How to Fix Netwtw06.sys Failed BSOD on Windows 10 and 11

The netwtw06.sys failed error throws Windows into a blue screen of death whenever the Intel Wireless LAN driver crashes. We tested every fix below on a Lenovo ThinkPad with an Intel Wi-Fi 6 AX201 card running Windows 11 23H2, and a Dell desktop with an Intel AC 9560 card on Windows 10 22H2. Driver work alone cleared most of the crashes we reproduced.

The crash points to one specific component: the Intel PROSet/Wireless driver bundle. Closely related driver-level BSODs such as the ntfs.sys failure share the same triggers and rule-out approach, but netwtw06.sys is almost always a wireless stack problem.

Work through the methods in order. Most readers stop after Method 2.

#What Triggers the Netwtw06.sys Failed Error?

Netwtw06.sys is the Intel Wireless LAN driver file that sits inside C:\Windows\System32\drivers. When the file crashes, Windows kills the kernel and shows a blue screen with one of three companion stop codes. Each code points to a different root cause, so identifying the exact stop message you’re seeing on the BSOD will help you pick the right fix faster than working through every method blindly.

The DRIVER_IRQL_NOT_LESS_OR_EQUAL message appears when the driver tries to access protected memory at the wrong interrupt level. According to Microsoft’s bug check 0xD1 documentation, this code is almost always tied to faulty drivers. See our 0x000000D1 stop code guide for the broader fix list.

PAGE_FAULT_IN_NONPAGED_AREA means the driver requested data that should have been in RAM but was missing. SYSTEM_THREAD_EXCEPTION_NOT_HANDLED means a kernel thread threw an exception the OS couldn’t recover from. Our standalone system-thread-exception-not-handled guide walks through the wider thread-level fixes.

In our testing, four conditions produced most of the netwtw06.sys crashes:

• A Windows Update that replaced the working Intel driver with a generic one
• A manual driver update that pulled an unstable beta build from Intel
• Corrupted system files after an interrupted Windows Update
• A bad RAM module flagging only when the Wi-Fi stack hit it

Disk corruption and registry damage cause the rest.

Wi-Fi adapters from Intel ship across most Dell, Lenovo, HP, and ASUS laptops, so this error is common on 2018-and-newer laptops with Intel Wireless-AC, Wi-Fi 6, or Wi-Fi 6E cards.

#Update Your Intel Wireless Network Driver

An outdated Intel Wireless driver is the most common cause of netwtw06.sys crashes. Start here.

1. Right-click the Start button and pick Device Manager.
2. Expand Network Adapters and find the entry that ends in Wi-Fi 6 AX201, Wireless-AC 9560, or similar.
3. Right-click the adapter and pick Update driver.
4. Choose Search automatically for drivers.

Windows will pull the latest signed driver from Microsoft’s catalog. When we ran this on our ThinkPad, the system installed Intel Wi-Fi driver version 23.40.1 and the BSOD stopped after the next reboot.

If Windows says you already have the newest driver but the crashes continue, grab the latest package directly from Intel. Intel’s Wi-Fi driver download page confirms that signed driver builds are released every 4 to 6 weeks and override Windows Update versions when installed manually. After installing the new package, restart the PC and watch for the same blue screen for 24 hours before moving on.

#Roll Back the Wireless Driver After a Recent Update

If the netwtw06.sys error started right after a driver update or a Patch Tuesday Windows Update, roll the driver back. Microsoft has shipped at least three Patch Tuesday rollouts since 2023 that broke Intel Wireless drivers on a subset of Wi-Fi 6 cards.

In our testing on the Dell desktop, the March 2025 cumulative update pushed an unstable Intel build that crashed repeatedly. Rolling back resolved it quickly.

1. Press Windows + X and pick Device Manager.
2. Expand Network Adapters, right-click the Intel Wi-Fi adapter, and pick Properties.
3. Click the Driver tab.
4. Click Roll Back Driver and confirm. If the button is grayed out, no previous version is stored, so skip to the next method.
5. Reboot.

The Roll Back Driver button only appears if Windows kept a copy of the previous driver, which it usually does for 10 days after an update.

After that window, you’ll need to download the older Intel package manually from Intel’s archive.

#Repair System Files With SFC and DISM

Corrupted system files can break the netwtw06.sys driver loader even when the driver itself is fine. Run System File Checker first, then DISM if SFC doesn’t clear the issue. Microsoft’s SFC and DISM repair guide recommends this two-step order because DISM repairs the underlying component store that SFC pulls clean files from.

Open Command Prompt as administrator (right-click and pick Run as administrator). Then run:

sfc /scannow

The scan takes 8 to 12 minutes on an SSD. If SFC says it found and fixed corrupted files, reboot and check whether the BSOD returns. When we tried this on a test machine with intentionally corrupted files, SFC repaired the corrupted system files.

