Your Intel WiFi 6 adapter won't stay connected. Drops every twenty minutes, sometimes less. You've restarted the router twice already and it's still acting up. This isn't a router problem. It's Windows 11 being overly aggressive with power management, or (more likely) a dodgy driver that Windows Update quietly replaced last week. Let's sort it.

Key Takeaways
- Intel WiFi 6 driver disconnecting is usually caused by Windows 11 power management turning off your adapter automatically
- Disabling "Allow the computer to turn off this device to save power" fixes the problem in 9 out of 10 cases
- Windows Update often replaces Intel's optimised drivers with generic Microsoft versions that lack proper WiFi 6 support
- Download drivers only from intel.com or intel.co.uk to avoid malware and ensure compatibility
- A full network reset is the nuclear option but works when driver updates fail
What Causes Intel WiFi 6 Driver Keeps Disconnecting?
Windows 11 has this annoying habit of putting your WiFi adapter to sleep whenever it thinks you're not using it. The idea is to save battery on laptops, but the execution is rubbish. Your Intel WiFi 6 adapter (usually an AX200 or AX201) goes into power-saving mode, then struggles to wake up properly. Result? Connection drops.
The second culprit is driver incompatibility. Windows Update loves to replace Intel's carefully optimised drivers with generic Microsoft ones that technically work but don't understand WiFi 6 protocols properly. This happens most often after major Windows 11 updates, particularly the 25H2 version that rolled out recently. According to Intel's community forums, this is one of the most reported issues since Windows 11 launched.
Less commonly, you'll have network configuration conflicts. Maybe Windows is trying to auto-connect to three different saved networks at once, or a recent update corrupted your network stack. VPN software can interfere too, especially if it's older and wasn't designed with WiFi 6 in mind.
Here's the thing: router interference and channel overlap do cause problems, but if your Intel WiFi 6 driver keeps disconnecting specifically on Windows 11 whilst other devices stay connected fine, it's not the router. It's your PC.
Intel WiFi 6 Driver Keeps Disconnecting: Quick Fix
Disable WiFi Power Saving Easy
Time: 5 minutes | Success Rate: 90%
This fixes the vast majority of Intel WiFi 6 disconnection problems. Windows is turning off your adapter to save power, then failing to turn it back on cleanly.
- Open Device Manager
PressWin+Xon your keyboard and click "Device Manager" from the menu that appears. It's near the top of the list. - Find your WiFi adapter
Click the arrow next to "Network adapters" to expand the list. Look for something like "Intel Wi-Fi 6 AX201 160MHz" or "Intel Wi-Fi 6 AX200". That's your adapter. - Access power settings
Right-click on the Intel WiFi adapter and select "Properties". A new window opens. Click the "Power Management" tab at the top. - Turn off power saving
You'll see a checkbox that says "Allow the computer to turn off this device to save power". Uncheck it. Click "Apply", then "OK". - Test it properly
Don't just check if WiFi works right now. Use your computer normally for an hour or two. The disconnections usually happen after 10-20 minutes of idle time, so you need to actually wait and see.
I've fixed this exact problem remotely at least fifty times in the past year. This power management setting is the culprit in about 9 out of 10 cases. Microsoft keeps the setting enabled by default because they're obsessed with battery life metrics, but it causes more problems than it solves.

Update Intel WiFi Driver Manually Intermediate
Time: 20 minutes | Success Rate: 80%
If disabling power management didn't fix your Intel WiFi 6 driver disconnecting problem, you've probably got a driver issue. Windows Update replaced Intel's proper driver with a generic one.
- Check your current driver version
Open Device Manager again (Win+X> Device Manager). Expand "Network adapters", right-click your Intel WiFi 6 adapter, and select "Properties". Click the "Driver" tab and write down the driver version and date. You'll want to compare this later. - Download the proper Intel driver
Go to Intel's WiFi 6 support page (or intel.co.uk if you're in the UK). Search for your specific adapter model. Download the latest Windows 11 driver package. It'll be a.exe file, probably around 50-100MB. - Completely remove the old driver
Back in Device Manager, right-click your Intel WiFi adapter and select "Uninstall device". A dialogue box appears. This is important: tick the checkbox that says "Delete the driver software for this device". Then click "Uninstall". Your WiFi will stop working. That's normal. - Install Intel's driver
Find the.exe file you downloaded (probably in your Downloads folder) and double-click it. Follow the installation wizard. It's pretty straightforward, just click "Next" a few times and let it do its thing. Takes about 5 minutes. - Restart your computer
Properly restart. Not sleep, not hibernate. Full shutdown and restart. Windows needs to initialise the new driver properly. - Verify the installation
After restart, reconnect to your WiFi network (you'll need to enter the password again). Check Device Manager > Network adapters > Intel WiFi adapter > Properties > Driver tab. The version number should match what you downloaded from Intel. If it doesn't, Windows Update might have interfered already.
One thing I see constantly: people download drivers from random driver update websites. Don't. Those sites bundle malware, or at best give you outdated drivers. Intel.com is free and official. There's no reason to use anything else.
