Deactivate LSO - Large Sent Offload

[Grovy]

Hello People!

I have a Intel Wifi 6E AX210 160Mhz adapter built into my Mainboard.

But recently i get alot of Event ID 7021 followed by 6062.

It always does the "Connection telemetry fields and analysis usage"

and then followed by "Lso was triggered".

Which then disconnects sensitive programs i am using.

I also have googled that the solution would be to just deactivate "Large Sent Offload".

But i cant find that option in the device manager of that adapter as you can see in those pictures.

So what is that option called now?

 

System model: Gigabyte X570S Aorus Master

Wireless adapter: Intel® Wi-Fi 6E AX210 160MHz

Driver version: 24.20.0.4

BIOS: Updated to latest version

Network: 5GHz

Protocol: Wi-Fi 6 (802.11ax)

Operating system: Windows 11

Signal strength: Excellent. Router is in the same room.

I hope ya guys can help me.

Hello Grovy,

Thank you for posting on Intel Community Forum.

Based on how you described the issue, this may be related to a driver regression or a compatibility issue with the router. To help us investigate further, please share the additional information listed below.

1. How frequently do these Event ID 7021/6062 sequences happen (every few minutes, hours, daily)?

2. Does the entire Wi-Fi connection drop, or just specific applications lose connectivity?

3. Do you remember if this issue happened after a new OS update or Wireless driver update?

4. Is this issue happening at home, office environment or both?

5. Have you checked if this issue happens on different networks?

6. Screenshot of the error messages.

I look forward to your response.

Hello Jed,

thank you for replying.

1. It sometimes doesnt happen for like 10 hours. Sometimes it does it like 3 times in like one hour.

2. Connection doesnt drop, like i said the router is in the same room. Only specific programs loose connection.

3. It mustve started since January or February.. Windows 11 is always up to date. The Wi-Fi driver too.

4. It only happens at home. Its a Desktop PC. It doesnt go anywhere.

5. I only have one router in my apartment. Therefor jsut one connection.

6. Pictures of the Event ID messages? ->

Event ID 7021 -> "Connection telemetry fields and analysis usage"

Event ID 6062 -> "Lso was triggered"

Thats all it says.

So my suggestion is to turn off LSO. But the option in device manager is just simply not there.

I dont think my router is the problem. Every other device connected to it runs just fine.

The router is a AVM FritzBox 6690 Cable.

Hi Grovy,

Thank you for sharing all this information. To further troubleshoot the issue, please try installing the latest

1. Install the latest OEM driver 22.200.0.6 and perform a clean installation. 

2. If the issue persists, try the intel generic driver 24.30.1. 

3. Perform a network reset.

Once you’ve completed the steps above, please let me know the outcome so I can continue investigating in case the issue is still observed.

Best regards

Hello Jed!

Yes i saw the new generic driver 24.30.1 released like a day or two ago.

Currently i am trying out this version.

Also i wonder why you would tell me to try out a very old OEM version of a driver?

Shouldnt the newest version always be the better choice, even after all those years?

I mean this driver is like almost 3 years old..

But yeah i am currently trying out the 24.30.1 like i said.. and it might take a few days.

Yesterday for example it didnt make my program disconnect.

But also just to get back to my very first question:

What is the LSO option in the device manager called?

I dont wanna try out drivers, i wanna turn that feature off.

Hello Sesan,

I got your files ready for you.

Hoping that these might help you guys out to understand whats happening.

And just like 20 minutes ago i got another disconnect on my program at the same time when LSO was triggered.

But the ongoing call i have on Discord wasnt interrupted in the slightest.. kinda weird.

What ended up being the resolution for this?  I am running into the exact same issue but with the Intel(R) Wi-Fi 7 BE200 320MHz chipset.  Same thing in my logs too.  The LSO was triggered and causes disconnects and I am looking to disable.  

There is no advanced option to disable the LSO like above:

However, when using the get command, it shows it as enabled for IPv4 and IPv6.

But I get this error when trying to disable using admin privileges.

This feels like an intel issue.  Using 24.30.1

Hey JB37

Theyre still investigating. Gotta wait a while.

Also if i type the command: Get-NetadapterLso

Then my Wi-Fi adapter doesnt even show up. Just my Ethernet which i dont use.

So its really weird why theres a feature on clearly seen in my Event Viewer but ya cant disable it nor find it with commands or through the device manager.

So gotta wait..

Hi Grovy,

I'm getting back in touch to confirm if you were able to perform a Network reset. If you haven't had the chance to do it yet, please see the outlined steps below.

