Windows 11 24H2 Wi-Fi Keeps Disconnecting: Fixes That Work in 2026
Windows 11 24H2 Wi-Fi keeps disconnecting for many users after the update, especially after sleep, during video calls, or when the laptop switches power states. The mistake is blaming the router first, when the real cause is often a driver change, Wi-Fi power saving, or a broken network profile after the upgrade.
This guide shows the safest fix order, starting with quick checks and reversible settings before moving to deeper resets. You will learn how to test whether the problem is Windows, the Wi-Fi adapter, or the router so you do not waste time changing the wrong thing.
Quick answer: In most cases, Windows 11 24H2 Wi-Fi disconnects are caused by driver issues, adapter power settings, or stale network configuration after the update. Start by testing Ethernet, checking the Wi-Fi driver, disabling Wi-Fi power saving, and only use Network reset later if simpler steps do not fix the problem.
Windows 11 24H2 Wi-Fi Keeps Disconnecting: Start Here
First, note when disconnects occur: on battery, after sleep, during video calls, or while downloading. This helps confirm whether the problem is more likely related to power settings, roaming, or the network itself.
Also test Ethernet for 10–20 minutes. If wired is stable but Wi-Fi keeps dropping, focus on the Wi-Fi driver, adapter settings, and channel interference rather than your ISP.
If you see “No internet, secured” or “Connected but no internet,” test a different device on the same Wi-Fi. If other devices work, the problem is likely on this PC.
Update or Roll Back Drivers Safely
Open Device Manager > Network adapters > your Wi-Fi adapter > Properties > Driver. Try Update driver first.
If the issue started right after a driver or Windows update, use Roll Back Driver to return to the previous version.
If Windows Update does not help, install the correct driver package from your laptop maker or adapter vendor. Restart the PC after changing the driver.
Optimise Wi-Fi Driver Power Management and Adapter Settings
In Device Manager > your Wi-Fi adapter > Power Management, uncheck Allow the computer to turn off this device to save power. This is a common reason Wi-Fi keeps dropping on laptops.
Then go to Settings > System > Power & battery and test Balanced or Best performance, depending on what your PC shows.
In the adapter’s Advanced tab, adjust settings carefully:
- Reduce roaming aggressiveness if your Wi-Fi keeps switching between access points.
- Try disabling automatic band switching if 5 GHz is unstable.
- If reconnect loops started after a router security change, test a compatible WPA2/WPA3 setting on the router and reconnect.
Reset Network Settings (24H2) and Clear Old Wi-Fi Profiles
Go to Settings > Network & internet > Advanced network settings > Network reset. Use this later in the process, because it removes installed network adapters and resets their settings to defaults after restart.
Before a full reset, try these commands in Windows Terminal (Admin):
netsh winsock reset
netsh int ip reset
Restart the PC after running them.
Also forget and re-add your Wi-Fi network. This can clear a corrupted profile that causes repeated reconnects or “connected but no internet” behaviour.
Fix Router and Channel Issues (2.4 GHz vs 5 GHz)
Router settings can expose weak spots after a Windows upgrade, especially in busy flats and neighbourhoods.
If other devices in your home also drop randomly, the issue may be wider than this PC. See how to stop smart home devices disconnecting on Wi-Fi and improve stability across multiple devices.
If you are not sure which band to use, start with 2.4 GHz vs 5 GHz Wi-Fi: which one is more stable.
If your PC only drops on 2.4 GHz, use Fix slow 2.4 GHz Wi-Fi at home (2026) to check interference and crowded channels.
Set channels manually to reduce interference:
- 2.4 GHz: channel 1, 6, or 11
- 5 GHz: try a clean non-DFS channel if DFS events cause drops
For safe channel choices, follow Best Wi-Fi channel settings for 2.4 GHz and 5 GHz (2026).
If you use mesh, weak node placement can trigger roaming that looks like a disconnect. Use Set up mesh Wi-Fi for smart home to improve placement and backhaul.
If your coverage is still weak, compare the best mesh Wi-Fi systems for smart homes.
Check VPNs, Security Software, and Wi-Fi Services
Temporarily disable VPN clients and third-party firewalls to confirm they are not interfering. Some VPN filters and virtual adapters can break local networking after updates.
In Services, confirm WLAN AutoConfig is running.
Avoid running vendor Wi-Fi utilities and Windows Wi-Fi management at the same time. Pick one, or you may see profile conflicts and repeated reconnect loops.
Fix Sleep, Hibernate, and Fast Startup Disconnects
If Wi-Fi drops after sleep or after startup, begin with power settings.
In Control Panel > Hardware and Sound > Power Options > your plan > Change plan settings > Change advanced power settings > Wireless Adapter Settings, set Power Saving Mode to Maximum Performance for testing.
