Windows 11 Wi-Fi Keeps Disconnecting: 9 Proven Fixes

Your Wi-Fi connection drops every few minutes on Windows 11. In our testing on multiple Windows 11 laptops, the culprit is almost always the power management setting that lets Windows shut off your Wi-Fi adapter to save battery. The fix takes under 60 seconds.

These 9 fixes are ranked from most likely to resolve your problem to the nuclear option. Start at the top and work down.

#Fix 1: Disable Wi-Fi Adapter Power Management

This is the fix that works for most people. Windows 11 puts your Wi-Fi adapter to sleep to save power. Sometimes it doesn’t wake back up properly, and the connection dies.

1. Right-click the Start button and select Device Manager
2. Expand Network Adapters
3. Right-click your wireless adapter (often labeled “Intel Wi-Fi” or similar) and choose Properties
4. Click the Power Management tab
5. Uncheck Allow the computer to turn off this device to save power
6. Click OK and restart your PC

We tested this on a Dell XPS 15 running Windows 11 23H2, where random disconnects had been happening every 15-20 minutes. After unchecking the power management option and restarting once, the disconnects stopped completely. We’ve since verified the same fix on a Lenovo ThinkPad and an Asus VivoBook with identical results.

A note on newer hardware: On Always-On/Always-Connected (AOAC) laptops, this tab doesn’t appear. Move on to Fix 2.

#Fix 2: Change Wireless Adapter Power Saving Mode

Fix 1 stops Windows from cutting power to the adapter entirely. This fix stops Windows from throttling it while it’s on.

1. Open Control Panel and go to Hardware and Sound > Power Options
2. Click Change plan settings next to your active power plan
3. Click Change advanced power settings
4. Scroll down and expand Wireless Adapter Settings
5. Expand Power Saving Mode and set it to Maximum Performance for both On Battery and Plugged In
6. Click Apply and OK

According to Microsoft’s network adapter power documentation, the default Balanced power plan switches your wireless adapter to Medium Power Saving mode when on battery. This activates 802.11 power save mode, which cuts battery life by 2-9% when disabled at Maximum Performance. On routers that don’t handle the 802.11 power save protocol cleanly, this is enough to cause random drops.

#Why Does Windows 11 Wi-Fi Keep Disconnecting?

Four causes account for the vast majority of cases.

Power management is responsible for most random drops on laptops. Windows silences the adapter to extend battery life, but some routers don’t recover the handshake correctly when the adapter wakes.

A bad driver update causes instant drops after a Windows Update. Roll it back.

Band congestion makes 5 GHz connections unreliable when you’re far from your router. 5 GHz has shorter range than 2.4 GHz and gets blocked by walls and floors. Switching to 2.4 GHz is free and takes 30 seconds.

Corrupted network configuration accumulates over time from failed connections, VPN installs, and major Windows Updates. A full network reset clears the slate.

#Fix 3: Roll Back or Update Your Wi-Fi Driver

If your Wi-Fi started dropping after a Windows Update, driver rollback is the fastest fix.

To roll back:

1. Open Device Manager and expand Network Adapters
2. Right-click your Wi-Fi adapter and choose Properties
3. Click the Driver tab
4. If Roll Back Driver is available, click it and follow the prompts

To update manually:

If rollback isn’t available, go to your laptop manufacturer’s website (Dell, HP, Lenovo, Asus, etc.) and download the latest Wi-Fi driver for your exact model. Install it, restart, and test.

In our testing on an HP Spectre running 24H2, a rolled-back Intel Wi-Fi 6 AX201 driver resolved disconnects that started immediately after a cumulative update. The Microsoft Learn community forum confirms that the Windows 11 24H2 update broke connectivity for multiple Intel adapter models.

#Fix 4: Flush DNS and Reset TCP/IP Stack

A corrupted DNS cache or TCP/IP stack can cause Windows 11 to lose its network configuration mid-session. This is a 2-minute command prompt fix.

1. Press Windows + S, type cmd, right-click Command Prompt, and choose Run as administrator
2. Run these commands one at a time, pressing Enter after each:

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

3. Restart your PC

This resets the Winsock catalog and IP stack without touching your saved Wi-Fi passwords. We use this regularly when testing VPNs and network tools. It consistently clears stale configuration that causes intermittent drops.

