💡 3 Ways to Fix It

There are 3 technologies built to solve this: WiFi extenders, WiFi Mesh systems, and wired access points. They all extend your coverage, but in very different ways. This guide explains each one, compares them side by side, then walks you through setting up WiFi Mesh from scratch.

A WiFi extender, also called a booster or repeater, picks up your router's existing signal and rebroadcasts it further into your home. It plugs into any wall outlet and creates a 2nd, separate WiFi network with a different name, so your phone does not switch to it automatically. You have to manually connect as you move into the extended area.

💡 Can you use more than 1 WiFi extender?
You can, but the problems multiply. A second extender means a third network name, more manual switching, and more interference. If you find yourself thinking about a second extender, that's the sign to switch to WiFi Mesh instead.

WiFi Mesh is a home networking system where 2 or more units, called nodes, work together to broadcast 1 WiFi network across your entire home. 1 node connects to your broadband modem and acts as the router. The others sit in different rooms, each picking up where the last one left off so the signal stays strong everywhere, even behind Singapore's steel-reinforced concrete walls.

💡 The Key Difference from an Extender

1 WiFi name. 1 password. Your devices switch between nodes automatically as you move room to room. No manual switching, no dropped calls, nothing to do on your end.

Think of it like a relay team. The main node connects to your internet modem by cable. The satellite nodes spread out around your home, each talking to the nearest node, not directly to the main router.

With a regular router or extender, every device has to reach back to one point. The further you are, the weaker the signal. With WiFi Mesh, the node in your bedroom only needs to talk to the node in the hallway, which talks to the main node in the living room. The distance each signal travels is short, so the strength stays high.

💡 Why Singapore homes need WiFi Mesh more than most?
HDB and condo walls are steel-reinforced concrete. A router delivering 300 Mbps at 2 metres typically drops to under 50 Mbps after passing through just 2 of these walls. For homes with 3 or more rooms, WiFi Mesh is the baseline for reliable coverage.

A WiFi access point (AP) connects to your router by ethernet cable and broadcasts WiFi from that fixed spot. Data travels by wire all the way to the AP, then wireless only for the last short hop to your device. This gives APs the highest possible speed and lowest latency of the 3 options, but it requires ethernet cabling already in your walls.

💡 Best of Both Worlds
Most WiFi Mesh systems support wired backhaul. If your BTO flat already has ethernet ports in each room (standard since around 2014), plug every mesh node into the wall port. You get access-point-level speed with the convenience and app management of WiFi Mesh.

Stage 1 of 3 - Plan

How Many Mesh Routers Do I Need?

💡 Start with 2 nodes. Walk around after setup and run a speed test in each room. Only add a third if a room is noticeably weak. Too many nodes placed too close together cause devices to switch constantly, which slows everything down.

Stage 2 of 3 - Place

Where to Place Your Mesh Nodes?

Keep nodes at least 1 metre away from microwaves and mirrors. Microwaves share the 2.4GHz frequency and cause interference. Check our WiFi optimisation guide for more tips.

Stage 3 of 3 - Connect

How to Connect Mesh to Your Router?

Path AReplacing Your Router

Before you start: ONT must be on. Ethernet cable ready. Download the brand's app. Unplug the ONT for 30 seconds first so it assigns a fresh IP to the new node.

Path BKeeping Your Existing Router

Use this if your router handles IPTV or a home phone line you can't disable. After setup, turn off WiFi on the old router. Running both networks simultaneously causes devices to bounce unpredictably.

Path CBTO Wired Backhaul

Most HDB BTO flats built since 2014 have ethernet pre-run to every room via a patch panel in the DB box. Wired backhaul means node-to-node communication runs over cable, giving full speed with zero wireless overhead.

Not sure if you're wired?
Check inside the DB box near your front door. A patch panel with multiple ethernet ports means your flat is pre-wired.

🛠️ Rather Not DIY?

StarHub plans include free installation by Hub Troopers. They handle the wiring, positioning, and testing. Find out more here.

