Wi-Fi Keeps Disconnecting on Windows 11? Fix It

If your Windows 11 PC drops Wi-Fi every few minutes, you’re not alone. This guide walks you through the most effective fixes, from simple power management tweaks to resetting network settings, so you can get a stable connection again.

What You’ll Need

Administrator access to your Windows 11 PC
Your Wi-Fi router’s admin password (for a router reset step)
About 15–20 minutes of patience

Step-by-Step

Run the built-in network troubleshooter. Open Settings (Win + I) > System > Troubleshoot > Other troubleshooters. Click Run next to “Network and Internet.” Follow the prompts; Windows will often detect and fix common issues like a misconfigured adapter or a weak signal.
Restart your router and PC. Unplug your router and modem for 30 seconds, then plug them back in. While they reboot, restart your PC. This clears temporary glitches on both ends.
Change the Wi-Fi power saving mode. Open Device Manager (right-click the Start button). Expand Network adapters, right-click your Wi-Fi adapter (usually has “Wireless” or “Wi-Fi” in the name), and select Properties. Go to the Power Management tab and uncheck “Allow the computer to turn off this device to save power.” Click OK. This is the most common fix for random disconnects.
Update or reinstall the Wi-Fi driver. In Device Manager, right-click your Wi-Fi adapter and choose Update driver > Search automatically for drivers. If that doesn’t help, go to your PC manufacturer’s website (Dell, HP, Lenovo, etc.) and download the latest driver for your exact model. If the issue persists, right-click the adapter and select Uninstall device (check “Delete the driver software for this device”), then restart – Windows will reinstall the driver automatically.
Adjust the wireless adapter’s roaming aggressiveness. In Device Manager, right-click your Wi-Fi adapter > Properties > Advanced tab. Find “Roaming Aggressiveness” and set it to Highest or High. Also look for “Power Output” or “Transmit Power” and set it to Highest. Click OK.
Disable Wi-Fi Sense and hotspot features. Go to Settings > Network & internet > Wi-Fi. Turn off “Random hardware addresses” (if on). Also, go to Settings > Network & internet > Mobile hotspot and ensure it’s off.
Run a few Command Prompt commands. Right-click the Start button and select Terminal (Admin) or Command Prompt (Admin). Type these one at a time, pressing Enter after each:
- netsh wlan show wlanreport – this generates a report (you can view it later).
- netsh int ip reset – resets the IP configuration.
- netsh winsock reset – resets the network socket catalog.
- ipconfig /release then ipconfig /renew – refreshes your IP address.
Restart your PC after these commands.
Set your Wi-Fi to a fixed channel (advanced). Log into your router’s admin page (usually at 192.168.1.1 or 192.168.0.1 – check the sticker on the router). Find the wireless settings and manually set the channel to 1, 6, or 11 (for 2.4 GHz) or a specific channel like 36 or 149 (for 5 GHz). Save and reboot the router. This avoids interference from neighbors’ networks.
Reset the network stack completely. In the same admin terminal, type netsh int reset all and press Enter. Then go to Settings > Network & internet > Advanced network settings > Network reset. Click Reset now and confirm. This will remove all Wi-Fi profiles and VPN adapters – you’ll need to reconnect to your Wi-Fi and re-enter the password.
Check for Windows updates. Go to Settings > Windows Update and click Check for updates. Install any pending updates, especially driver and security updates, then restart.

Common Mistakes

Skipping the router restart. Many people only restart the PC, but the router often holds the issue. Always restart both.
Disabling power saving on the wrong adapter. Make sure you change the power setting on the Wi-Fi adapter, not the Ethernet adapter (if you have one).
Using a VPN or proxy that interferes. VPN software can cause disconnects. Temporarily disable it to test.
Ignoring physical obstructions. Walls, metal objects, and even microwaves can disrupt Wi-Fi. Move closer to the router to test.

Tips

Prefer 5 GHz over 2.4 GHz if you’re near the router – it’s faster and less congested, though shorter range.
Keep your Wi-Fi driver updated – set Windows Update to automatically install driver updates.
Use a wired connection for critical work – if Wi-Fi keeps failing, an Ethernet cable is the most stable fallback.
Change your Wi-Fi password if you suspect someone else is using your network and slowing it down.

Troubleshooting

If the steps above don’t solve it:

Check if the issue is only on one device. If other devices stay connected, the problem is likely your PC’s Wi-Fi adapter. Try using a USB Wi-Fi dongle to test.
Update your router’s firmware. Log into the router admin page and look for a “Firmware Update” option. An outdated router can cause random drops.
Try a different Wi-Fi band. If you’re on 5 GHz, switch to 2.4 GHz (or vice versa) in the router settings. Some adapters have issues with one band.
Check the Event Viewer for errors. Open Event Viewer (search in Start) and look under Windows Logs > System for warnings from “WLAN-AutoConfig” or “Netwtw” – these can hint at the cause.
Consider a hardware issue. If the Wi-Fi adapter is failing, you may need to replace it (for laptops, a USB adapter is an easy fix).

Frequently Asked Questions

Why does my Wi-Fi keep disconnecting but shows full signal?

A strong signal doesn’t guarantee a stable connection. Interference, outdated drivers, or power-saving settings can cause drops even with full bars.

Will resetting Windows fix the Wi-Fi issue?

A network reset (step 9) often works, but a full Windows reset (reinstall) is a last resort – try all other steps first.

How do I know if my driver is outdated?

In Device Manager, right-click the Wi-Fi adapter > Properties > Driver tab. The “Driver Date” and “Driver Version” can be compared with the latest on your manufacturer’s site.

Can a VPN cause Wi-Fi disconnects?

Yes, VPN software can interfere with network adapters. Disable the VPN and test for a few hours to see if disconnects stop.

Is there a way to prevent Windows from turning off the Wi-Fi adapter automatically?

Yes, as shown in step 3, uncheck “Allow the computer to turn off this device to save power” in the adapter’s Power Management tab.

Why does my Wi-Fi drop only when I play games or stream?

High bandwidth usage can expose a weak router or adapter. Try QoS settings on your router to prioritize your device, or move closer to the router.

General steps for current mainstream versions; menus can differ by device and version. See the disclaimer or report an error.
