC repairs
Diagnostics, repairs and data recovery. Including the spilled-coffee emergencies people assume are beyond saving.
Cloud & IT support
Email, file storage, backups and the day-to-day support that keeps a small business running without an in-house IT person.
Network security
Guest networks kept separate from your own, sensible passwords, and firmware that actually gets updated.
Why people keep our number
We get called in after someone else has already tried.

Hardware we install
Ubiquiti and Reyee — supplied, installed and supported.
We are not a box shop. We specify the gear that suits the building, supply it as part of the job, and stand behind the install afterwards.
Ubiquiti UniFi U7 Pro
A WiFi 7 access point built for homes and offices with a lot of devices on the go at once. Available in ceiling, wall, in-wall and outdoor versions — including decorative covers that blend into the ceiling instead of standing out from it.
Reyee
A strong value option for straightforward homes, small offices and rental units, where the budget matters as much as the coverage.

Just so it is clear: this site is not an online shop. We do not sell hardware on its own over the counter — it comes as part of an installation, so that what you buy is what actually suits your building. Ask us for a quote and we will tell you what you need and what it costs.
Offices, shops & salons
Business networks that stay up through the trading day.
From open-plan offices to salons and shopfronts, we cable, mount and test the network around how you work — fit-outs before you move in, or work scheduled around your opening hours.
- Structured cabling back to a labelled cabinet
- Ceiling access points for even coverage across every desk
- A separate guest WiFi for visitors and customers
- CCTV and backup power in the same tidy cabinet
How a job runs
Four steps, no surprises.
We come and look
We walk the property, check where the signal actually falls over, and find out what you need it to do.
You get a quote
Written, itemised, and explained in plain language. You know what the hardware is and why it is on the list.
We install it properly
Cables routed and secured, cabinet tidy, access points mounted where they belong — and everything tested before we leave.
We stay reachable
If something changes or stops working, you call the same people who installed it. That is the part reviewers mention most.
Our work
Neat is not a nice-to-have.
A tidy cabinet is not vanity. It is what makes the next fault a ten-minute job instead of a two-hour one.
Where we work
Sandton and the north.
