Intel(R) Wi-Fi 6E AX211 160Mhz Netwtw14

[miksmelderis]

Hello, my Yoga Slim 9 14IAP7 laptop for the past few months has been having issues with wifi, the connection drops, unable to connect, and it is really slow. I have deleted and updated drivers several times and also changed the motherboard and things attached to it, the RAM, wifi and so on. Nothing helped.

In the event viewer every time there is an issue with a connection, multiple events are created with the source being Netwtw14.

I have also tried to change the Wireless modes in Device Manager as advised in other, similar situations. I suspect that it could be related to the 5/2.4 Ghz wifi signal because the hotspot from a mobile phone is 2.4 Ghz and it works without any issues.

Please help, I don't know what else to do!

I added a screenshot.

all of the listed things done, driver updated to the latest version available on intel website and checked the antennas, bios is the latest one even because i bought the computer one month ago and i updated considering the microcode correction on 13th and 14th processors nothing changed.

when i boot it up it works well and when i start using a little bit more the connection (video streaming, speedtest or games) connection becomes slow and intermittent

i am sending an event log attachment stating the same error Netwtw14

Uninstall the previously installed driver, then install the new driver

install this driver

Intel PROSet/Wireless WiFi Software Version 23.80.0.7 WHQL (necacom.net)

Thank you i will do it this weekend and i will let you know, by the way how is it possible that driver does not appear inside intel official download page?

[VARADHARAJAN]

23.80.0.7 was released by one of the available  O.E.M, so it's not available on the intel website, Moreover Intel releases executable file-based files,  But what I shared about that file, is an extracted file with .cat  and,.inf  so it can easily distributed.

Driver installation does not require more space using an inf file.  We can easily find extacṭ hardware device id is suitable.

I am currently using inf file, also I installed the latest driver only on my Gigabyte B760M DS3H AX motherboard

Thanking you

I want to confirm that I also have been experiencing this same issue and it's been for about a month now. On both my desktop and my NEW laptop. It's an Asus Zephyrus G16 with Intel Ultra 9 185h chip and rtx 4080 GPU with 32GB of ram. I can browse, but the wifi drops are pretty consistent and it isn't enjoyable. I've done everything that's been requested to do in this thread to no avail. NOTHING WORKS. Intel. Please. FIX YOUR DRIVERS.

Good evening

Sorry for my late reply but the affected computer is at my father's house and i don't go so often, i did the update and i tried but unfortunately performance aren't exciting 39 download 70 upload.

I casually discovered my laptop has the same WIFI component and i decided to try it as well, using the same drivers and putting at the same position of my father's desktop i registered in download a 10x improvement and in upload a 5x improvement compared to my father computer, i will do further tests. 

the distance between the computers and the router is about 6m with a wall separating them in the middle

I have exactly the same problem.
I simply can't connect to the 5GHz network anymore, and when connected to the 2.4GHz network, it's very slow and seems to disconnect and reconnect all the time, making it impossible to work.

I don't know what else to do. I've already updated to the latest driver, but it didn't help. I tried rolling back the driver version, but the system says I already have a more recent version installed.

Has anyone managed to solve this?
My computer is a Galaxy Book 4 Ultra i9.

I concluded this was a hardware fault in the end.  I've replaced my Wi-Fi card and its working normally now.

Hi,

Bought a brand new off-the-shelf ASUS STRIX G16 (G614JV-N3061W) laptop and having the same issue.

The AX211 will infrequently black out for 2 to 15 seconds before recovering. Windows 11's Signal Strength indicator remains at full.

Windows EventLog has frequent Info (ID 7003, 7018), Warning (ID 6062), and sometimes Error ("Has encountered an internal error and has failed") entries from the driver. For some reason the Event text is missing, so I have no idea what they mean.

None of the other devices i have here shown any similar issues. Updating to driver 23.90 doesn't seem to solve.

I think it's more frequent under load and it seems to happen less with ax/ac turned off, but i can't say for sure.

Does anyone have extra input on solving this, or at least a way to get the error text ?

One of the best ways to gather historical wifi information within Windows is Microsoft's tool for wireless specifically

I think I found the solution regarding these messages in the following post on MSI forums: B760 Gaming Plus Wifi - huge wifi problems with AX211 | MSI Global English Forum

So, the issue is that the Intel WiFi driver installer specifies incorrect path to the driver for logging events (for AX211, the location of the entry in the registry is: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\System\Netwtw14):

The issue is that in this string, for AX211, %13% should point to Netwtw14.sys, but it does not. I followed the advice in that post and replaced this placeholder %13% with the path to Netwtw14.sys, which is on my PC located  in C:\Windows\System32\DriverStore\FileRepository\netwtw6e.inf_amd64_<SOME_CODE>
(there were some other folders with this file, but they did not contain 6e in their name, so make sure that the folder name contains 6e, at least for AX211).

That is, the EventMessageFile registry entry should be like: %SystemRoot%\System32\netevent.dll;%SystemRoot%\System32\DriverStore\FileRepository\netwtw6e.inf_amd64_<SOME_CODE>\Netwtw14.sys

Then I restarted the PC and started getting normal, readable messages from Netwtw14 in the event viewer:

I hope that Intel will look into it and fix this issue in the next driver version.

I had many problems with the WiFi card in my ASUS board and what I discovered on another forum is that with the AX211 half the functionality has been moved from the WiFi card to the CPU and if there's any issues with the communication between the two errors like this can appear. In my case I managed to get rid of the errors by reseating the CPU.

I had the same problem for about a month, hopefully it somehow disappeared with Windows 11 minor update. AX211 wifi, Dell Latitude 5450 and 7021/netwtw14 errors in event log (sometimes different number).

I could not connect to 5Ghz/AX wifi with WPA2-PSK/WPA3-PSK authentication on Microtik Router and I assume notebook saw much less wifi networks than usual - it was possible to see SSID of 5Ghz after driver update (and maybe restart), but connection failed anyways. 2.4Ghz/G wifi worked, but slowly - there are interferences and speeds like 1-15Mbits are barely useable.

Curiously 5GHz/AX wifi worked without any problem at work with WPA2-ENTERPRISE authentication.

Have you tried taking the back off your laptop and reseating the Wi-Fi card?
