AX211 Wifi Throttling

shadowoflight — Sat, 09 Dec 2023 07:48:20 GMT

Just got assigned an Lenovo x13 gen 4.

Everything’s great, except for some reason, the wifi's getting throttled to ard 40mbps.

I can go beyond that using speedtest, but when synology, Google drive, office installer, adobe etc, are running, you can see spikes when a new software starts downloading, then it drops to 30mbps max alone (i.e. just google drive syncing) or combined (g drive and synology syncing, adobe downloading installs).

Haven’t tried ethernet because there’s no need for it so far in this job. All on Wi-Fi. Same on different networks, office, home and public. Speed is definitely not an issue because I've gone much faster on the same networks on both my personal and work laptops.

I've tried :

(from here
Press Windows Key + X.
Click on Command prompt (Admin).
Type the following commands, and hit Enter after each command:
netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set global rss=enabled
netsh winsock reset and press Enter
netsh int ip reset and press Enter
ipconfig /release and press Enter
ipconfig /renew and press Enter
ipconfig /flushdns and press Enter

after that didn't work, I tried (from here
setting: netsh int tcp set global autotuninglevel=normal

Specs:
Thinkpad X13 Gen4
i7-1355U
32GB Ram
1TB SSD
Wifi 6E AX211 (Driver 22.240.0.6 18/6/2023)

I tried downloading the latest driver (Nov'23) from lenovo and intel's site, but after I run the executable, it says the best driver is already installed.

Any ideas?

shadowoflight, Thank you for posting in the Intel® Communities Support.

We are sorry to hear about this issue and we will be more than glad to assist you with this matter.

In order for us to provide the most accurate assistance on this scenario, we just wanted to confirm a few details about your system:

Is this a new computer?

Was it working fine before without the Wi-Fi throttling issue you are describing?

If yes, when did the issue start?

Did you make any recent hardware/software changes that might cause this issue?

The wireless card, did you purchase it separately or did it come installed on the computer?

Does the problem happen at home or in the work environment?

Please attach the SSU report so we can verify further details about the components in your platform, check all the options in the report including the one that says "3rd party software logs":

Is this a new computer? Yes

Was it working fine before without the Wi-Fi throttling issue you are describing? No, this was a day 1 problem

If yes, when did the issue start? Day 1

Did you make any recent hardware/software changes that might cause this issue? No, it was like this out of the box. Lenovo event changed the wireless card and the problem persists.

The wireless card, did you purchase it separately or did it come installed on the computer? With the laptop.

Does the problem happen at home or in the work environment? On all wifi networks (2 at home from different ISPs, 2 in office), no such issue with other laptops on those networks

Please attach the SSU report so we can verify further details about the components in your platform, check all the options in the report including the one that says "3rd party software logs": Attached

shadowoflight, Thank you very much for providing that information and the SSU report.

Based on the information shown in the SSU document, we can confirm, as you mentioned, that the wireless driver version currently installed on your computer is 22.240.0.6.

For this scenario, it is important to mention that we always recommend to install the wireless driver provided by the manufacturer of the computer, since that driver was heavily customized by them to work with your specific platform.

I looked on Lenovo's website and the latest graphics driver version they have available is 22.250.1.2. Please try a clean installation of that driver following the instructions in the links below:

https://www.intel.com/content/www/us/en/support/articles/000022173/wireless.html

Driver:

https://pcsupport.lenovo.com/ag/en/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-x13-gen-4-type-21ex-21ey/downloads/ds566258-intel-wireless-lan-driver-for-windows-11-version-21h2-or-later-10-64-bit-version-1809-or-later-thinkpad?category=Networking%3A%20Wireless%20LAN

If the issue persists after that, then try a clean installation this time of Intel® wireless driver version 23.10.0.8:

https://www.intel.com/content/www/us/en/download/19351/windows-10-and-windows-11-wi-fi-drivers-for-intel-wireless-adapters.html?wapkw=ax211

We also suggest to get in contact directly with Lenovo Support to make sure the latest BIOS version is currently installed in your machine or, if necessary, to gather the instructions on how to update it:

Once you get the chance, please let us know the results.

Hello shadowoflight, I just received an update on this matter.

After reviewing the case, we would like to inform you, that we can confirm this is not an Intel® driver issue. Based on that, we recommend to get in contact directly with Lenovo Support so they can perform a physical inspection of the device for antenna or other component issues:
