7.18 Encountered the same problem

[tsreal]

I have the same problem.
OS: Windows 11 23H2 22631.3880
BSOD error info: driver_irql_not_less_or_equal netio.sys
When I turn on the game accelerator and open a few web pages with adguard on, the computer will immediately turn into a blue screen state.

[iTravelcard]

I'm experiencing the same issue. I've had two crashes so far, both with the DRIVER_IRQL_NOT_LESS_OR_EQUAL error. In my latest crash dump, I noticed the driver adgnetworkwfpdrv and found this GitHub page.
I’m running the stable version 7.18.1 on Win 11 23H2 22631.3880.

[xywcloud]

I'm experiencing the same issue
I've had five crashes so far(same err code and driver name)
Plz fix it ASAP

2024.07.25 Update: now I have 7 crashes so far, one happened just now

[MikeWuang]

I'm having same issue

I also got netio.sys bsod after installed the AdGuard , although my minidump says it's NLSvc.exe ( NetLimiter ) and another one is AVGSvc.exe ( I have AVG installed ) but my pc is completely stable before installed adguard .

I experienced this netio.sys BSOD once about a week ago (which is the first BSOD I've had in literally years) while watching a YouTube livestream in Chrome. I didn't see this topic until now, so me too. It only happened once though and haven't been able to cause it again. Using Windows 11 24H2 and Windows Defender.

[AngryBoT1229]

I have expericenced similar problems, netio.sys BSOD about two times and adgnetworkwfpdrv.sys BSOD one time so far.

AdGuard Version : 7.18.1
OS: Win11 23H2 22631.3880

I decided to uninstall the Adguard now to see if the BSOD occur again or not.

[tsreal]

I have the same problem. OS: Windows 11 23H2 22631.3880 BSOD error info: driver_irql_not_less_or_equal netio.sys When I turn on the game accelerator and open a few web pages with adguard on, the computer will immediately turn into a blue screen state.

After I disabled the WFA driver, everything returned to normal and there was no BSOD.

[AyratSaubanov]

Dear Sirs,
could you please provide us any estimated time for this issue? It makes absolutely impossible to use Adguard as it leads to crash every time i use it.

[adbuker]

@AyratSaubanov , as a temporarily solution you can enable TDI driver. As for solution time's estimate - we'll try to do our best and fix it asap, I guess with a couple of weeks

[shinji257]

Just wanted to hop in and say that this issue is present for me as well on 7.18.1 I've only started hitting this over the last week or so but I might have been lucky prior.

Here are some minidumps for reference.

[BooBerry]

Starting to see it happen a little more too now (twice within a few days), also on 7.18.1. When a fix lands in nightly, hopefully it also quickly lands in beta too, but it really needs it.

[shulymn]

Can confirm it is an issue caused by the WFP driver.
A while ago i switched from 1gbps internet to 2.5gbps internet and I discovered that adguard was limiting my browser speed to ~1.2gbps. I contacted adguard's team and they told me to activate the WFP driver.
It fixed the speed problem but caused BSODs, so i reverted back.
Now the WFP driver is activated by default when you install Adguard.

[Aydinv13]

We've published a new Nightly, so could you check it please.

[AyratSaubanov]

We've published a new Nightly, so could you check it please.

It looks fine now on a new nightly version - Adguard was used for a whole day without any crash.

[Aydinv13]

Here's another improvement, could you install this version please or just update through the app.

[AyratSaubanov]

Here's another improvement, could you install this version please or just update through the app.

Version "7.19.0 nightly 4" is working fine for a couple days now. No crash occured.

[ScarletKuro]

I am experiencing the same BSOD problem(version 7.18.1). I first noticed it on my stationary PC and thought it was an issue with the PC itself. However, when I started working on my laptop, I observed the same crashes occurring while browsing the internet using Firefox. The only thing in common they have is the AdGuard. Pretty sure 7.17.* had no issue as I started to get the BSODs recently.

[adbuker]

@ScarletKuro , please update to the latest nightly or the beta version

[trparky]

Nope, I just got a BSOD with references to netio.sys.

[zengshengliu]

I am on 7.19.0 nightly 5 and still getting BSOD with NETIO.sys.

[adbuker]

@trparky, @zengshengliu, please grab and send the logs (instruction here) to the devteam@adguard.com with the issue number in the letter's label

[KolbasovAnton]

Hello, check our new nightly version, it has some BSOD-fixes.

[BooBerry]

Hopefully the new fixes land in the beta channel sooner than later.

[zengshengliu]

Just got a BSOD for nightly 6 build. I will enable debug log and submit them when I get another BSOD.

[adbuker]

@zengshengliu , be a pity. Could you please send the minidump to the devteam@adguard.com with the reference to this issue

[zengshengliu]

Hi @adbuker
I submitted the debug log along with minidump of the latest crash (about an hour ago) on the latest nightly 7 version via the email provided.

[iTravelcard]

After a couple of days without a BSOD, I had one today related to netio.sys. I am using the nightly 7 build.

[adbuker]

@zengshengliu , @iTravelcard , please udpate to the latest nightly, a new bunch of fixes are bundled here

[zengshengliu]

Just updated to nightly 11, will report back if I see more crashes (or the lack of)

[adbuker]

@zengshengliu ,I hope the second one option :)

[iTravelcard]

@zengshengliu , @iTravelcard , please udpate to the latest nightly, a new bunch of fixes are bundled here

It seems that this problem is not fixed yet, Windows still crashes on nightly 11.

[adbuker]

@iTravelcard , have you tested with the latest nightly?

[iTravelcard]

@iTravelcard , have you tested with the latest nightly?

Just installed 7.19 Nightly 12, but need to test more because the BSODs occur completely randomly.

[Minpatsu]

Just got BSOD with 7.19 nightly 13. happen when i open 3 tab of twitch stream.

[trparky]

I have to wonder what other security software people are using. Maybe there's a conflict.

In my case, it seems that my system crash issues with AdGuard went away when I stopped using Avast. Don't laugh, I was stupid. I've since switched to using nothing but Windows Defender.

[BooBerry]

It happened to me using only Windows Defender. It hasn't happened with the last few nightlies yet but I'm watching for it.

[trparky]

OK, I contributed my issues to using Avast. I was just going out on a limb with this.

[shulymn]

It's not related to AV, I don't use one and Windows Defender is disabled.

AdGuard Version : 7.19 beta 2
OS: Win11 Pro 24H2 (Build 26100.2033)

No problems with Windows 11 Pro, 23H2 (Build 22631.4249).
BSOD started 3 days ago, after the upgrade to Windows 11 Pro, 24H2, (Build 26100.1882).

I didn't see this topic until now, and as temporary workarouund I followed the adbuker advice ( commented on Aug 6):
"as a temporarily solution you can enable TDI driver".

[Jermelescu]

I get BSODs on my two laptops, but my PC works just fine.
Most of the errors are related to the power management somehow when the laptop tries to shut off the display or occasionally when I open new tabs in the browser.
Removing Adguard gets rid of the BSODs, so there's that.

This has been going on for a few years, more often on W11 than on W10.
Edit: reading above that someone has had issues when opening twitch tabs, I can confirm that it happened to me too on twitch most of the time if not all the time. Last BSOD related to the tabs (Edge and Chrome) was a couple months back.

Confirm, with TDI driver no more BSOD.

What's a TDI driver?
