WiFi dead spots rarely spread evenly through a house. One bedroom drops out, the kitchen is patchy and the lounge is fine. The fix is to work room by room: move the router first, then add a WiFi extender, mesh unit or cable only where a room still struggles.
Quick answer: To fix dead spots, put the router as central and high as you can, then test each room with your phone. A WiFi extender placed halfway to one weak room is often enough. For several weak rooms, double storeys or outbuildings, mesh WiFi or a cabled access point gives steadier cover.
Walk the house with your phone and a free speed test app. Stand in each room for half a minute and note the result. You now have a map of where the problem really is.
In St Helena Bay many homes are long single storeys facing the water, with the router stuck at the front door where the fibre came in. As the team behind DStv installation in St Helena Bay, we find that causes most dead spots.
Before adding any gear, look at where the router sits. A router on the floor behind the TV cabinet, inside a cupboard or next to the DB board loses a lot of reach.
Lift it onto a shelf at chest height, out in the open, as close to the middle of the house as the cable allows. This one move often fixes two or three rooms at once.
The TV itself is worth a cable if it sits close to the router. A smart TV or decoder on a network cable streams better and frees up WiFi for phones. Our post on the DStv WiFi connector setup covers the decoder side.
The main bedroom at the end of the passage is the classic dead spot. Here a single WiFi extender works well, as long as it goes in the right place.
Plug it in about halfway, usually in the passage, where your phone still gets a decent signal from the router. Give the extender the same network name as the router if the app allows it, so phones switch over without fuss.
Technician tip: Face-brick and old stone walls in fishing cottages are thick. If the passage spot still tests weak, try a plug point one room closer to the router instead. A strong feed in matters more than being near the dead room.
Concrete floor slabs block WiFi more than most walls. Upstairs bedrooms in Shelley Point or Britannia Bay homes often show full bars on the stairs and nothing by the bed.
One extender on the stairs can help, but a two or three unit mesh network is usually the steadier answer for a double storey. We wrote more on strong WiFi in a double-storey holiday home if your house has two levels.
Kitchens are full of WiFi blockers. If the kitchen is the only weak room, moving the router a metre or two often beats buying anything. Watch out for:
Garages and braai rooms are usually through an outside wall, sometimes with a steel roller door. A wifi repeater rarely reaches far enough here. A short network cable to a small access point in the garage does the job properly.
If you have security cameras on WiFi in the garage or yard, those dead spots matter even more. A camera that drops out records nothing. Our CCTV camera installation work often includes cabling the cameras for that reason.

| Room | What usually blocks it | Best fix |
|---|---|---|
| Lounge or TV room | Router hidden in a cabinet | Move router up and out, cable the TV |
| End bedroom | Distance and thick walls | One extender halfway down the passage |
| Upstairs rooms | Concrete floor slab | Mesh unit on each floor |
| Kitchen | Fridge, metal and microwave | Shift the router a short way |
| Garage, braai room or flatlet | Outside walls and steel doors | Cabled access point |
People use the words loosely, so here is the plain version. A WiFi extender and a wifi repeater do the same job. They catch the router's signal and pass it on, which suits one weak room.
Mesh WiFi is a set of matching units that act as one network. It suits bigger homes and several dead spots. A cabled access point is the strongest of all, because the signal travels down a cable with no loss.
For most homes we visit, the answer is a mix. A better router spot, one cable to the far end and maybe one mesh unit upstairs. That is the kind of setup our WiFi and network cabling service puts in.
Safety first: Running cable through a ceiling means ladders, roof spaces and wiring you cannot see. Do not crawl into the ceiling yourself, especially in an older house. Leave cable runs above head height to a technician.
Holiday homes along the bay sit locked for weeks, then fill up with family in December. Salt air and long power cuts are hard on small network boxes left plugged in all that time.
Test every room on the first day of your stay, not the night guests arrive. If you are getting the house ready, our list for a holiday home TV-ready check pairs well with a WiFi walk-through.
If moving the router and one extender have not cleared every room, it is time for a proper look. We work across St Helena Bay, Stompneusbaai, Laingville, Vredenburg and Paternoster, and we test each room with you before we leave.
We also do new DStv installations, so TV and WiFi can be sorted in one trip. Call 079 754 5527 or book a visit online and we will quote first.

Start by moving the router to a high, open, central spot. Then test each room with your phone. Add a WiFi extender halfway to one weak room, or use mesh units or a cabled access point if several rooms or floors still struggle.
Distance from the router, thick brick or stone walls, concrete floor slabs and metal objects like fridges cause most dead spots. A router hidden in a cupboard or on the floor makes all of them worse.
One extender usually fixes one or two nearby weak rooms. It will not cover a whole double storey or a separate flatlet well. For several dead spots, a mesh system or a cable to an access point is more reliable.
For a larger home, yes. A mesh network uses matching units that work as one system, so phones move between them smoothly. For a single weak bedroom near the router, a good extender costs less and does the job.
Yes. We set up WiFi in holiday homes, estate houses and family homes around St Helena Bay and nearby West Coast towns. We map the weak rooms, then suggest the simplest fix and quote before any work starts.
