Wi-Fi Connected but No Internet: Find Which Link Is Broken, Then Fix It

“Connected, no internet” is one of the most annoying network messages because it sounds contradictory. It is not: your device is connected to the router, but the router — or something between your device and the wider internet — is not passing traffic on. Fixing it quickly is mostly a matter of finding which link is broken. This guide starts with a two-minute test that tells you where to look, then goes through the fixes for each case, from the provider’s line down to a single phone.

What “Connected, No Internet” Actually Means

A home connection has two links. The first is between your device and your router: Wi-Fi or a cable. The second is between your router and your internet provider: the modem, the line and the provider’s network. The Wi-Fi icon only tells you about the first link. When Windows says “No internet”, an iPhone shows “No Internet Connection” under the network name or Android shows “Connected, no internet”, the device has checked the second link — it tried to reach a test address on the internet — and failed.

There is also a third, sneakier failure: the connection works, but the device cannot translate names into addresses. When DNS fails, nothing loads by name, yet the network looks alive. We will come back to it.

Step 1: One Device or All of Them?

Before changing any setting, check two things.

Do other devices have internet? Pick up a second phone or laptop on the same Wi-Fi and open a website. If it works, the problem is with the first device — skip to the one-device section. If nothing on the Wi-Fi can get online, the problem is the router, the modem or the provider.

Does the router’s settings page open? On the affected device, open 192.168.0.1 or 192.168.1.1 (or the address on your router’s label). If the page loads, the first link — device to router — is fine, and the trouble is on the router’s internet side. If it does not load either, the device is not really talking to the router.

These two answers point to the right section and save you from resetting things that were never broken.

When No Device Can Get Online

If every device is affected, start with the cheapest checks and work towards the router.

Check for an outage. Look at your provider’s status page or app from mobile data. Area outages are common and no amount of restarting fixes them.

Look at the modem’s lights. Most modems and provider gateways have an Internet, Online or WAN light. Off, red or blinking for minutes usually means the line or the provider. If the modem and router are separate boxes, also check the cable between them.

Restart in the right order. Unplug the modem and the router. Plug the modem back in first and wait until its online light is steady — often two to five minutes — then plug in the router. Restarting them in the wrong order can leave the router without an internet address.

Read the router’s status page. In the router settings, the Status, WAN or Internet section shows whether the router got an internet address from the provider. An address of 0.0.0.0 or “Disconnected” confirms the problem is between the router and the provider. If you reset the router recently, it may simply be missing the provider’s login: many DSL and fibre connections use PPPoE with a username and password from your contract, and a factory reset erases them.

Check for a second router in the chain. If you replaced your provider’s gateway with your own router, some cable providers only hand out an address to the hardware they have registered; their support can update it. If you put your own router behind the provider’s gateway, the gateway still has to be online for anything to work.

When Only One Device Has No Internet

When other devices work fine, the router and the line are healthy, and the fault is in the device’s own connection settings. Try these in order; most cases end in the first three.

1. Turn Wi-Fi off and on, or switch airplane mode on for ten seconds and off again.
2. Restart the device. It clears stuck network services and renews its address.
3. Forget the network and join again with the password. This throws away a bad saved profile. If you do not remember the password, find it on another device first.
4. Turn off VPNs, proxies and security apps for a test. A VPN that lost its connection blocks all traffic by design; some antivirus suites do the same when their filter breaks.
5. Check the date and time. A clock that is badly wrong makes secure websites fail, which looks like no internet.
6. Look at the device’s IP address. If it starts with 169.254, the device did not get an address from the router at all. That points to a Wi-Fi problem between the two, a router that has run out of addresses, or a block list on the router — see who is connected to your Wi-Fi to check whether the device was blocked. You can see your device’s local address with What Is My Local IP instructions.

Test DNS separately. If pages fail by name but the network seems up, DNS is the suspect. On a computer, run ping 8.8.8.8 in a terminal and then ping google.com. If the first answers and the second does not, the connection works and only name lookup is broken. Set the device’s DNS to a public resolver such as 1.1.1.1 or 8.8.8.8, or change it on the router for the whole home.

Public Wi-Fi is a special case. In hotels, airports and cafés, “connected, no internet” usually means a sign-in page (captive portal) has not appeared. Open any plain website, such as http://example.com, to trigger it.

Fixes on Windows

Windows 11 has a Network and Internet troubleshooter in the Get Help app that runs diagnostics automatically and fixes common problems — worth one run before anything manual. If it does not help, these commands in a Command Prompt opened as administrator cover most remaining cases:

ipconfig /release
ipconfig /renew
ipconfig /flushdns
netsh winsock reset

The first two get a new address from the router, the third clears cached name lookups, and the last resets the network stack; restart afterwards. If a Windows update or driver change preceded the problem, update or roll back the Wi-Fi adapter driver in Device Manager. The last resort is Network reset in Settings → Network & internet → Advanced network settings, which removes and reinstalls all network adapters — you will need to rejoin Wi-Fi networks afterwards.

Fixes on iPhone and Android

On an iPhone or iPad, tap the network name in Settings → Wi-Fi: iOS shows details about the problem there. Apple’s own steps are to make sure Auto-Join is on, restart the device and the router, and as a last step reset network settings in Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings, which also removes saved Wi-Fi passwords and VPN settings. If the problem appeared on one particular router, try switching Private Wi-Fi Address off for that network — some routers with MAC-based rules do not recognise the changing address.

On Android, open the network in Settings → Network & internet → Internet, choose Forget, and join again. Check Settings → Network & internet → Private DNS and set it to Automatic or Off; a custom private DNS provider that is unreachable breaks every website while Wi-Fi shows as connected. Menu names differ between manufacturers, and on Samsung phones the same options are under Connections.

Symptoms and Likely Causes

When to Call Your Provider

Call when the modem’s online light stays off after a proper restart, when the router reports no internet address from the provider, or when the problem repeats at the same time every day. Have the model of your modem or gateway ready and mention what you already tried — the restart order and the light colours save a lot of time on the phone. If your provider’s gateway is involved, ask them to check the line and re-provision the device; that is something only they can do.