1. Shut down your computer by clicking Start > Power > Shut Down.
2. Locate your modem and note the lights on your modem when it is normal and ready. There may be a Ready or Online light. Taking a picture with a phone is a good tactic so that you know when it’s ready to go.
3. Trace the Ethernet cord (not the screw-in coaxial cable or the power cord, but the one with a clip) to the next device to determine if you have a router.
4. Unplug the power cord (either from the back of the device or from the wall, whichever is more comfortable) from your modem, router, and any switches or hubs, between your computer and the modem, as well as any wireless boosters or access points, and leave them all unplugged for now.
5. Plug in your modem.
6. Wait until your modem’s lights show normal operation again.
7. Plug in your router, if you have one, and give it about five minutes to boot. Routers typically have no external means of telling if they are ready, but they should be ready after a five-minute wait.
8. Plug in anything else between your computer and the modem.
9. Power on your computer.
10. Once your computer is rebooted, if it is not connected to the Internet, or is still having issues, you will want to reset its network stack.

Resetting the network stack

1. In the search box on the taskbar click Start, type command prompt, right-click the command prompt result and then select Run as administrator and confirm.
2. At the command prompt (decline restarting your machine until you have entered the final command):

• Type ipconfig /release and press Enter.
• Type ipconfig /flushdns and press Enter.
• Type ipconfig /renew and press Enter. (This will stall for a moment.)
• Type netsh int ip reset and press Enter. (Don’t restart yet.)
• Type netsh winsock reset and press Enter.

3. Now restart your machine using Start > Power > Restart once more and test to see if the issue is resolved.

For more information, you can check this article: Resetting Network Devices and Network Stack

If you have any questions, please let me know.

Hi Grovy,

I'm following up to check if you were able to review my previous post with recommendations. I would also like to get the additional information below as part of our investigation.

1. Does the issue happen when connecting to a different band (2.4GHz for example)

2. What is the approximate distance of the computer from the main AP?

I look forward to your response.

Hi Grovy,

Just to provide you with additional context regarding the LSO option in Device Manager, I’d like to clarify that Large Send Offload (LSO) is not applicable to wireless connections. You can check the technical explanation below.

• LSO Purpose: Hardware offloading feature that improves performance by transferring large TCP packet segmentation to the NIC hardware
• LSO Scope: Primarily designed for wired Ethernet adapters only
• Why Not Wi-Fi: Wireless adapters use different frame structures, error correction, and retransmission mechanisms incompatible with LSO's offloading approach.

Furthermore, the 6xxx events by the Intel WiFi driver are informational (even if Windows may indicate some of these as "Warning" level) and don't need to be worried about. There should be no functional impact caused by these events.

Event 6062 LSO was triggered: LSO stands for Large Send Offload. This event means there was a large packet that we split into small packages and offload them to the firmware. When this is logged in the event viewer, it just indicates above was carried out.

If you have any questions, please let me know.

Best regards

Hi JedG,

I understand that you say that LSO is not applicable to wireless adapters.  If that is the case, the power shell commands are misleading.  What should be the interpretation of this command if LSO is not applicable to wireless devices?

Why would the power shell command Get-NetAdapterLso return that it is enabled on a wifi device when not applicable?

Also, what should be the interpretation within the system log of "event ID 6062" for wireless device that does not have LSO applicability?

I understand that you state that there should be no functional impact but I think we are stating that there is.  There is a correlation between "event ID 6062" and application disconnects with no apparent way to disable this functionality.  Something just isn't adding up.

Using an older USB netgear wifi device has resolved this problem but I would much prefer to use the Intel integrated chip.

Thanks,

Hello Jed and JB37,

so as asked i didnt do a reset of my network stack but i reformated the whole system.

using the 24.30.1 version obviously for now with a fresh updated windows 11.

my router doesnt need to be rebooted, it does it on its own.

for the question if the AX210 uses 2.4ghz or 5ghz, that depends on what the AX210 wants.

since i already said that the router is in the same room i dont see the need for 2.4ghz.

the router is maybe 5m (16ft) away from the computer, just to answer that question.

so 5ghz shouldnt be the problem.

and JB37 is right.

if LSO is not applicable to wireless connections then why the heck is it still doin these things?

for his BE200 device it is even showing in powershell which i cant see for my AX210.

but yet it still does the trigger. like i already said in an earlier post:

its really weird why theres a feature on clearly seen in the Event Viewer but ya cant disable it nor find it with commands or through the device manager.

resetting my stuff is just nonsense so far.
