When you order fibre, the router is often an afterthought, until your Wi-Fi can’t reach the back bedroom. Most South African ISPs either include a router or sell you one, and the deal you pick (and where you put the thing) makes a real difference to your everyday experience. Here’s how fibre routers work and how to get strong, reliable Wi-Fi.
The ONT vs the router: two different boxes
There are usually two devices in a fibre setup. The ONT (Optical Network Terminal) is the box the fibre cable plugs into on your wall. It belongs to the network operator (the FNO) and converts light into a normal signal. The router then plugs into the ONT and creates your Wi-Fi and home network. The router is the part your ISP supplies or you buy. (Our jargon glossary defines both.)
Why it matters: the ONT determines your line speed; the router determines how well that speed reaches your devices. A great line behind a weak router is the most common cause of disappointing Wi-Fi.
Free-to-keep router deals
Many ISPs run promotions with a free router, sometimes free-to-keep, sometimes free-on-contract. Webafrica, for example, built much of its reputation on free-router offers, and most major ISPs run similar deals at times, especially around sales periods. The fine print is what counts:
- Free-to-keep versus free-on-loan: a loan router must be returned if you cancel, so check which you’re getting.
- Contract strings: a “free” router on a 24-month contract can carry a recovery fee if you leave early.
- Router quality: a basic bundled router is fine for a small flat but may struggle in a larger home (see mesh below).
Should you buy your own router?
For many homes the supplied router is perfectly adequate. But buying your own can be worth it if you want better range, more control, or features the basic unit lacks. A good third-party router (or mesh system) often outperforms the freebie, and it’s yours regardless of which ISP you’re with. The trade-offs:
| ISP-supplied router | Your own router | |
|---|---|---|
| Cost | Often free / bundled | Upfront purchase |
| Setup | Pre-configured, plug-and-play | You configure it (PPPoE details if needed) |
| Performance | Fine for small/medium homes | Can be much stronger |
| Portability | May be tied to the ISP | Keep it across ISPs |
If you do buy your own, check whether your ISP uses a PPPoE login. You may need to enter a username and password into the new router to authenticate the line.
Mesh and whole-home Wi-Fi
A single router in the lounge often can’t blanket a double-storey or wide home. Mesh Wi-Fi, where two or more linked units sit around the house, solves this by spreading the signal instead of relying on one box to reach everywhere. Many ISPs now offer mesh add-ons or bundles. If you have persistent dead spots, mesh usually fixes them more reliably than repeaters.
Getting good signal: the free wins
Before spending anything, try the basics, because placement alone often transforms Wi-Fi:
- Put the router central and high, out in the open, not in a cupboard, behind the TV or on the floor.
- Keep it away from microwaves, cordless phones and thick walls.
- Use the 5 GHz band for nearby devices (faster) and 2.4 GHz for range.
- Reboot occasionally, and keep the router’s firmware updated.
Remember: slow Wi-Fi often isn’t a slow line. If a speed test at the router is fast but your bedroom is slow, it’s a Wi-Fi coverage problem. See our fixing slow Wi-Fi guide before blaming your ISP.
Choosing a deal with the right router
When you compare fibre packages, weigh the router into the value. A genuinely free-to-keep, capable router can be worth more than a slightly cheaper plan with a flimsy one. Our best fibre deals guide factors this in, and because fibre is open-access you can switch ISP later and keep your own router.
Start by seeing which networks and ISPs reach you. Check fibre coverage and compare the live deals at your address, then pick the package, and router, that fits your home.
