If Windows 11 keeps disconnecting from WiFi, first determine whether the fault is the PC, the WiFi network, or the internet service. Restart the router and PC, run the Windows Network Troubleshooter, forget and reconnect to the network, and install pending Windows updates before changing adapter settings. If those steps fail, disable WiFi adapter power saving, update or roll back the wireless driver, and use Network Reset only as a last Windows-side repair.

## Is the disconnect happening on this PC, this WiFi network, or the internet itself?

Find the failure boundary before changing settings. That tells you whether to focus on Windows 11, the router and wireless signal, or your internet service.

When the problem occurs, check the WiFi icon in the taskbar.

```

Symptom

If Windows shows that the WiFi network is disconnected, the wireless link between the PC and router has failed. If it remains connected but Windows says there is no internet, the router may still be working while the internet connection, DNS, or the ISP is failing.

Use these checks:

- Connect a phone or another computer to the same WiFi network. If several devices lose access at the same time, the router, signal environment, or ISP is more likely responsible.
- Check the other device while the Windows 11 PC is having trouble. If other devices stay online, the problem is probably limited to the PC.
- Connect the Windows 11 computer to a different network, such as a phone hotspot. If it also disconnects there, suspect the PC’s driver, adapter, power setting, or wireless hardware.
- If the PC stays connected to another network but repeatedly fails on your home WiFi, compare the router’s settings, bands, signal strength, and firmware.

Write down whether the WiFi icon disappears or stays connected while websites fail, and when the symptom appears. A missing connection points to the wireless link. A connected icon with failed websites points to the router’s internet link, DNS, or the ISP. This distinction keeps you from resetting Windows for a router problem.

## Try these safe fixes before changing Windows settings

These steps apply to Windows 11 Home and Pro on laptops and desktops using a built-in or USB WiFi adapter. The first checks do not require Administrator access. Restarting the router and PC can briefly interrupt other users, but it does not erase settings. No backup is needed for these steps. Before changing anything, confirm that Airplane mode is off, WiFi is enabled, and the PC is within a reasonable range of the router.

1. Restart the router and the PC. Unplug the router’s power, wait until its lights have gone out, reconnect it, and wait for it to finish starting. Then restart Windows 11\. Do not use the router’s reset button; that can erase its configuration.
2. Move the PC closer to the router and test again. Thick walls, metal furniture, appliances, and distance can weaken the signal. If the connection becomes stable nearby, interference or poor signal strength is more likely than a Windows fault.
3. Run Windows’ built-in network troubleshooter.

```text
Settings > System > Troubleshoot > Other troubleshooters > Network and Internet > Run
```

Settings path

Follow the suggested repair and test the connection. The troubleshooter can identify a disabled adapter, incorrect network configuration, or a connection that has no internet access. If it reports that it could not identify the problem, continue rather than repeatedly running it. The expected result is a connection that stays online; if it still drops, continue to the next step.

1. Forget and reconnect to the WiFi network. This removes the saved profile for that network, so make sure you know the WiFi password first.

```text
Settings > Network & internet > Wi-Fi > Manage known networks > [your network] > Forget
```

Settings path

Select the network from the WiFi list, choose `Connect`, and enter the password again. Recreating the profile fixes damaged or outdated saved settings. If the network still drops, the saved profile was not the main cause.

1. Check for Windows updates.

```text
Settings > Windows Update > Check for updates
```

Settings path

Install available updates and restart if Windows requests it. Updates can include networking fixes, but a driver change can also introduce a new problem. If the disconnects began immediately after an update, use the driver rollback option in the next section instead of repeatedly reinstalling the same update. If the connection remains unstable after updating, continue with the adapter-specific fixes.

## Stop Windows 11 from putting the WiFi adapter to sleep

Windows can save power by turning off a wireless adapter, especially on a laptop. Disable that option first because it is reversible and does not remove your networks. You need Administrator permission to change the device’s power-management setting and install a driver.

1. Open Device Manager and locate the wireless adapter.

