Why Does My Wi-Fi Say Connected but There Is No Internet?

Quick answer

Count how many devices are affected, then look at the modem lights. Every device failing plus a dark or blinking internet light points upstream to the provider or the modem. One device failing while others work points at that device's network settings, often a placeholder address it assigned to itself.

Separate the local network from the internet

Start with a simple test that needs no equipment. Try to open your router's own settings page from a device on the Wi-Fi, using the address printed on the router label. If that page loads, the local network is healthy and the fault lies beyond the router. If it does not load, the trouble is between your device and the router itself.

Next, count the affected devices honestly rather than from memory. Walk to a second phone, a tablet, or a computer and try to load something new on each. A whole-house failure and a single-device failure have almost nothing in common, and guessing wrong here leads to an hour of pointless resets.

Read the lights before restarting anything

Restarting first destroys the evidence, so read the equipment before you touch the power. Most modems have separate indicators for power, the incoming line, and internet or online status. A steady online light means the provider link is up and the problem is inside the house. An off or continuously blinking online light means the modem is not getting a usable service, which is an upstream matter.

Write down the light pattern exactly as you see it, including colors and whether each light is steady or blinking. Providers often diagnose from that description alone, and it saves repeating the whole story later. If you have a combined modem and router in one box, the same indicators are usually grouped together on the front panel.

A self-assigned address is a strong clue

Every device needs an address from the router to use the network. When it never receives one, it invents a placeholder that begins with 169.254 on Windows or is reported as a self-assigned address on a Mac. Seeing that is genuinely useful: it means the conversation between the device and the router failed, so the provider is probably not involved at all.

The usual causes are a router address service that has stopped responding, a saved network with a manually entered address from an old setup, or too many devices for the range the router hands out. Forgetting the network on the affected device and rejoining it clears most stale settings. If several devices show placeholder addresses at once, the router is the more likely culprit.

When pages fail but something else still works

Occasionally one app keeps working while new pages will not load at all. That pattern hints at name lookup, the step that turns a website name into an address. A single app holding an established connection can survive while every new request fails.

You can test this without changing anything permanent by opening a site you never visit on a phone using mobile data instead of Wi-Fi. If it loads on mobile data and fails on Wi-Fi, note that result and mention it when you contact the provider, since name service trouble is fixed differently from a dead line. Avoid changing name server settings on individual devices while you are still gathering information, because it makes the next test harder to interpret.

Restart in the right order, once

If the lights and address checks point at the equipment, restart in sequence rather than all at once. Power down the modem, then the router if it is a separate box, wait a full minute, bring the modem back first and let its lights settle completely, then bring the router back. Reversing that order often produces a router with no working connection behind it.

One properly sequenced restart is informative. Repeated restarts are not, and they can hide an intermittent fault that the provider needs to see in their own line records. If the problem returns within hours of a clean restart, that repetition is itself worth reporting.

When only one device is affected

A single failing device narrows things considerably. Check whether a VPN, security software, or a content filter is intercepting traffic, since any of these can leave the Wi-Fi indicator looking perfectly normal while blocking everything. Check the clock as well: a device with a badly wrong date can fail to establish secure connections, which looks exactly like no internet.

Also consider which network the device actually joined. Guest networks, neighboring networks with similar names, and extender networks all appear connected while behaving differently. Confirm the exact network name on the affected device and compare it with a device that works.

Details to gather before calling your provider

Note how many devices are affected and which ones, the modem light pattern, whether the router settings page opens, the address the affected device is using, whether mobile data works in the same room, the time the problem started, and anything that changed that day such as a power cut, a firmware update, a new device, or scheduled work in your area. Have your account details ready but never share passwords over chat or email.

When to ask an expert

Independent online help is most useful when the evidence is mixed: some devices working, intermittent recovery, or a setup involving extenders, mesh units, or a second router. It is also worth asking before you reset a router to factory settings, because that erases the network name, password, and any custom configuration. Line faults, equipment swaps, and outage confirmation still have to go through your provider.
