Why Is Wi-Fi Connected but Internet Not Working?

If your Wi-Fi shows connected but the internet does not work, your device reached the router but data cannot travel beyond it. The usual causes are a DNS failure, an internet provider outage, a stuck router, an expired IP lease, or security software blocking traffic. Test another device first: if it also fails, the router or provider is at fault, not your device.

Why this happens

The most common cause is DNS not working. DNS turns website names into server addresses, and if it stalls, pages fail to load even though the connection is live.

Other frequent causes are an outage at your internet provider, a modem that lost its provider signal, or a router that has been running too long and needs a reboot.

Less often, an expired or duplicate IP address, a firewall, an antivirus, or a VPN blocks traffic, or the router's date and time are wrong, which breaks secure connections.

Is this normal?

Short outages happen to everyone and usually clear on their own or after a reboot. A pattern that repeats daily or lasts a long time points to a hardware, configuration, or provider problem worth fixing.

Does it cause any problems?

Yes. Nothing that needs the internet will work, including browsers, email, streaming, and cloud apps. Local tasks like printing or transferring files between devices on the same network can still work.

How to fix or check it

1. Try a second device on the same Wi-Fi to see whether the problem is one device or the whole network.
2. Restart the modem and router: unplug both, wait about a minute, power the modem first, then the router.
3. Windows: run ipconfig /flushdns, then ipconfig /release and ipconfig /renew in Command Prompt.
4. Mac: go to System Settings, Network, Wi-Fi, Details, TCP/IP, and Renew DHCP Lease.
5. Try changing your DNS to a public option such as 8.8.8.8 and 8.8.4.4, or 1.1.1.1, on the device or router.
6. Temporarily disable any VPN, firewall, or antivirus to rule them out.
7. Phone: toggle Airplane mode, or forget and rejoin the network.
8. Connect a computer to the modem by cable to check whether the line itself is down.
9. If every device fails, check your provider's outage page or contact them.

Frequently asked questions

How do I know if it is my router or my provider?

Plug a computer directly into the modem with an ethernet cable. If the internet works that way, the router is the problem. If it still fails, the provider or the line is the issue.

Why do pages load slowly then fail?

That pattern often points to a weak signal, an overloaded connection, or a failing DNS server. Changing DNS and moving closer to the router are good first tests.

Can wrong date and time break the internet?

Yes. Secure sites check certificates against the clock, so a badly wrong date can block many pages. Set the device and router to update time automatically.