```text
Right-click Start > Device Manager > Network adapters > [your wireless adapter] > Properties
```

Settings path

1. Select the `Power Management` tab. Clear `Allow the computer to turn off this device to save power`, select `OK`, and restart Windows. If the tab is missing, leave this step alone; some adapters and drivers do not expose the setting. The expected result is that the adapter stays available after normal use and waking from sleep. If it still drops, continue.
2. Update the wireless driver from the `Driver` tab by selecting `Update Driver`. Prefer the driver supplied by your PC manufacturer or the wireless adapter manufacturer, matched to your exact Windows 11 model. Avoid generic driver-download sites and do not install a driver for a different adapter.
3. If the problem started after a driver or Windows update, open the same `Driver` tab and select `Roll Back Driver` when that button is available. Restart and test again. A rollback is appropriate only when a recent change matches the beginning of the problem; otherwise, use the current supported driver.
4. If the adapter has an `Advanced` tab, leave its values at their defaults unless you have a specific reason to change one. Settings such as preferred band, roaming aggressiveness, transmit power, or wireless mode vary by manufacturer. Changing several at once makes the cause harder to identify. A reasonable targeted test is to set `Preferred Band` to the band your router uses most reliably, if that option exists.

If the adapter disappears from Device Manager, shows a warning icon, or continues dropping on multiple networks after a correct driver install, suspect a failing adapter, USB connection, antenna, or motherboard rather than a saved Windows profile.

## Use Network Reset only after the targeted fixes fail

Network Reset is a broader repair, not a routine first step. It removes and reinstalls Windows network adapters and returns networking components to their default settings. It can remove saved WiFi networks and may require you to configure VPN software, virtual switches, virtualization adapters, or other network tools again.

Use Network Reset only after restarting, recreating the WiFi profile, checking updates, and addressing the adapter driver and power setting. Save any WiFi passwords and record VPN settings before proceeding.

Administrator permission is required, and Windows will restart the PC. Personal files are not removed.

```text
Settings > Network & internet > Advanced network settings > Network reset > Reset now
```

Settings path

Confirm the reset, allow Windows to restart, then select your WiFi network and enter its password. Reinstall or re-enable VPN and virtual-network software if it no longer works.

The expected result is a fresh Windows network configuration. If the connection still drops after Network Reset, repeating the reset is unlikely to help. Test the PC on another network and compare another device on the same router; those results point toward the router, interference, hardware, or ISP.

## How to confirm the connection is really fixed and what to do if it still drops

Test under the condition that originally caused the failure. If streaming triggered the drops, stream for at least the same type of session. If gaming or a work call exposed the problem, use that application rather than relying only on a quick web-page test. Watch both the WiFi status and internet access.

Where the router offers separate 2.4 GHz and 5 GHz network names, test each band from the same location. The 2.4 GHz band generally reaches farther and passes through obstacles better, while 5 GHz can offer higher performance at shorter range. If only one band is unstable, adjust the router’s band settings or position rather than changing unrelated Windows options.

A fix is credible when the PC remains connected during the original activity, reconnects normally after sleep or a restart, and other devices do not show a simultaneous outage. To observe the local WiFi link directly, open Command Prompt and run:

```cmd
ping 192.168.1.1
```

Command Prompt

Replace `192.168.1.1` with your router’s gateway address if it uses a different one. Continuous replies while websites fail suggest an internet, DNS, or ISP issue. Lost replies to the gateway point to WiFi signal, interference, the router, or the PC’s wireless link. The exact message varies by the cause, but the reply pattern is the useful comparison.

Persistent drops on every device, especially at the same time, indicate a router or ISP problem. Contact the ISP when the router’s internet or WAN connection fails while local WiFi remains available. Persistent drops only in one room suggest interference or weak coverage; move the router, remove nearby sources of interference, or test another band. Drops on one PC across multiple networks, despite a correct driver and power setting, point to a failing adapter, antenna, USB port, or other hardware. A USB WiFi adapter can help distinguish an internal adapter failure from a broader PC problem.

## Conclusion

If the PC remains stable during the activity that caused the drops, the fix worked. If Network Reset does not help, investigate the adapter or other hardware when the PC fails on multiple networks, and investigate the router, signal conditions, or ISP when several devices fail on the same WiFi.

## Frequently Asked Questions

### Why does my Windows 11 laptop disconnect from WiFi when it sleeps?

Windows may be turning off the wireless adapter to save power. In Device Manager, open the adapter’s Properties, select Power Management, clear \`Allow the computer to turn off this device to save power\`, and restart the PC. If the tab is missing, the adapter or driver does not expose that setting.

### Will Network Reset delete my files?

No. Network Reset does not delete personal files, but it removes and reinstalls network adapters, forgets saved WiFi networks, and may require VPN or virtual-network software to be configured again. Windows also restarts the PC.

### Why does WiFi say connected but there is no internet?

The wireless link to the router is still active, but the router may have lost its internet connection or Windows may be experiencing a DNS or configuration problem. Check another device on the same network before changing the PC. If several devices fail together, focus on the router or ISP; if only this PC fails, continue with the Windows checks.
