Quick Answer
When Wi-Fi coverage is weak, add a mesh node or reposition the router before replacing it: most dead zones come from placement and walls, not a faulty router. A 2-pack Wi-Fi 6 mesh kit at R2,500 to R3,500 fixes coverage better than a single new R1,500 router.
Coverage Is Usually A Placement Problem
A weak signal in the back bedroom rarely means the router is broken. SA homes with brick walls and double storeys block 5GHz signal fast. First, move the router to a central, elevated, open spot and update its firmware. A router buried in a TV cabinet or shoved against an outside wall loses much of its reach. If repositioning lifts a far-room signal from 2 bars to 4, you have saved the cost of new hardware.
If coverage is still patchy after good placement, the fix is more coverage, which means mesh, not a single stronger router.
When To Add Mesh Or Replace
A 2-pack Wi-Fi 6 mesh kit at R2,500 to R3,500 covers a flat, and a 3-pack at R4,000 to R5,500 covers a double-storey house, holding 300Mbps to 800Mbps near each node. A single new router rarely beats mesh for coverage because one box cannot punch through multiple walls. Replace the router outright only if it is old, overheats, or lacks 5GHz; otherwise add nodes to extend it.
Cheaper Fixes Before A Full Kit
A wired backhaul to a single access point in a dead zone, using an Ethernet run for R200 to R500, can fix coverage without a full mesh kit. A powerline adapter pair around R600 to R1,000 carries the network through your wiring to a far room. Keep the 2.4GHz band enabled for range and reserve 5GHz for nearby fast devices.
FAQ
Why is my Wi-Fi weak in some rooms?
Brick walls, distance, and a poorly placed router block the signal, especially on the 5GHz band. Centring and elevating the router fixes many dead zones before you spend on anything.
Is a mesh kit or a new router better for weak coverage?
A mesh kit is better for coverage because multiple nodes blanket the home, while one router struggles through walls. A 2-pack at R2,500 to R3,500 covers a flat and outperforms a single new router for reach.
Can I fix a dead zone without buying a mesh kit?
Yes. An Ethernet run to a spare access point or a powerline adapter pair at R600 to R1,000 can carry the network to a far room. These are cheaper than a full mesh kit for a single problem zone.
move the router to a central, elevated spot and re-test the weak room; placement alone fixes a surprising number of coverage complaints for free.
