# Wifi not working in Singapore: what to check first, what it costs, who to call Source: https://honestfix.cf-migrate-pulse-web.workers.dev/guides/wifi-not-working-in-singapore-what-to-check-first-what-it-costs-who-to-call · checked 15 Sep 2026 the Honestfix team · checked 15 Sep 2026 Most home wifi failures in Singapore are one of three things: the fibre or broadband service itself is down, the router has lost its connection to the provider, or the signal is not reaching the room you are in. Checking them in that order tells you whether you need your telco or a technician. ## What to check first Check the router first. TP-Link's guidance is to log into the router's web interface and check the WAN information on the router: a valid WAN IP means the router is connected to your provider, and 0.0.0.0 means it is not. That one reading splits the problem in half, and it is free. Then check how wide the failure is. Is it every device, or one? Every room, or one? Write the answer down before you call anyone. A provider who arrives already knowing that the router shows no WAN IP and that no device in the flat can connect will spend the visit fixing, not asking. Do not factory-reset the router as a first move. A reset wipes the provider settings your telco loaded, and on some fibre plans that turns a ten-minute fix into a service appointment. ## The likely causes, in order **The broadband service or the link to it (most common).** If the router has no connection to your provider, the fault is upstream of your home. Call your telco before you pay anyone to visit, because a service outage or a suspended account is not something a home IT technician can fix. Check the provider's app or outage page, and check that the optical network terminal by your door has its usual lights. **One device, not the network.** If one device cannot connect but the others can, the fault is on that device. TP-Link's advice is to check the TCP/IP settings on the particular device if all other devices can get internet from the router. A phone stuck on an old saved network, or a laptop with a manually set IP address, looks exactly like "the wifi is down" from where you are standing. **Coverage, not connection.** If the wifi drops in one room only, it is coverage, not a fault. TP-Link lists microwaves, refrigerators, ovens, Bluetooth devices, and other appliances that emit radio frequency interference, and says to place the router up high and away from obstacles. In a Singapore flat this matters more than people expect: routers end up in a store room or behind a TV console, and the bedroom at the far end of the corridor pays for it. **It was never as fast as the box said.** Rated router speed is not internet speed. TP-Link states that the rated figure is the maximum wireless associated/link speed the router can provide, the internal WLAN connection speed between the computer and the router, not the internet speed. If the complaint is "slow", establish what speed you actually pay for before treating it as a fault. ## When to call, and who Call your telco when the router shows no connection to the provider, when the optical network terminal shows a fault light, or when the whole block or estate is affected. That work is on their side of the wall and is usually covered by your plan. Call a home IT and wifi provider when the router is connected to the provider but the home network is not doing its job: dead spots across an HDB flat or a landed house, a mesh system that needs setting up properly, a network that needs to be rebuilt after a renovation, or wiring for access points. Stop if the fault involves the power point the router plugs into. A socket that sparks, smells of burning or trips the breaker is electrical work, not wifi work, and needs a Licensed Electrical Worker. Do not let a network technician open a power point. ## What it costs Ask two or three for a written quote instead. When you ask, give each provider the same description: home type and rough size, how many rooms fail, what the router shows, and whether you want the existing equipment tuned or new equipment installed. A quote for "improve wifi coverage" with no scope is not comparable to anything. Ask what the call-out fee is, whether it is waived if you proceed, whether hardware is quoted separately, and what happens if the fix does not hold. Mesh nodes and access points are hardware costs, not labour, and should appear on their own lines. ## Who to call, and how to judge them Home wifi work is not licensed work in Singapore, so there is no public register to check. Judge a home IT provider on a written scope, a stated call-out fee and a business you can verify instead. An ACRA registration confirms the business exists, nothing more. Prefer a provider who asks what your router shows before quoting. The ones who quote a mesh system sight-unseen are selling hardware, not diagnosis. ## Frequently asked questions **Why is my wifi not working when my phone data is fine?** Most home wifi failures in Singapore are one of three things: the fibre or broadband service itself is down, the router has lost its connection to the provider, or the signal is not reaching the room you are in. Checking them in that order tells you whether you need your telco or a technician. **How do I know if the problem is my router or my provider?** Check the router first. TP-Link's guidance is to log into the router's web interface and check the WAN information on the router: a valid WAN IP means the router is connected to your provider, and 0.0.0.0 means it is not. **Why is the wifi fine in the living room but dead in the bedroom?** If the wifi drops in one room only, it is coverage, not a fault. TP-Link lists microwaves, refrigerators, ovens, Bluetooth devices, and other appliances that emit radio frequency interference, and says to place the router up high and away from obstacles. ## Sources - [TP-Link, "Why cannot I access the Internet after installed the TP-Link router?"](https://www.tp-link.com/sg/support/faq/833/) (fetched 15 Sep 2026) - [TP-Link, "TP-Link Router Keeps Disconnecting?
