If Wi-Fi is connected but there is no internet, first check another device on the same network and try more than one website. Those two comparisons help you decide whether to focus on one device, the home network or a single online service.
Do the checks below in order. After each change, test the connection again. You do not need to change every setting, download a driver utility or factory-reset your router to begin troubleshooting.
Find out what is failing
A device can reach a wireless router while the router has trouble reaching the internet. An app can also fail even when other internet activity works. Rather than treating every connection problem the same way, collect one useful clue at a time.
| What you find | Where to focus first |
|---|---|
| One website fails; others load | The website, app or browser session |
| One device fails; another works on the same Wi-Fi | The affected device and its connection |
| Several devices fail on the same Wi-Fi | The router, modem or internet provider |
| The device works on another trusted network | The original network or its settings |
These are starting points, not a diagnosis. For example, a phone may appear to work because it switched to cellular data. Check which connection it is using before treating it as evidence that the Wi-Fi is fine.
Check the basics on the affected device
- Confirm that Wi-Fi is on and airplane mode is off.
- Check the network name. A neighbor’s or guest network may look similar.
- Move closer to the router and try again.
- Save open work, then restart the device.
On a hotel, library or other guest network, check for the operator’s sign-in instructions. Use the official network information rather than an unexpected message asking for payment or account details.
If one site is the only problem, try a separate website before changing network settings. Note any error message exactly. “This page is taking too long” and “your account cannot sign in” describe different problems, even if both stop you from getting work done.
Use Windows 11’s built-in network help
Microsoft’s current Windows Wi-Fi guide recommends the Network and Internet troubleshooter in the Get Help app for Windows 11. Follow the prompts and record any reported result.
Keep the device’s Windows version in mind when following instructions. A menu shown for a different version may not match your screen. If this is a work or school computer, follow the organization’s support process before changing managed settings.
Describe the outcome in plain language: “the troubleshooter found no issue” or “it reported a problem with the adapter.” That is more useful than repeating the same repair several times without recording what happened.
If multiple devices fail, check the network equipment
Look at the modem or router’s indicator lights and compare them with the manufacturer’s or internet provider’s instructions. Light colors and meanings vary, so use the guide for the equipment you actually have.
If you can access your provider’s official outage page using another connection, check it. A provider outage needs a different response from a problem limited to your laptop.
When a restart is appropriate, follow the provider’s instructions for the equipment and allow it to reconnect. Tell anyone using the network first; a restart can interrupt a call or an upload. Do not keep cycling the power while the device is starting up.
A restart is different from a factory reset. Do not press a recessed reset button as a routine troubleshooting step. Resetting equipment can remove settings you will need to restore. On a shared-building or managed network, ask the administrator rather than changing its equipment.
If only one device fails, keep the next steps targeted
Note whether the problem started after an update, a new adapter or a change of location. Try a trusted alternative network if one is available and you are authorized to use it. Write down whether the problem follows the device.
Intel’s wireless troubleshooting guidance points to drivers, configuration and interference as possible contributors. It also notes that computer manufacturers may customize drivers. Use the device manufacturer’s official support channel when a driver check is needed.
Avoid installing utilities from an unfamiliar ad simply because they promise to fix every connection problem. If you are considering new equipment, use our online shopping checklist to verify compatibility before buying a replacement.
Know when to stop making changes
Randomly changing DNS, proxy, VPN, firewall and adapter settings together makes the original problem harder to identify. Keep a record and change only what you understand. Ask the administrator to investigate protection or VPN software on a managed device.
Microsoft includes network reset among its later troubleshooting options. Read its consequences before using it, and make sure you have what you need to reconnect. It is not the first step for an unexplained connection failure.
Give support a useful problem report
Copy this short format into your notes:
- Device and system: laptop model and Windows version.
- Problem: the exact error and when it began.
- Comparison: whether another device works on this network.
- Checks tried: each action and its result.
- Pattern: whether it happens on other trusted networks too.

Common Wi-Fi questions
Should I buy a new router immediately?
First establish whether several devices fail, check the provider’s outage information and follow the equipment’s troubleshooting instructions. One laptop failing does not, by itself, show that the router needs replacing.
Why does Wi-Fi work on my phone but not my laptop?
Check that the phone is really using Wi-Fi rather than cellular data. If it is, focus the next checks on the laptop and how it connects to that network.