If SFC reports it found corrupt files but couldn’t fix some of them, run DISM next:

DISM /Online /Cleanup-Image /RestoreHealth

DISM downloads clean replacement files from Windows Update, so you need an internet connection. The scan takes 5 to 20 minutes depending on connection speed. After DISM finishes, run sfc /scannow one more time. This sequence has the highest fix rate for system file damage according to Microsoft’s documentation.

Related driver-stack failures often respond to the same SFC plus DISM combo. The ndis.sys network driver BSOD and tcpip.sys network driver crash both clear after a clean component store rebuild.

#Run CHKDSK to Check for Disk Errors

CHKDSK only helps when bad sectors or file system damage are corrupting the driver file on disk. We recommend running it after SFC and DISM, not before, because CHKDSK can lock the system drive for an hour or more and rarely fixes a Wi-Fi driver crash on its own.

Open Command Prompt as administrator and run:

chkdsk C: /f /r /x

The /f flag fixes errors, /r locates bad sectors and recovers readable data, and /x forces the volume to dismount. CHKDSK can’t run on the active C: drive while Windows is loaded, so it will ask to schedule the scan for the next reboot. Type Y and press Enter, then restart.

The full /r scan takes 1 to 4 hours on a 500 GB SSD and 4 to 8 hours on a 1 TB hard drive. Don’t interrupt it. After CHKDSK finishes, Windows boots normally and writes the results to Event Viewer under Windows Logs > Application > Wininit.

If CHKDSK reports unrecoverable bad sectors, the drive is failing. Back up your data immediately and replace the drive before the next BSOD turns into permanent data loss.

The same caution applies if you’re seeing repeated IRQL_NOT_LESS_OR_EQUAL Windows 10 crashes alongside netwtw06.sys.

#Use System Restore to Roll Back Windows

System Restore reverts Windows to a checkpoint before the BSOD started. This works when a recent app install, driver update, or Windows Update kicked off the crashes and the other methods didn’t help.

1. Press Windows + R, type rstrui, and press Enter.
2. Click Next on the System Restore wizard.
3. Pick a restore point from before the BSOD started. Windows lists the date and trigger event for each one.
4. Click Next, then Finish, then Yes when Windows warns the restore can’t be interrupted.

The restore takes 15 to 30 minutes and reboots automatically when finished. System Restore doesn’t touch personal files in your user folders, but it does uninstall apps and reverse driver updates installed after the restore point.

System Restore only works if it was enabled before the crashes began. If no restore points exist, skip this step.

For a deeper rollback, our potential Windows Update database error detected guide covers how to reset the Windows Update components when a faulty update keeps reinstalling.

#How Do You Recover Lost Files After a BSOD?

A netwtw06.sys crash mid-write can corrupt files or wipe an unsaved document. Worse, an aggressive CHKDSK pass on a damaged drive sometimes deletes recoverable data along with the bad sectors. We’ve seen this on two reader machines this year.

If you noticed missing files after the BSOD, stop using the drive immediately. Every write reduces recovery odds.

We tested Tenorshare 4DDiG for Windows on an SSD where we deleted a batch of test files and ran CHKDSK on top, and the deep scan surfaced most of the deleted data. It recovered the bulk of what we lost. The free version previews recoverable files; full recovery requires a paid license, and you should boot from a USB or use a second computer rather than installing the recovery tool on the affected drive.

The basic flow:

1. Install 4DDiG on a different drive, never on the affected volume.
2. Pick the drive or partition where the files lived.
3. Run a Quick Scan first. It finishes in 5 to 10 minutes for most SSDs.
4. If the Quick Scan misses files, run a Deep Scan.
5. Preview each file and recover only what you need to a different drive.

If the data is critical and a software tool can’t see it, stop trying recovery yourself. A drive with physical damage or a complex RAID failure needs professional service, since DIY tools sometimes overwrite the only readable copy. The Tenorshare suite also has a phone data recovery tool for Android and a separate iPhone data recovery tool if your phone is affected.

#Bottom Line

Start with the driver fix, not the disk repair. Update the Intel Wireless driver from Device Manager, and if the crashes started after a recent update, roll the driver back instead. That single step clears the netwtw06.sys failed error for most people in under 5 minutes. If driver work doesn’t help, run sfc /scannow followed by DISM, and only escalate to CHKDSK or System Restore when system file repair fails.

Don’t run CHKDSK as your first move on a drive you suspect is failing. Recover your data first with a tool like Tenorshare 4DDiG, then decide whether to repair or replace the drive.
