Will a Wi-Fi 7 router make my fibre line faster?

No. The wireless standard governs the link between your devices and the router, and it cannot deliver more than your line brings into the house. What changes is everything on the local side: transfers between your own machines, how the network holds up with twenty devices connected, and latency when several people are streaming while you play.

Can I actually run a 320MHz channel in South Africa?

Only one fits. The licence-exempt lower 6GHz allocation of 5925 to 6425MHz has room for a single 320MHz channel, and using it means you and every neighbouring network in range are competing for the same slice with nowhere to move. Markets that opened the full band can field three. Treat 160MHz as the working setting and the wider channel as a lab number.

Do my phone and laptop need to be Wi-Fi 7 as well?

To use the new features, yes, since multi-link and the wider channels need both ends. Older devices still connect and still keep their own limits. There is a second-order benefit though: moving your newest devices onto 6GHz clears airtime on 5GHz, so the older laptop and the smart TV often behave better than they did before.

Do I still need the router my internet provider supplied?

You keep the fibre termination unit, and usually the provider's box goes into bridge or pass-through mode so the new router handles the connection and the network. Running both as routers creates a double layer that breaks port forwarding and console connectivity. If the provider box has to stay in charge, at least switch off its wireless so you are not broadcasting two overlapping networks.

Is a mesh set better than one strong router?

A single unit placed centrally and high beats a mesh placed badly, and it is cheaper. Mesh earns its cost in double-storey houses, long single-level layouts and homes where the fibre enters at one end. Where it goes wrong is nodes that relay over the same band they serve clients on, which halves throughput at every hop, so look for a wired backhaul option or a node radio kept aside for the link.

Wi-Fi 7 routers for South African homes and offices

What the Standard Adds, and What Local Spectrum Allows

Wi-Fi 7 is the 802.11be generation, and its headline features are wider channels, denser modulation, multi-link operation and preamble puncturing. Three of those four do useful work in a South African home. The fourth is limited by how much 6GHz spectrum the regulator has opened.

ICASA licence-exempts the lower 6GHz band only, from 5925 to 6425MHz, and has held the upper portion back for future mobile use. Five hundred megahertz leaves room for exactly one 320MHz channel, against three in markets that opened the whole band, which makes the widest channel a headline rather than a plan.