✕ A satellite node won't pair

Move it right next to the main node for pairing, then relocate it once connected. If it still fails, unplug both nodes for 30 seconds, plug them back in, and try again. Check the app store for firmware updates before re-attempting.

✕ Slow speeds near a satellite

The wireless backhaul between the satellite and the main node is too weak, usually because there are too many walls in between. Move the satellite closer, reducing the wall count to 1 or 2. If your home has ethernet ports, switching to wired backhaul fixes this immediately.

✕ Devices won't roam between nodes

The most common cause: your old router is still broadcasting WiFi alongside the mesh system, so your devices bounce between the 2 networks. Disable WiFi on the old router entirely and let the mesh handle everything. If you still need the old router for IPTV or VoIP, keep it connected but turn off its wireless radios.

✕ Main node overheats in the DB box

The DB box is small and enclosed, and routers generate heat. If your node gets hot and starts dropping connections, move it out of the DB box to an open area like the TV console. Run an ethernet cable from the ONT (which stays in the DB box) to the node's new location, and leave the DB box door slightly open for airflow around the ONT.

A mesh extender is a satellite node in a WiFi Mesh system: the unit you place in a second or third room to extend the network. Different brands use different names. NETGEAR calls them satellites, Google calls them points, TP-Link calls them Deco units. They all work the same way. A mesh extender shares the same network name as the main node, uses a dedicated backhaul band, and enables seamless roaming. This is different from a traditional WiFi extender, which creates a separate network, cuts speed by roughly half, and requires manual switching.

No, not if the system is set up correctly. A tri-band WiFi Mesh system reserves one band entirely for node-to-node backhaul, so the bands your devices use stay clear. The scenario where mesh slows things down is when nodes are placed too far apart. Weak wireless backhaul is the speed killer, not the technology itself.

Yes. The main mesh node takes over the job of your router. Connect it to your ONT and it manages the entire network. Switch off your old router or disable its WiFi radios to prevent interference. If your old router handles IPTV or a home phone line, keep it connected but turn off its wireless radios only.

No more than two rooms apart, or roughly 30 feet (9 metres) in a straight line. In Singapore homes with concrete walls, keep to a maximum of two walls between any two nodes. The app's signal test or the node's LED will tell you. Amber or red means move it closer.

For studios and 2-room flats, a single good router is usually enough. WiFi Mesh makes a real difference in 3-room flats and larger, where the signal must pass through multiple concrete walls. Even a WiFi 6 router struggles to cover a 5-room HDB reliably. Singapore's reinforced concrete reduces effective range significantly compared to the open-plan layouts most specs assume.

WiFi 6 handles most homes well and costs less. WiFi 7 adds a 6GHz band with less interference and higher throughput per device. If you're on a 5Gbps or 10Gbps broadband plan and want to future-proof, WiFi 7 is worth it. For most households on 1Gbps plans, WiFi 6 is more than sufficient.

It depends on your home. WiFi 6 has a rated range of around 107 sqm in open conditions, roughly a 5-room flat. In practice, Singapore's concrete walls and furniture reduce that significantly. If your router already covers every room, you don't need mesh. If bedrooms are still weak, a WiFi Mesh node fixes what the router alone can't reach. For multi-storey homes, mesh is almost always the right answer.

Yes. Connect the main mesh node's WAN port to a LAN port on your StarHub router, disable the router's WiFi radios, and run the mesh app setup. Alternatively, StarHub's WiFi 7 routers support EasyMesh, so you add compatible mesh nodes directly without needing a separate main mesh node.

For reliable performance, yes. While the EasyMesh standard allows different brands to work together in theory, mixing brands typically means losing seamless handoff, smart traffic routing, and unified app management. Stick to the same brand and product line.

Yes. WiFi Mesh systems broadcast standard 2.4GHz and 5GHz bands that all WiFi-capable devices connect to regardless of age. Older devices won't use WiFi 6 or WiFi 7 features, but they connect and work normally. You don't need to replace your devices to benefit from better coverage.
