Full Wi-Fi bars but nothing loads? Find out whether it is your device, your router, or your provider.
Quick fix⏱ 5–20 minWindowsMaciPhoneAndroid
"Connected, no internet" means your device is talking to your router perfectly well, but the router is not getting through to the wider internet — or your device is not getting the addressing information it needs to reach it.
The first job is to work out how widespread the problem is. If every device in the house is offline, look at the router and your provider. If only one device is affected, the fix is on that device.
Try these first — 30 seconds each
[ ]Check another device on the same Wi-Fi. All offline points to the router or provider; one offline points to that device.
[ ]Look at the router lights — a red, orange, or flashing internet/WAN light usually means the connection from your provider is down.
[ ]Check your provider's service status page or app using mobile data.

1
Restart the modem and router properly
Unplug the power from both (or the single combined box), wait a full 60 seconds, then plug the modem in first and wait until its lights settle before powering the router. This clears stuck sessions and makes the router request a fresh connection from your provider.
2
Forget and rejoin the network
On the affected device, open Wi-Fi settings, choose the network, select Forget, then reconnect with the password. This clears saved settings that may have gone stale, such as an old IP address.
3
Check for a sign-in page
On hotel, café, or office Wi-Fi, a login page must be accepted before the internet works. Open a browser and visit a plain http address such as neverssl.com to trigger it.
4
Renew the IP address and flush DNS
Windows: open Command Prompt and run "ipconfig /release", then "ipconfig /renew", then "ipconfig /flushdns". Mac: System Settings → Network → Wi-Fi → Details → TCP/IP → Renew DHCP Lease. Phones: toggle airplane mode on for 10 seconds, then off.
5
Try a different DNS server
If apps connect but websites will not load by name, DNS may be failing. Set your device's DNS to a public service such as 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google) in its network settings, or change it once on the router for the whole house.
6
Reset network settings on the device
As a last step on a single device: Windows — Settings → Network & internet → Advanced network settings → Network reset. iPhone — Settings → General → Transfer or Reset → Reset → Reset Network Settings. Android — Settings → System → Reset options → Reset Wi-Fi, mobile & Bluetooth. You will need to re-enter Wi-Fi passwords afterwards.
Platform notes
Windows
VPN software and some security suites install network filters. If the problem started after installing one, disable or uninstall it to test.
iPhone
Private Wi-Fi Address and Limit IP Address Tracking are occasionally incompatible with older routers. Toggle them off for that network (tap the ⓘ next to it) to test.
Stop it happening again
Keep router firmware up to date — many providers do this automatically, but third-party routers need checking.
Place the router somewhere ventilated; overheating routers drop connections.
Save your provider's support number in your phone for outages.
When to get professional help
If all devices are offline after a full restart and the provider reports no outage, call them — they can test the line to your home remotely. Ask them to check signal levels on the modem.
