Intel WiFi 6e AX211 low download speed

[lcq]

Hello,

I have a ThinkPad X1 Carbon 11th Gen (Type 21HM) Laptop with a Intel WiFi 6e AX211 adapter in a Windows 11. Recently I got fiber internet and got a new router - a TP-Link AX1800 WiFi 6 Router V4 (Archer AX21). The issue is the download speed I get in the laptop are way too low, around 0.04Mbps (the upload speed is normal for my contracted internet). Other devices - phones, iPads, PS5 - get regular speeds. The laptop has no issues when I connect it to my work wireless network. I updated the drivers, updated Windows, disabled and enabled the adaptor, reset the router, tried a bunch of different random troubleshooting stuff I found online, but nothing helped. 

I'm guessing it's an issue between the router and the adapter - my spouse has a Dell laptop running Windows 10 with the same Intel WiFi 6e AX211 adapter and has the exact same issue as me in our home network. Does anyone have any idea how to fix it?

Hi Lcq,

Thank you for posting in Intel Communities.

I know that you have tried a lot of things and I think our goal is to provide you recommendations that you have not yet tried. For that, kindly provide the following information:

1. It would really help us if we can get more information about your system. Please download and run our Intel® System Support Utility from this page. To run it, please press "Scan". After the scan is finished, click next and there will be a save button, giving you an option to save the logs to a text file, please do so and attach the file on your reply. You can refer to How to get the Intel® System Support Utility Logs on Windows* for instructions.

2. Did you already try the drivers that are available on your laptop’s support site?

3. Do you know how to access the router’s GUI Set up particularly the Wireless Settings of your router? If yes, is Smart Connect enabled?

4. In connection to item number 3, if Smart Connect is not enabled, what is your Channel Width, Channel and Mode settings?

5. How strong of a signal are you getting from the wireless router in signal bars?
