Windows 11 WiFi Keeps Disconnecting How to Fix

If your Windows 11 WiFi keeps dropping every few minutes, the cause is almost always one of three things: an aggressive power-saving setting, an outdated or buggy network driver, or interference on the wireless band. This guide walks through the fixes that resolve the vast majority of disconnection problems, starting with the quickest wins.

Stop Windows From Powering Down Your WiFi Adapter

By default, Windows 11 is allowed to switch off your wireless adapter to save energy. On laptops this is the single most common reason for random drops, especially after the machine has been idle.

1. Open Device Manager (right-click the Start button and select it).
2. Expand Network adapters, right-click your WiFi adapter, and choose Properties.
3. Go to the Power Management tab and uncheck Allow the computer to turn off this device to save power.
4. Click OK.

Next, stop the power plan from throttling the adapter. Go to Settings > System > Power & battery, or open the classic panel via Control Panel > Power Options > Change plan settings > Change advanced power settings. Expand Wireless Adapter Settings > Power Saving Mode and set it to Maximum Performance for both battery and plugged-in states.

Update or Reinstall the Network Driver

A flaky driver causes intermittent drops that no setting will fix. Always prefer the driver from your laptop or motherboard manufacturer (Dell, HP, Lenovo, ASUS) or the chipset vendor (Intel, Realtek, Qualcomm) over the generic one Windows installs.

Clean reinstall

1. In Device Manager, right-click your WiFi adapter and choose Uninstall device. Tick Attempt to remove the driver if offered.
2. Restart the PC. Windows will reinstall a baseline driver automatically.
3. Install the latest driver downloaded from the manufacturer’s support page.

If a recent update caused the problem, do the opposite: open the driver’s Properties > Driver tab and click Roll Back Driver.

Reset the Network Stack

Corrupted TCP/IP or Winsock settings produce disconnects that survive driver changes. A full network reset clears them. First try the targeted commands in an elevated Command Prompt (right-click Start > Terminal (Admin)):

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

Reboot afterward. If problems persist, go to Settings > Network & internet > Advanced network settings > Network reset and click Reset now. This removes and reinstalls every adapter, so you will need to re-enter your WiFi password.

Fix Interference and Router-Side Issues

If only some devices drop, or drops happen at specific times of day, the problem is the connection itself rather than Windows.

• Switch bands: The 2.4 GHz band reaches farther but is congested. The 5 GHz band is faster and cleaner at short range. In your router settings, give the two bands different network names so you can pick the best one.
• Change the channel: In a crowded building, set the 2.4 GHz radio to channel 1, 6, or 11 to avoid overlap.
• Forget and rejoin: Go to Settings > Network & internet > Wi-Fi > Manage known networks, click Forget on your network, then reconnect.
• Update router firmware and reboot the router. Old firmware is a frequent cause of nightly drops.

Finally, check for WiFi 6E / random hardware addresses conflicts. Some routers handle the privacy feature poorly. Under Settings > Network & internet > Wi-Fi > (your network) > Random hardware addresses, try turning it Off for that network.

Frequently Asked Questions

Why does my Windows 11 WiFi only disconnect when the laptop is idle?

This is almost always the power-management setting on the adapter. Uncheck Allow the computer to turn off this device to save power in Device Manager and set the Wireless Adapter Power Saving Mode to Maximum Performance in your power plan.

Does resetting the network delete my saved WiFi passwords?

Yes. The full Network reset under Advanced network settings removes all saved networks, so you will need to re-enter passwords. The smaller netsh commands do not delete saved networks.

Should I use 2.4 GHz or 5 GHz to stop disconnects?

Use 5 GHz when you are close to the router for speed and less interference. Use 2.4 GHz when you are far away or behind walls, since it has better range. Switching bands often resolves drops caused by congestion.

How do I know if the problem is my PC or my router?

If other devices on the same network stay connected while only your PC drops, focus on the Windows driver and power settings. If every device drops at once, the router or internet line is the cause.
