Windows 11 WiFi Keeps Disconnecting: Causes and Real Fixes

When Windows 11 WiFi keeps disconnecting, the connection usually drops for a few seconds, the network icon shows a globe or “No internet”, and then it reconnects, or it does not come back until you toggle Wi-Fi off and on. The cause can sit in three places: the router and your internet provider, the radio environment between the PC and the router, or the PC itself (its Wi-Fi driver, power settings or a damaged network profile). The steps below, for Windows 11 version 24H2 and 25H2 on Home and Pro, narrow it down in that order.

If you have no connection at all rather than one that keeps dropping, start with Windows 11 no internet instead.

First, find out where the problem is

What you notice	Points to
Phones and other PCs drop at the same time	Router, modem or internet provider
Only this PC drops, everywhere you take it	PC driver, power settings or adapter
Only this PC drops, only in one room	Signal strength, interference, band choice
Drops began after a Windows or driver update	Driver change; roll back or update
Drops after sleep or when on battery	Adapter power saving or driver
Drops when Bluetooth headphones are in use	2.4 GHz interference or shared Wi-Fi/Bluetooth chip

Quick checks: router, signal and Airplane mode

1. Restart the modem and router. Unplug both, wait at least 30 seconds, plug the modem back in first, wait for its lights to settle, then the router. Everyone on the network loses connection briefly while you do this.
2. Check Airplane mode. Go to Settings > Network & internet > Airplane mode and make sure it is off. Some laptops also have a wireless key or switch.
3. Move closer. Test with the PC in the same room as the router. If the drops stop, you have a range or interference problem, not a Windows one; a better router position or a mesh system is the fix.
4. Try the other band. If your router shows separate 2.4 GHz and 5 GHz (or 6 GHz) networks, connect to the other one. 2.4 GHz reaches further; 5 GHz and 6 GHz are faster but weaker through walls.
5. Turn off the VPN or third-party security software briefly to see if it is interrupting the connection.

Forget the network and reconnect

A damaged or outdated network profile can cause repeated drops, especially after a router change or password change.

1. Open Settings > Network & internet > Wi-Fi > Manage known networks.
2. Select your network and choose Forget.
3. Reconnect from the network icon on the taskbar and enter the password. If you need it, see find your Wi-Fi password on another PC that is still connected.

While you are in Wi-Fi settings, open the network’s properties and make sure Connect automatically when in range is on. If your router filters devices by hardware (MAC) address, check the Random hardware addresses option for that network: when it is on, the router sees a different address than the one it allows.

Run the Network and Internet troubleshooter

Microsoft’s first recommendation on Windows 11 is the automated troubleshooter in the Get Help app. Open Get Help from Start and search for the Network and Internet troubleshooter, or go to Settings > System > Troubleshoot > Other troubleshooters and select Run next to Network and Internet. It checks the adapter, IP settings and DNS, and fixes common problems automatically. Note anything it reports but cannot fix.

Stop the adapter from switching off to save power

Windows can power down the Wi-Fi adapter to save battery, and some drivers do not wake it reliably.

1. Right-click Start and select Device Manager.
2. Expand Network adapters and double-click your Wi-Fi adapter (its name usually includes Wi-Fi, Wireless or 802.11).
3. On the Power Management tab, clear Allow the computer to turn off this device to save power, then select OK.

On some laptops the Power Management tab is missing; that is normal and depends on the hardware. Also check Settings > System > Power & battery: if drops happen only on battery, try a less aggressive power mode while you test. Advanced driver settings such as roaming or preferred band appear on the Advanced tab of the same window, but their names and values differ from one adapter maker to another, so change them only if the PC or adapter maker documents what they do.

Update, roll back or reinstall the Wi-Fi driver

Driver problems are the most common cause when only one PC is affected.

• Update. Check Settings > Windows Update > Advanced options > Optional updates for a newer network driver, and the PC maker’s support page for your model. If you need internet to download it, use an Ethernet cable or download it on another device and copy it over.
• Roll back. If the drops started after a driver update, open the adapter in Device Manager, go to the Driver tab and select Roll Back Driver.
• Reinstall. In Device Manager, right-click the adapter and choose Uninstall device, then restart. Windows reinstalls a driver automatically. Microsoft suggests keeping a copy of the maker’s driver first in case Windows cannot find one.

If Bluetooth acts up at the same time, the same combined chip may be involved; see Windows 11 Bluetooth not working.

Reset the network stack and use Network reset

Microsoft documents these commands for repairing TCP/IP and DNS. Right-click Start, select Terminal (Admin) and run them one at a time:

netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

Restart the PC afterwards. If drops continue, use Network reset as the last software step: go to Settings > Network & internet > Advanced network settings > Network reset, select Reset now and confirm. It removes and reinstalls all network adapters and returns their settings to defaults, and the PC restarts. Afterwards you have to rejoin Wi-Fi networks, and you may need to reinstall VPN software or recreate virtual switches. Known networks may also come back set to the Public profile.

When to suspect hardware or the router

If the PC drops on several different networks even after a driver reinstall and Network reset, the adapter or its antennas may be faulty. Testing with a USB Wi-Fi adapter is a simple way to confirm it. If every device in the house drops, look at the router: check for a firmware update in its app or admin page, and ask your provider to check the line. As a final Windows step, Reset this PC rules out the software side completely.
