What should I check first for wi‑fi connected but no internet?

Start by validating the scope of the issue: check whether it affects one device, one room or the whole connection, then compare Wi‑Fi and Ethernet where possible.

Can Wi‑Fi cause wi‑fi connected but no internet?

Yes. Weak Wi‑Fi, interference, router placement and device limitations can cause many broadband symptoms even when the line itself is working.

When should I contact my provider?

Contact your provider if the problem affects Ethernet as well as Wi‑Fi, router or ONT lights show a service fault, or repeated tests prove the issue is outside your home network.

Likely causes

Most Common Causes

The same symptom can have several different causes. Start with the causes below, then use the validation steps to prove which one is most likely.

Router has Wi‑Fi but no broadband

Your device can connect to the router even when the router itself has lost the internet service.

DNS or browser problem

Apps may work while websites fail if DNS, browser cache or security software is the issue.

Device network fault

A single phone, laptop, TV or console may have a bad saved network, stale IP lease or software issue.

Provider outage

If every device has no internet and router service lights look wrong, the fault may be outside your home.

Steps to Narrow Down the Root Cause of the Issue

Work through these checks in order. Change one thing at a time so the result tells you something useful.

1
Test another device on the same Wi‑Fi network.
2
Open a browser and try more than one website, then try an app.
3
Check router and ONT lights before restarting anything.
4
Restart the problem device, then reconnect to Wi‑Fi.
5
Run a speed test if any connection returns, and compare Wi‑Fi with Ethernet if possible.
6
Check provider status if every device is affected.

Fix

Problem Resolution

Apply the fix that matches the cause you validated. If the issue is proven outside your home network, gather evidence before contacting your provider.

Forget and reconnect to Wi‑Fi

Remove the saved network on the problem device, then reconnect with the correct password.

Restart router and device

Restart the device first, then the router if multiple devices are affected.

Try Ethernet or another room

A successful Ethernet test means the broadband service is alive and the issue is likely Wi‑Fi or device related.

Escalate if the broadband service is down

Contact your provider if all devices fail, router/ONT lights indicate a fault, or the provider status page shows an outage.
