When a laptop says it is connected but has no internet, it has joined the Wi-Fi but cannot browse properly. That is frustrating, but it narrows the fault.
The cause may be the laptop settings, router, provider line, DNS, IP address or a security tool blocking traffic.
Laptop connected, no internet checks
Run through the safe checks before you spend money, reset devices or start changing settings you may need later.
- Check whether your phone can browse on the same Wi-Fi.
- Move the laptop beside the router and test again.
- Forget the Wi-Fi network and reconnect.
- Restart the router properly once.
- Turn off VPN temporarily if you use one.
What the symptoms usually mean
Full signal bars, but nothing loads anywhere
Usually points to
The laptop has an address on the local network but no working route out to the internet, or no working name lookup. Signal strength tells you nothing about either.
Best next step
Check whether the laptop can reach the router itself. If it can, the local link is fine and the fault is beyond it, in DNS or the gateway settings.
It works on mobile hotspot but not on home Wi-Fi
Usually points to
The laptop's networking hardware is fine, which rules out a great deal. The problem is specific to the saved home network profile or to something the router is doing.
Best next step
Forget the home network entirely on the laptop and rejoin from scratch, so the saved profile is rebuilt rather than reused.
Everything worked until new security software was installed
Usually points to
Some antivirus and VPN products install a network filter driver that can block traffic while leaving the connection appearing healthy.
Best next step
Temporarily disable the security product's web-shield or firewall component to test. If traffic flows, the product needs reconfiguring rather than the network.

If phones work, focus on the laptop
If every other device can browse, the laptop may have a saved network problem, DNS issue, adapter driver fault or security setting blocking access.
If everything fails, focus on the router or provider
When every device says connected but nothing loads, the laptop is not the main issue. The router or broadband connection needs tested.
Why it can come and go
Intermittent no-internet faults can be caused by weak signal, router instability, IP conflicts, old drivers or provider dropouts. Patterns matter, so note when and where it happens.
Do not keep changing router settings for one laptop
If only one laptop has the issue, changing router-wide settings can create new problems for working devices.
Quick questions
Why does my laptop connect to Wi-Fi but not internet?
It can join the router but still fail DNS, IP, security or provider checks.
Is this different from weak Wi-Fi?
Yes. Weak Wi-Fi is a signal issue. Connected but no internet means the route beyond connection is failing.
Can you fix this remotely?
Sometimes, if the laptop can get online another way. Otherwise, a visit is usually better.
