Poor download performance with WiFi 6 AX201 160MHz - Continued

New Contributor I

I have tried to respond to my original post twice and it has not appeared in the community, despite my editing the second response twice.  As a result, I'm creating this extension post with the hope that @AndrewG_Intel will pick up the discussion from here.  I've never had these kinds of posting issued on any of the dozens of other boards I use... any guidance on maintaining a discussion thread in this community would be appreciated.


Andrew -

Thanks for the prompt reply! I responded to this two days ago and now when I returned I find that it was apparently not posted, so will attempt to do so again, but will definitely save a backup copy outside of this forum. Answers inline below.



1- We understand that the system is currently running Windows* 11 but the issue was also present on Windows* 10, is this correct? When did the behavior start to happen? Were you able to have your wireless connection in a normal/expected performance before? Please provide details.

h>> The performance has always been consistent across multiple Windows and driver versions, but became more obvious after I upgraded my Xfinity internet from 400 to 800Mb/s. The Apple devices saw a doubling of their prior download speeds while the Intel WiFi 6 only achieve 1/3 - 1/2 the speed.

2- Do you remember if this issue happened after a new Windows update or Wireless/Bluetooth driver update? Or is it happening since the first day that you have the computer?

h>> This has been consistent from the first day and across multiple WIndows and driver updates.

3- Is the Intel® Wi-Fi 6 AX201 the original wireless adapter that came pre-installed in your system or did you integrate/replace it?

h>> Original OEM adapter.

4- Have you tried a different router or Access point for testing purposes? Maybe one that is AX compatible? Have you rebooted your access point, router, modem? Please provide details.

h>> I have two router/APs to cover my house, and the difference in performance is constant across both. My router is a Linksys EA7500 AC1900 which replaced one of my two Asus RT-AC66U dual-band AC1750 Gigabit routers when it couldn't maintain a connection to my modem. The second RT-AC66U is hardwired to one of the Gb ethernet ports on the Linksys and is running in AP mode. I did a factory reset on the LInksys router after upgrading my internet service so it picked up the new provisioning information, and have done a restart of both the Linksys and Asus units several times since. Once again, both Apple devices are working fine, so my wireless infrastructure is solid.

5- Router/Access point brand and model: h>> As above.

6- To have a baseline, could you please define what would be "optimum speed"? Please provide details about your current Internet Speed/Bandwidth plan and some screenshots showing how you monitor the speed.

h>> Optimum speed would be to get the full 800-900Mb/s coming out of my modem, but that's not realistic. I think that it would certainly be reasonable for the PC and Apple devices to achieve comparable speeds. The Apple devices are typically getting 450-550Mb/s, while my PC is getting 175-350Mb/s. All systems get 23-24Mb/s upstream against Xfinity's disappointing 20MB/s spec.

7- Have you checked if this behavior happens testing only the computer and the router? (no other wireless devices connected to the wireless network during this test).

h>> Once again, all systems are operating in the same environment, sitting side by side in the same location and running the speed tests individually within minutes of each other. While I have a couple of dozen devices connected to my network, none of them are steaming during these tests.

8- Run the Intel® System Support Utility (Intel® SSU) to gather more details about the system:

h>> Attached.