You can also test with Fast Startup turned off: Control Panel > Power Options > Choose what the power buttons do > Change settings that are currently unavailable > Turn on fast startup (unchecked).
If sleep-related drops continue, update BIOS/UEFI and chipset drivers from the PC manufacturer. These updates can improve power handling and device resume behaviour.
Troubleshooting Steps for a 169 IP Address (No Internet)
If your PC shows a 169.254.x.x IP address, it usually means Windows could not get an IP address from DHCP and assigned itself an Automatic Private IP Addressing address instead.
Try this order:
- Restart the router and the PC.
- Forget the network and reconnect.
- Disable and re-enable the Wi-Fi adapter.
- Run the reset commands shown earlier.
- Test with a phone hotspot to confirm whether the router DHCP service is the cause.
If hotspot works but your router does not, focus on router DHCP settings, firmware, or interference.
Advanced Diagnostics and Logs
Use Event Viewer > Windows Logs > System and filter for WLAN, Network, and DHCP events. Repeated authentication or DHCP errors can point to security mode issues, DHCP failure, or driver problems.
Run PowerShell:
Get-NetAdapter | Format-Table Name, Status, DriverInformation
Generate a Wi-Fi report:
netsh wlan show wlanreport
This report can help you match disconnect times against sleep, roaming, authentication, or router events.
Check the PC maker or Wi-Fi adapter vendor site for the latest drivers and updates.
When to Consider Hardware or Firmware Updates
Update router firmware from the manufacturer.
If your router is older or struggles with multiple devices, upgrading hardware can fix random drops completely. Compare the best Wi-Fi 6 routers for multiple smart devices for better stability and performance.
If your adapter is old, a modern Wi-Fi 6 or Wi-Fi 6E USB adapter is a clean test. Choose one from a brand that clearly lists Windows 11 support and updated drivers.
Common Mistakes
- Ignoring router firmware updates after the Windows 11 upgrade.
- Leaving Allow the computer to turn off this device enabled for the Wi-Fi adapter.
- Using Network reset too early instead of trying simpler checks first.
- Mixing vendor Wi-Fi utilities with Windows management at the same time.
- Using crowded automatic channels without checking interference.
- Assuming ISP issues when only Wi-Fi drops and Ethernet stays stable.
How to Choose the Right Fix Order
Start with reversible steps: forget and re-add the network, disable Wi-Fi power saving, and test stability.
If stability improves, refine router channels and band settings next.
If drops continue, focus on drivers: update or roll back using vendor packages. Only then use Network reset and deeper sleep or Fast Startup changes.
When software steps fail, update router firmware or test with a known-good external Wi-Fi adapter to isolate hardware limits.
If you are still unsure whether the problem is your PC, router, or overall coverage, this router vs mesh comparison can help you choose the right upgrade path.
FAQs
Q: Why Does Windows 11 Wi-Fi Keep Disconnecting After the 24H2 Upgrade?
A: Common causes include a changed or unstable driver, Wi-Fi power saving, stale network configuration, or router-side interference. Start with the adapter driver and power settings first.
Q: Should I Reinstall the Wi-Fi Driver to Resolve Constant Wi-Fi Disconnects?
A: Yes, if update and rollback do not help. Uninstalling the network adapter driver and restarting can make Windows reinstall the driver automatically, but it is smart to have the correct driver package ready from the PC maker first.
Q: How Do I Fix “No Internet, Secured” on Windows 11 When the Wi-Fi Connection Looks Fine?
A: This usually means the PC is connected to the local Wi-Fi network but cannot reach the Internet. Check IP renewal, DNS, proxy settings, and whether the address has fallen into the 169.254.x.x range, which usually points to DHCP failure.
Q: I Upgraded From 23H2. Is That Why My Wi-Fi Connection Is Unstable Now?
A: It can be. A feature update can change driver behaviour, power handling, or saved network settings, which may trigger unstable Wi-Fi until the adapter and network configuration are corrected.
Q: Do Intel Wi-Fi Cards Need Intel Drivers, and How Do I Find the Right One?
A: You should use the correct driver for your exact hardware and Windows version. Match the adapter name in Device Manager with the right driver from your laptop maker or the adapter vendor.
Q: Why Is 5 GHz Wi-Fi Unstable on My Dell Latitude but 2.4 GHz Works?
A: Possible causes include band filtering in the adapter driver, router channel issues, weak signal, or roaming behaviour. Check the adapter’s advanced settings, test a different 5 GHz channel, and confirm the signal is strong enough.
Q: Can My Wi-Fi Password or Encryption Policy Cause Repeated Disconnects?
A: Yes. Authentication problems, router security settings, and profile mismatches can all trigger reconnect loops.
