Matt16, Thank you for posting in the Intel® Communities Support.


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

Is this a new Intel® NUC?

The download speed, was it working fine before?

Did you make any recent hardware/software changes?

When did the issue start?

Which Windows* version are you using?

Does the problem happen at home or work environment?

Which is the BIOS version currently installed?

What is the Intel® Wireless driver version currently installed?


Any questions, please let me know.

Matt16, Thank you very much for providing those details.


By any chance, do you have the option to test the Intel® NUC with a different Router or AP just to verify if the behavior is the same?

You mentioned that if you connect any other device to that same Router, the download speed works with no problems, correct?

What is the specific model of the Router?

Did you check with Cisco directly to confirm if there might be a firmware update for that Router?

Matt16, I just received an update on this matter.


Based on the details showing in the SSU report we noticed that the Windows* version is not the latest one, please install all the Windows* updates all the way to the latest build.


Additionally, there is a newer driver available on our web site, please install Intel® Wireless driver version: 21.90.3 and once you get the chance please let us know the results:

@Niko87,

While they may seem similar, every user's issues are different. You have different hardware, different driver mix, different installation order, etc. In addition, Intel Customer Support wants to track each user's issue to completion. They can't do that if you are a rider on someone else's issue. Please open your own conversation for your issue (using the Post a Message button on the main (root) Intel Community page). Please include a full description of your issue, the model of your laptop, etc. in your post

If you want to save time, please download and run the Intel System Support Utility for Windows and have it save the report to a text file. Then, using the Drag and drop here or browse files to attach dialog below the edit box for the body of your post, upload and attach this file to the post. Intel Customer Support (as well as volunteers like me) use this information to help in the analysis and (where necessary) replication of your issue.

Similar issue, and fix, for me on a brand new Dell Precision laptop with AX201 card...

On first setup I was getting a high ping and barely 1-2Mbps at 5Ghz, despite ethernet connection proving the line was running at ~70Mbps as it should. 

I tried a driver update but that had no direct effect on its own - near ethernet speeds were gained only after setting a manual 5Ghz channel on the router.

(Indicating either an issue with the particular channel my router happened to be using or its "Smart Wireless" default setting in general; I believe there is a router of the same type in the neighbouring property so it is possible that could have caused a conflict.)