If you’re also seeing browser errors like “DNS_PROBE_FINISHED_NO_INTERNET” alongside the Wi-Fi drops, see our guide on fixing DNS probe errors for additional DNS troubleshooting steps.

#Fix 5: Switch Between 5 GHz and 2.4 GHz Bands

Modern routers broadcast two separate networks. If your Wi-Fi drops when you move around the house, band switching often fixes it.

5 GHz is faster but shorter in range. Walls and distance weaken it significantly.

2.4 GHz is slower but covers more distance and passes through walls better.

To switch: open your Wi-Fi settings and look for two network names from your router, typically one ending in “5G” or “5GHz.” Connect to the other band and test for 15-20 minutes.

If both bands drop, the problem is in your adapter or Windows settings, not the frequency.

#Fix 6: Restart the WLAN AutoConfig Service

WLAN AutoConfig manages all Windows 11 wireless connections. If it crashes, your Wi-Fi goes with it.

1. Press Windows + R, type services.msc, and press Enter
2. Scroll down to WLAN AutoConfig
3. Right-click it and choose Restart
4. Double-click it and confirm Startup type is set to Automatic

This takes about 30 seconds and requires no restart. It’s especially effective for drops that follow a pattern, like disconnecting every time your PC wakes from sleep or after being idle for several minutes.

#Fix 7: Update Your Router’s Firmware

Router firmware bugs can cause specific Windows 11 clients to drop repeatedly while other devices stay connected. Only your Windows 11 PC dropping while your phone is fine points to the router.

Log in at 192.168.1.1 or 192.168.0.1. Look under Administration or Advanced for firmware updates.

Asus, Netgear, and TP-Link routers have had documented stability problems with Windows 11 clients that firmware updates fixed. Check your manufacturer’s support page for the latest version.

#Is Your Router the Problem?

If your Windows 11 PC drops while all other devices stay connected, the issue is specific to the Windows-router interaction. Quick diagnostic tests:

• Connect your Windows 11 PC to a mobile hotspot. If it stays connected for 30 minutes, the problem is with your router, not Windows itself
• Check if other Windows PCs on the same network also drop. If they do, it’s definitely the router
• Reboot your router and modem by unplugging them for 30 seconds

Microsoft’s Wi-Fi troubleshooting guide lists router reboot as step two.

#Fix 8: Change Your DNS Servers

Your ISP’s default DNS servers can be unreliable. Switching to a public DNS reduces connection drops caused by DNS lookup failures.

1. Press Windows + I to open Settings
2. Go to Network and Internet > Wi-Fi
3. Click your connected network, then click Edit next to DNS server assignment
4. Switch to Manual
5. Enter 8.8.8.8 for the primary DNS and 8.8.4.4 for the secondary (Google DNS)
6. Alternatively, use Cloudflare: 1.1.1.1 and 1.0.0.1
7. Click Save

Most effective when sites load slow right before a drop, or drops worsen at peak hours.

#Fix 9: Run Network Reset (Last Resort)

Network reset removes all adapter settings, uninstalls your network adapters, and reinstalls them fresh. It fixes problems nothing else touches.

1. Press Windows + I to open Settings
2. Go to Network and Internet > Advanced network settings
3. Click Network reset
4. Click Reset now and confirm

Your PC restarts and takes a few minutes to reinstall network adapters. Microsoft’s Wi-Fi troubleshooting page states that network reset is particularly effective for connection problems that started after upgrading from Windows 10 to Windows 11.

What you’ll lose: VPN configs, Hyper-V virtual switch settings, and custom DNS entries. Write down your Wi-Fi passwords first.

After network reset, reconnect to your Wi-Fi and reinstall any VPN software. If disconnects persist after network reset, the issue is hardware-level. An external USB Wi-Fi adapter is a quick way to confirm whether your built-in adapter is failing.

#Bottom Line

Start with Fix 1. Disabling the power management setting in Device Manager resolves Wi-Fi disconnects for most Windows 11 laptops.

If drops started right after a Windows Update, skip straight to Fix 3 and roll back your driver. For everything else, work through the list in order. Network reset (Fix 9) clears nearly every software-level issue, so try it before buying replacement hardware. If disconnects persist after Fix 9, the built-in adapter is likely failing.

If you’re not sure your PC meets Windows 11 requirements, our Windows 11 compatibility check guide walks through the hardware requirements. You can also check whether authenticating to Wi-Fi is causing a separate error if your PC connects but then immediately drops with an error message.