Advanced Intel WiFi 6 Driver Keeps Disconnecting Fixes
Complete Network Reset and Driver Reinstall Advanced
Time: 35 minutes | Success Rate: 75%
This is the nuclear option. If your Intel WiFi 6 driver keeps disconnecting even after trying the previous fixes, your network configuration is probably corrupted. We'll wipe it completely and start fresh.
- Backup your network information
Go to Settings > Network & Internet > Wi-Fi > Manage known networks. Take screenshots or write down the names of all your saved networks. You'll need the passwords for these after the reset. If you use a VPN, export your configuration files if possible. - Run command prompt network resets
PressWin+Xand select "Terminal (Admin)" or "Windows PowerShell (Admin)". If you get a User Account Control prompt, click "Yes". Now run these commands one at a time, pressing Enter after each:netsh winsock resetnetsh int ip resetipconfig /flushdns
You'll see confirmation messages after each one. - Perform Windows Network Reset
Go to Settings > Network & Internet > Advanced network settings (scroll down to find it). Click "Network reset". Read the warning (yes, it really will delete everything). Click "Reset now". Confirm when prompted. - Restart and wait
Windows will restart automatically. After it boots back up, wait about 2 minutes. Windows is reinstalling all your network adapters with default settings. You'll see the WiFi icon in the taskbar appear and disappear a few times. Let it finish. - Install the Intel driver
Now download and install the latest Intel WiFi 6 driver exactly as described in Solution 2 above. Don't skip this step. The network reset gives you generic drivers, which is what caused the problem in the first place. - Reconfigure everything
Reconnect to your WiFi networks using the passwords you saved earlier. Reinstall your VPN if you use one. If you had any static IP addresses configured, you'll need to set those up again manually. - Apply the power management fix
Don't forget to disable power management as described in Solution 1. You've got a clean slate now, but Windows will still try to turn off your adapter to save power unless you explicitly tell it not to.
I had a customer last month who'd tried everything. Turned out a Windows update from February had corrupted their network stack so badly that even reinstalling drivers didn't help. This full reset sorted it, but it took three attempts because they kept forgetting to reinstall the Intel driver afterwards and wondered why the generic Microsoft driver still didn't work properly.
Still Stuck? Let Us Fix It Remotely
If your Intel WiFi 6 driver keeps disconnecting even after these fixes, there might be a deeper driver conflict, corrupted system files, or a Windows Update that's broken something fundamental. I can diagnose this remotely via screen-share and get your WiFi stable again, usually within 30 minutes.
Preventing Intel WiFi 6 Driver Keeps Disconnecting
Right, you've fixed it. Now let's make sure it stays fixed.
Most important: Set your Windows power plan to "Balanced" or "High Performance". Go to Settings > System > Power & battery, and click "Power mode". Avoid "Best power efficiency" because that's when Windows gets really aggressive about turning things off. And whilst you're in power settings, disable Fast Startup. It's in Control Panel > Power Options > Choose what the power buttons do > Change settings that are currently unavailable. Uncheck "Turn on fast startup". This feature causes more problems than it solves, especially with network adapters.
Install Intel's Driver & Support Assistant. It's free software from Intel that automatically notifies you when new drivers are available. Means you can update before Windows Update forces a dodgy generic driver on you. Download it from Intel's support detection page.
Use the 5GHz WiFi band instead of 2.4GHz if your router supports it. WiFi 6 works better on 5GHz anyway, and there's less interference from neighbouring networks, Bluetooth devices, and microwaves. Check your router settings (usually accessible by typing 192.168.1.1 or 192.168.0.1 into a web browser) and make sure 5GHz is enabled.
Stop Windows from auto-connecting to every network you've ever used. Go to Settings > Network & Internet > Wi-Fi > Manage known networks, and for any network you don't use regularly, click it and select "Forget". Windows trying to connect to three different networks simultaneously causes conflicts, especially if you're in range of multiple saved networks.
If you're on a laptop and you absolutely need maximum battery life, consider creating a custom power plan instead of letting Windows manage it. You can disable WiFi power management specifically whilst still allowing other components to save power. It's in Control Panel > Power Options > Change plan settings > Change advanced power settings > Wireless Adapter Settings > Power Saving Mode. Set it to "Maximum Performance" even on battery.
Check for Intel driver updates monthly. Set a calendar reminder. Intel releases updates fairly regularly, and staying current prevents compatibility problems when Windows 11 updates land. Don't wait for Windows Update to do it for you, because it won't install the right version.
Intel WiFi 6 Driver Keeps Disconnecting Summary
Your Intel WiFi 6 driver keeps disconnecting because Windows 11 is either turning it off to save power or has replaced Intel's proper driver with a generic version that doesn't handle WiFi 6 correctly. The fix is straightforward: disable power management in Device Manager (works 90% of the time), or manually install the latest Intel driver from intel.com if that doesn't solve it. In stubborn cases, a full network reset followed by proper driver installation will sort it.
The key is using Intel's official drivers, not the generic ones Windows Update pushes. And don't let Windows turn off your adapter to save power. Yes, it'll cost you a few minutes of battery life. But you'll actually have working WiFi, which seems like a reasonable trade-off.
This problem isn't going away until Microsoft sorts out their driver management and power settings in Windows 11. Until then, you know how to fix it yourself in under half an hour.
